Friends! We need your help with sharing (retweeting, posting the link to) this video, so other open-source photoscanning folks can find it! Can you do it for us plz? :)
sure
Certainly
Post it on reddit
@@Deezsirrer in /r/blender?
@@GlebAlexandrov yessss
Dude! I can't believe you gave away a one-hour video tutorial for free. This is incredible!
Thank you Gleb!!!🙏
We will upload this updated version (that you see here) for the course owners as well. An interesting side effect of adapting the course videos to TH-cam is that the videos get back, updated, reworked and extended, like this one. And hell, anyway Meshroom open-source workflow *MUST* be a freely available video :)
Welcome to the internet.
Brilliant!! ..very easy to follow and delivered with great finesse and articulation .. great tutorial.. many thanks from down here in Australia!!
I just started my photogrammetry journey, got a nice drone and all that's left is to learn! Keep up the good work! You explain things very well!
This was really helpful! I was trying to figure out meshroom for a school project and this made it *so* much easier to understand :)
Great tutorial. I didn't plan to watch the whole thing now but was dragged into it, it's like telling a story. Really great information in there too!
Really? That is so pleasant to hear, I've always wanted to do something that involves narratives and storytelling, so it's so kind of you to mention that aspect!
Thank you Gleb .. wonderfully produced. I learnt tons.
Hi Gleb, awesome video, again. A pleasure to learn with the free software community. Many thanks for your teachings. Very well explained! Eskerrikasko!
Thank you for taking your time out to make this very comprehensive crash-course on Meshroom/Blender. You have my eternal thanks, brother.
no problem! :)
Bro TH-cam way to comfy with these double 15 second adds
Thank you for this video. I've watched a few and it's very clean that you understand why you are doing every step and you communicate that rather than just presenting a half understood flow like so many others. I'm looking forward to reprocessing my last scan using what I've just learnt.
We try to approach it methodically, and I'm so glad to hear that it shows. Thank you!
thank you very much Alex for the great tools and great effort you put in...good luck for future tutorial :)
Holy wow man. Recently picked up a nicer camera as my phone was causing a lot of frustration. There's a lot I didn't realize I could/should be doing to improve my workflow. I really appreciate it! Subbed
This deserves more exposure. Thanks!
best tutorial I could ask for! Thanks for sharing!
I love your channel so much man, keep it up!
You're too kind!)
Thanks in advance buddy! 8 minutes in and already learned a ton!
Stunning ! Thank you so much !!!
Wonderful! Exactly what I need right now! Thx Gleb!
Don't pretend you weren't making this course too, lol ))) STOP this, Nik)
perfect. thanks! Ill give a try!
Awesome! Thank you so much for sharing it for free! ))
Andrey, no worries! this workflow deserves to be popularized as widely as we can of course.
Hey Gleb .....this is awesome, i am into photogrametry for some time now. I am very much inspired by your workflow and results. When trying to learn about photogrammetry there is almost no tutorials out there for taking proper pictures. So man, it would be so useful if you make a quick tutorial or tips on taking photos for photogrammetry.!
Vijay, we have covered it extensively in the course, but to start with, watch this tutorial: th-cam.com/video/JLdxBtECGuc/w-d-xo.html

Gleb, great job! This video inspired me to use Meshroom over NVIDIAs native alternative.
Thanks a lot Gleb, this is super interesting! Keep being awesome!
Glad you find it interesting! Is it hard to follow along btw?
@@GlebAlexandrov I didn’t think so! You’re very good at keeping a good pace without going too fast, I’ve always appreciated that about your videos.
thanks gleb for all of this information! love you man
We thought we must make this alternative workflow available for everyone, even though we pursue a different one (involving Reality Capture and some other software) ourselves. Meshroom and open-source cross-platform apps in general are the future.
Thanks this is gold :D. The Tiffs I exported didn't have Metadata at first BUT if you go to export tab and hit ≡ preset button > preferences.. > you can checkbox exif data and any other metadata as well! Just posting in case someone is having trouble with camera data not exporting with tiffs
I had that problem and I was using exiftools to copy the exif data from the original images. Lol. I thought it was a bit stupid to do it that way. Thank you.
Did i just watch a whole hour of this 😮 Its cool!!
Thank you for this!
Hi Gleb, many thx for that outstanding video. Greetings from Germany
Excellent video. Thanks
16:45 you can totally select multiple nodes just like in Blender. Awesome video btw, now I can give photogrammetry a shot. Thanks.
