Blender Secrets - Reconstruct a Face / Head from just a few photos with Keen Tools Face Builder
ฝัง
- เผยแพร่เมื่อ 14 มิ.ย. 2024
- If you want to reconstruct a face, but you don’t have enough photos for photogrammetry, you can use this tool. It only needs 2 or 3 photos and does most of the work automatically, with only a little bit of manual finetuning needed. It’s a paid addon but the demo version works for 15 days so you can get quite a bit of work done for free. Get it here: keentools.io/download/facebui...

aight, time to create models of my friends and make a mutated thingy out of it
oh god have fun lol
I'm here for this purpose, it's so fun omg
Cant believe he did that in less than a minute. Others wouldve taken like 40 minutes with like 39 minutes of blah blah blah. Then the last minute wont even tell us how to do it.
Now imagine how good his written manual is... yup, it really is that good.
Man I LOOOOOVEEE the way you make your videos... coming from 3dsmax and really just want 1minute videos to explain blender.. and yours are INVALUABLE!!!
Thank you!!
I was always thinking there should be something like this and then you just made it happen. Man i can't thank you enough
I agree you make really watchable and learnable videos, my favorite
Simple and great working tool, thank you for that!
Now that you have told it, it is no longer a secret.
Wow that is a really nice addon
Great! Thankyou so much:)
Thank you 🙏 and I’m also super happy with your book 🤙 thanks, absolutely best money I have spend last year
Nice, thanks!!
Say I made my own head mesh already. It has shape keys and rigs. I don't want to use the one that comes with FaceBuilder addon. Is there a way around where I swap my model head for there's and just tweak my own head mesh and use Facebuilder as normal? If possible that be amazing bc my own head mesh and body topology would already be the same.
Awesome tutorial ! Plz make a video on how to do lip sync in blender in an easiest way😊
Nice. Notification works again! Thx you.
Yes! It's because TH-cam was listing them as "shorts" and you don't get notified of those. I solved it by making it longer than a minute.
Thanks a lot Jan
Only a few clicks needed to create high quality nightmare :)
Wow thanks
That is cool
The 1st time i got notification.i hope will get notification for future videos also
Yes, it's solved! Apparently TH-cam was listing my videos as "shorts" (their Tik Tok format) and you don't get notified of those. It's really aggravating, and I only found out because some other people told me about it (I can't see on my end if something is a "short" or a normal video). Thanks, TH-cam! But anyway, I make them all a bit longer than a minute now and they'll be considered "normal" videos so everybody should get a notification.
do you need to have images for all angles before you get a model mesh? can't you just use one, like the front, would that be ok?
Worth
hi, i know im a bit late but how did you flip the pin mode around to do the back of the head?
so it's a generic head model you can use soft selection to tweak..?
Will it come out hollow if you 3d print the head?
It was free last year, the day I found this addon was the day it became a paid addon 😑
Also $149 per year for a Personal License = It's a big no from me. :/
Its free now, isn't it?
@@froztbytesyoutubealt3201 it's not, you only get a demo with no licenses
Yo ho ho
Sr. Good day I've already downloaded the tools but after i opened the folder there is no keentool io so how could i install it in the blender
wow
Whoa
How do you turn one of these faces into a jpeg image?
So this is how Valve made the Human faces in their games xD.
Request Add ons Extreme Pbr pls
Has anyone ever tried to retopo a head made with FaceBuilder?
Has anyone ever tried to 3d print that?
I'd really like to see the results.
I think the topology is pretty good and clean, not sure why you’d retopo it? If you want to 3D print it, you’ll need to close the hole at the bottom, or give it thickness.
@@BlenderSecrets Oh, thanks!
Can you make a face with facebuilder keentools from blender and attach it to a gta v ped?
I always love your videos but this one is kinda off for me. It would've been a nice addon but the pricing is really weird for a free software. For that price you can get Reallusion's CC3.
To be honest I just used it because I needed to have a digital double for a short film, so a couple of hours of use was more than enough. I like that it was so easy to learn to use and that it helped me finish the task. The price for the continued use didn’t really seem that important to me, as I suspect most people will just use it when they need to create one head, and the trial is more than enough. But, if you’re doing this kind of work on a regular basis I think it will pay for itself. I don’t know Reallusion though.
Click ok to create a thing of nightmares, jk awesome stuff! Is there an addon for full body models?
Sure, there are several solutions. A free one is MB Lab. I'll publish a video about that next week.