Thank you so much for this video! I've finished to do my first photogrammetry of my sculpture. Well, the sculpture need more sculpting process in Zbrush, but the main forms are very well. Probably I'll bay your course later.
Timofey, I'm glad to hear your first attempt ended up successful! Photoscanning sculptures is so much fun, when I told my son he could get his clay sculptures into computer, he's now asking me to digitize it :)
Great work dude 👍
Thanks! Feel free to share on socials!
Thanks for this. I've just finished a lighting rig and turntable system to scan objects. I slowdown was going to be Meshroom nodes, but this will help with understanding expectations.
Hi John, glad to hear that! If Meshroom proves to be TOO complicated, I recommend trying Metashape or RC to see how it works for you, just for the sake of comparison/research.
@@GlebAlexandrov thanks for that! I'm interested to see how the mesh noise looks. I'll share my experience feedback shortly. I'm using a similar workflow as you except with Lightroom. As as you've so rightly pointed out, a project's top challenge is often workflow! Take care and thanks again.
Awesome! thanks Gleb
amazing work!
Wow such a great tutorial
Man this tutorial is brilliant, I finally don't feel like a moron and it works!
Bless you man for your generosity, really appreciate it
No worries! :)
Great video!
Now I understand how to use Meshroom better.
Awesome! Are the other parts of the workflow clear enough? e.g. processing raws in Darktable.
@@GlebAlexandrov Your explanation is fine. I got a bit stuck on the new commands that I don't know because I'm not familiar with Darktable and Meshroom. I can re-watch the video, so it's not a problem.
Man...u are the God of blender world! Another mind-blowing tutorial!
We thought it's about time to release a sequel (or is it remake?) of our 'free photoscanning' tutorials. 100% free pipelines are tricky to setup, so the usefulness potential is high.
@@GlebAlexandrov indeed.....great precision cut stuffs like these are going to create effortless workflows in general.
Excellent, thank you
Thank you so much, Gleb!
We're trying to be helpful to our open-source community too :)
Thanks for this!
... sehr sehr gut! 👏 Thanks!
☕
thanks for the video :)
thanks a lot explaining what and how, but the most important why.
Thanx for this video bro
Whats an absolute legend. Thanks for the tutorial
You're too kind Nkanyiso!
Thank you for including the subtitles in the video - very much appreciated it!
The understanding that someone might need it keeps us doing it, otherwise proof-reading and manually fixing subtitles is so tedious, honestly! :) Hours and hours of work and it's hard to tell if it's really useful.
Very interesting !
very informative and covers some advanced workflows. I also use a two-image set approach to creating models, although have avoided sharpening as was concerned it might create false data points, have you compared the results of both sharpened and unsharpened?
So you're going to update this section within the Photogrammetry course as well!? I've just started and I'm already getting updated content...woohoo! You're doing the lord's work, mate! 😍
John, of course! It's uploading now. The project files in Drive will also be updated shortly :)
p.s. aaaand more bonuses is in works!
@@GlebAlexandrov You're the hero gotham deserves! 🤣
Gleb Congratulations. This video is a monument! Thanks a lot for your tips....I make photogrammetry with 3DF Zephyr but I think to Meshroom now because you! At soon....
Thanks!
No dude Zephyr, reality capture and agisoft all of them are better than meshroom.
What takes 2 hrs in this software would take like 6-8 hrs in meshroom and the resulting final mesh would have more problems and holes in them
Great!!! 👌
great video thank you
you are a blessing
I'm stuck at the Texturing2 node because LSCM doesn't seem to work. I even played with the decimate settings to bring the model down to around 300k faces but LSCM still fails. Basic works no problem but then I'm stuck with 3 EXR texture files instead of one. I've seen posts from others who are having trouble with LSCM and also with 2021.1.0. Any ideas? (Great video btw, really clear and easy to follow)
Hi! could you solve the issue? Same situation here
@@arturmarti9640 Sorry no luck here. :( Good luck!
Hi Gleb, thank you so much for this in-depth tutorial. I was wondering if you still have the project files somewhere? The Google Drive link in the description looks broken. Thanks!
finally some new video :D
haha) indeed!
Helo Gleb, it is very nice from you to share your knowledge this way, it was a very didactic and complete explanation about how to work with these tools. Thank you very much for your kindness. I have a technical question: there exist, under this meshroom program, the posibility to take pics in diferent positions (X,Y,Z) i mean to turn upsidedown an object to get the belly and all the details, or it is just one position to get all the pics? And in the case that you can get all the positions (X,Y,Z) how you can work with them to get the final 3D model? Thank you very much, Best regards Rodrigo.
Спасибо! Прекрасный материал.
Стараемся! :) Есть что докручивать, но в целом рабочий пайплайн.
Hey Gleb thank's a lot for this video now i use meshroom all the time !
I was wondering if there was a way to save the nodes settings on meshroom, to not redo all the changes?
Thank's again have a great day
Thank you!
You too, James)
LSCM texturing fails in latest versions of Meshroom. Do you know of any fixes for this? Is there a way to combine the textures from the BASIC unwrap method?
woah it took me years to develop this kind of workflow using only free softwares! i should just have waited for this video to release...
haha, no need to wait, Rémi! It's great that you did it on your own :) Like Ozzy singed, Life Won't Wait for You, My Friend :)
Thank you
GREAT!!!!!
First of all, thank you so much for making this amazing tutorial just a note for anyone having a problem using LSCM unwrap, just change it to basic and it will work fine, I don't know why is this happening think its just a bug
thanks for the tip.
Hi Greb. Great tutorial (I watched at it only now), as usual.
A question: I have takena video around a statue, turned that into images and used the frames in Meshroom. The point cloud looks OK, but the mesh only reconstructs the environment around and not the statue. If I constraint the meshing with a box I basically get a box as a mesh. Any suggestions?
thank you so much for this video! I wanted to buy your course but I have no money, so this video is a life saver!
Glad it works this way for you! creating 3d from photos is a vast industry, there's a place for both open-source and proprietary software/workflows.
Thanks for the video.
The Project files aren't available in that link any more.
It'd be great if you could share it for us to follow along with the video.
😮😨😱 that was amazing.. thank you so man!
thank YOU!
Thank you so much for your tutorial, Gleb! it is very helpful! By the way, I tried to calibrate the color in Texturing image, which is explained at around after 36 minutes of your video, but it doesn't work as you did. I put the path of the 'meshroom_texture' folder in the duplicated 'PrepareDenseScene' node, but I couldn't compute it. Is there something to be considered for my problem?
I am using 'Meshroom 2023.1.0'. Thank you again for your tutorial!

Hola Gleb, greetings from México! I purchased this course as an early bird and I'm still looking at it, it is so dense and basic at the same time, as photogrammetry is. I'm an archaeologist and I use photogrammetry for my surveys and research. So, I constantly work with very complex meshes and non-symetrical shapes. Usually, the optimization of the HP is very very hard to do. I've tried Zbrush (z-remesher and dynamesh); I've tried Instant Meshes and now I see your workflow in Blender with Decimate Mod.
The question is, what about the diferrence between quads and tris? Because sometimes I found myself in the need to retopologize de mesh to cover holes or segments of the mesh that need a hand, and working with quads is a bit more easy.
The second question is a bit obvious, but I think that this workflow (in Blender) is more extreme to for the PC with very dense meshes, from 20-50M polygons, because you decimate and then you subdivide and so on. This processes are very harsh for the GPU and CPU and eventually causes crashes with no further road. Obviously you need a very strong computer to do so.
Did you ever try the voxel remesher?
"so dense and basic at the same time" - perfectly describes photogrammetry indeed, easy to learn, hard to master :)) "what about the difference between quads and tris?" - each quad is composed of 2 tris, so that's an abstraction meant to ease modeling a bit, just like you've mentioned.
What was the second question, what's the better workflow for working with multi-million polygon meshes, right?
@@GlebAlexandrov yes, Gleb. That's the question. As a person that works with cultural heritage I need to keep the original mesh intact, so with some decimation tools I see a bit of 'smoothness' or changes in topology, that happens when you exaggerate the decimation.
Thank you☺️☺️😉
And you too :)
Привет!
Как поступить, если в файлах кадров нет данных EXIF? Например, если кадры получены не с камеры, а путем раскадровки видео. Столкнулся с тем, что без EXIF Meshroom не может сообразить, как реконструировать положение камеры, и вместо ожидаемой модельки получается сборище сфер.