@@BlenderSecrets Free addons are more likely to find a following among your audience. You're right, this Face Builder thing can be used extensively within a month's time, but at $149/year for a personal license, I don't see many Blenderheads give this thing a permanent place in their toolkit.
@@BlenderSecrets cool thanks! I know of MB Lab but the licensing is a bit of an issue.
@@silchasruin4487 There’s also Unreal’s (or Epics, whatever) Metahuman, which is pretty nice. Actually I’m not sure if that’s just heads or entire bodies, but it works pretty well.
@@BlenderSecrets yeah I heard about that thanks! Only downside is that you can only use it with Unreal and I don't think they've added body manipulation yet.
Can the older free versions still be used on Blender?
No. I tried a few times.
@@pakilla4578 Really? So sad. I still believe that Blender add ons should be "free" for downloading and the authors should gain a proportional part of donations, based upon the number of downloads (i.e. based upon their popularity). I mean, it's pretty unfair to exploit a free 3D software like Blender to sell paid add ons, don't you think?
@@pile333 yeah it sucks big time. I used Facebuilder as hobby, so I had to use the free beta version. Until a few days ago when I tried to load it into the latest Blender and BAM, suddenly it stops working and prompts you to download the latest one. I was devastated
@@pakilla4578 That's not fair. Once again, you advertise your own product for free by exploiting an open source software like Blender? Definitely unfair. In the long run this could kill Blender as we know it.
@@pile333 Well, it's up to you to check the license terms.
Its fairly expensive tho :/, i really liked the time using it but i don't use it as often to buy it, it is worth it tho
I am genuinely curious as to how the math behind the whole face generation and texture aligning perfectly works. What kind of math even works here?
I would like to know that too!
Having played with it for an hour, and being a computer engineer here is my guess on how this works:
1. There is a generic face model
2. There is a face recognition algorithm. There are many ways to do this, (here is a good computerphile video about one method th-cam.com/video/uEJ71VlUmMQ/w-d-xo.html)
3. The result of a face recognition algorithm are several key-points (like eye position, nose position ect., they call them pins in the plugin), and in this case an estimated camera position
Each of the face models vertices is assigned to one or several key points by weights, (similarly how vertices are assigned to bones in skeletal animation)
4. You use the key-points and the camera position to calculate 3d-coordinates of each key-point for each of the photos
5. When all is done you perform an optimization with e.g. a least square optimizer to give you the final 3d-coordinates for the key-points
6. You deform the generic face model according to the weights assigned to each of the key-points
As for the texture generation:
Now you have the final geometry and orientation of the face and camera position for each of the photos and you have a UV-Mapping for the generic face model created in before.
1. For each of the pictures, project the visible geometry onto the photo
2. After projection you bake into a new image using the UV-Mapping
3. You blend the different pictures into one single texture. You may evaluate the quality of each visible polygon by calculating to what degree it is facing the camera or other criteria. Best quality results in that picture having most impact during blending.
@@powertomato thank you, this was very informative! Could you elaborate on how the key points are calculated and assigned the base face model verts though? Seems a tad too complicated, since there are many verts to choose from
Blender secerets - Auto Lipsync with Blender 2.9 ???
But isn't is paid
it expires after 15 days and you need to purchase
$399…..............................!!!!!!!!!
How much?????
not Enough
Isn't there a free AI that does this?
To be honest, I am not sure this addon has production value. For character modelling and texturing, you probably have different base mesh with different topology meaning after you use this addon, you still have to do retopo and texture projection. Also, you need a full body not only a head to work with. You can't have only a head in your scene...
Well, I see what you mean but you can often definitely get away with a separate head model that is not attached to a body. But yes, it would be nice if that was an option for sure!
500 Dollars!
This gave me terrible results for a 3D print. The person I tried this with had a very pronounced chin and a very specific nose-form. Nothing showed up in the geometry. So I guess this is just a generic model that is transformed a bit by the photos. Quick results and for generic looking people in quick shots gives really quick results, but nothing that would withstand close inspection.
Paid-per-month/year addon with a core installation and Internet connection required is very offensive to Blender and Hobbyists, so please don't advertise it.
thank you but this face builder is crap
Why's that?
@@SearchDenied The results definitely aren't accurate because it merely warps a base mesh to fit to the reference images. It does'nt have the neccesary details for a highly customized facemodel.
@@MultiMirs Yes and as a base mesh it works really great. So I really don't get the hate
@@SearchDenied I think it's because people are expecting amazing results with minimal work.
@@SearchDenied it just make a basic face model without any detail and its not even look like model