Very cool, Alexander. Any recommendations for Lightroom settings? Thanks
imgur.com/a/8aTESML - here I made a graphic illustrating the Lightroom settings that give the result similar to Darktable (with the settings we use from this tutorial). Basically, the color profile is set to Neutral, the highlights to +70 or something, the shadows pulled up, and the Tone Curve adjusted in this kind of way.
@@GlebAlexandrov Amazing
Глеб, гуд ворк! 👍
сенкс!
Hi, is that possible to mix photos with different exposures settings? I've got a window in the middle of the room that I can't cover up, so I need to find a solution.
Thanks a lot for this great tutorial, I have a question, how do you make that rotating endresult in Photoscanning tutorial result videoclip?
Thank you! I made it in Blender, the orbiting animation and so on.
It blows my mind that this tutorial is available completely for free
Just like Meshroom itself :)
THX!! 🤍
Pers9nally...this process made my models look like they had Desease boils on them so I found it all to be pretty usledd personally
Sorry to hear it, James! Have you tried other photoscanning software to compare the results? Say, Reality Capture or Metashape for example?
stay on tune with what you want to learn, just because it's hard now, doesn't an it's impossible. It's all about ntal mindset and
Do you know if it is possible to use Mushroom on a bunch of digital pictures... pictures without shadows or backgrounds? I have 60 images of a 3d rendering from every angle and I would like to convert it back into a 3d rendering. Thanks
thank you gleb, that helps a lot
❤️
I know this is a dumb question, but, how are you moving the node window left and right like that? Nothing seems to make that happen for me.
Great tutorial! Just downloaded meshroom last night and trying to do my 1st project. I hung the part from stings in my garage and then took all the pictures. After following this tutorial I got a model of the inside of my garage but not the part! Any ideas what happened?
Pictures were taken inches away from part to acquire detail but now it's not even in the model.... like the program just ignored it and focused on all the back ground objects
It's part of Meshroom's small feature removal. It expects the background to vary quite a lot, and assumes the subject to vary little from pose to pose. So try putting your object on the floor of your garage or on your driveway, and take pictures from a further distance.
I hope you don't mind all the questions but I now have two mesh files (original and augmented) and want a final combined one to proceed with Printing. Can You direct me to a tutorial on how to get the two combined into one? Thanks
Sir, how do I display a 3D grid in Meshroom? I've enabled it, but it's not showing up. So I'm confused about the geometry.
Hi Kevin, try clicking this icon: imgur.com/a/ITQo3xq
здравствуйте прошу помочь с выбором обучения по профессиям так как я новичек:Профессия 3D-художник окружения с нуля до PRO,но по деньгам там уж затратно и по времени,но охват материала там больше или выбрать 3D-художник а потом поступить еще на какие нибудь курсы?,плюс я еще буду учиться и проходить практику по другой спецальности у меня времени физически на все не хватит.
Your color correction card Where did you get it and the case? I see a bunch of color correction cards on amazon offering 18%grey,white and black but nothing offering 50% grey. Can you link where you purchased its?
The 18% grey cards are what you want and the one Gleb's using is an 18% grey - which corresponds to a 50% luminance value - we perceive light non-linearly, so a half-grey tone is at 18%. I'm no doubt over-simplifying (due to not knowing the deeper stuff) but that's enough to know which gray card to buy 🙂
For me the MeshDecimate node is not necessary anymore, I can import the mesh direct in MashFiltering node. Maybe a meshroom version problem.
Thank you for sharing this. I am archaeologist. I want to add measurements and georeferenced 3D object to add the data into QGIS. How can I do that process ?
Hi Allianoi, not sure if that can be done in Meshroom to be honest. I found this thread, I'll google it some more though but feel free to do your own research too: github.com/alicevision/meshroom/issues/1133
Also, maybe worth demoing the Reality Capture with the PPI license and see if it can do it.
Hi, I am stuck at the Texturing. Unwrap Method LSCM doesn't work. Any idea please? Thanks!
does it have a workflow of reducing points into normals baking like RealityCapture
Iam working through this but one thing isn't totally clear...after doing the first batch of changes for texture... do you switch back to the original set of pics to do the geometry set or do you keep using the texture set and apply the geometry changes to that?
We keep using the texture set and apply the geometry-related changes to it (and export into its own folder).
@@GlebAlexandrov ok excellent! that's what I ended up doing before reading this reply. :) thanks for confirming!
Isnt ther a selected to active backing option? Or does that not work for height maps and only on normaland albedo
Yea what a bummer selected to active does not work for hieght
