Haha magic! ;) I actually just drag over a node to select it and then press 1 to set the viewer on it. Just a habbit. Because I use a wacom instead of a mouse sometimes clicking a node moves it slightly and I like my scripts to be very straight!
hi sir .. how i can export my 3D object with aovs without rendering from blender to nuke. sorry for my english , iknow its so hard to explain that . but i mean ..iwant to put my 3d object into nuke for fully control , not with render . becoz if it render, will show just image or video of my 3d object, not like a fully 3D object.. so how i can export my 3d object with aovs from blender.. any idea sir
You can export it an as an alembic which is a 3D format and then you can bring it into nuke. But it won't have AOVs. You can only get AOVs from rendering. The scanline render node has the option to output some like the depth channel but it's not as many as rendering from blender. Hope that helps!
I am running into a bizarre issue where the nuke isn't picking up an alpha channel from my render. The render shows on transparent in the blender render window, but when I bring the exr into nuke there is no alpha layer.
@@AlfieVaughan I am using the same file output setup you have. I found the alpha layer. It shows up as "alpha_extra" in nuke and I have to shuffle it back into the image.
Awesome tutorial! One of the few high quality Nuke tutorials on TH-cam imo. I do have one question, how did you block out the bushes in the final shot (the tank is behind the bushes)? I just started using Nuke a few days ago, so I'm new to the whole process.
Thanks a lot! It's really simple. Just create a roto node and draw around the bushes. Then on the right side of the merge node is a mask input. Plug the roto into that and add an invert node between them which makes the tank show everywhere except inside the roto shapes you draw :)
Thanks! You can get Nuke non-commercial for free if you want to try it out. It's missing a couple of the advanced features but for the most part it's the same and great for having a try in :)
What do you want to know? It's exactly the same software but the output resolution is limited to 1080p and you can't use third party gizmos I don't think. And there's a few nodes like the write and read geo nodes that are disabled. I'm not really sure how a tutorial using it would be any different to this. Maybe I can answer any questions you have?
Hey Alfie thanks for the tutorial. Do you think you could please explain how to go about creating overscan in Blender to account for the lens distortion?
Hey! There's an overscan add-on for blender that you have to install that allows you to add an overscan percentage in the render settings. If you just Google blender overscan add-on it'll come up
I had the apprentice full license version in this but you can do most of it in non commercial. But yes the write geo node is disabled in non commercial
Hi, trying to switch from after effects to nuke here. I had an issue in AE where the filmic color space is very poorly supported when bringing in openexr sequence from blender. Is that an issue in nuke?
Filmic doesn't really work outside of blender. It's fairly proprietary. I work in ACES across both as it's properly supported and it works great. I'd recommend doing the same or just standard sRGB
Thanks! I just select the vectors from blender in the "UV channels" drop down and then turn up the amount and set blur UV to either uniform on linear depending on what I think looks better :)
@@AlfieVaughan Thank's for the replies, but you have to render 3 time to get 3 layer rendered.. isn't it?(i Honestly don't know that need 3 time rendering)
@@lsingleplayerl yes you're right but I find it saves time in the long run having it split up. It also means you can render them at different samples which can improve render time. For example, I usually render shadows at a much lower sample rate than the main beauty because I usually blur them in comp anyway. It's down to personal preference really!
@@AlfieVaughan Oh i see shadow catcher need different render layer. I didn't know that. Again thank's for Great video and Comment! This is really helped a lot!
I think there's an add-on for importing SketchUp files. You can't do 3dsMax files as they are but if you export then from 3dsMax as an alembic or something that's more universal then you can bring them into blender
Hi! I have question - i rendering picture with denoise. And will need to compositing in Nuke. But my compositing artist say what Nuke cant understand blender's denoiser. If I rendering without denoiser, picture will coll in 750 samples, if with denoiser - enough 200-150 samples. How to rendering in blender with denoiser if Nuke cannot work with noisy pass? I see your denoise in tutorial si ON, but havent see noisy pass.
If it's an actual plugin you'll probably have to actually install it with a setup file or something (it varies from plugin to plugin...) If it's a gizmo you should just be able to drop it straight into your .nuke folder. You might have to add it to your menu.py file as well so you can see it in Nuke. If so it will probably come with a text file to add to your original file!
Not really. It definitely helps and is very useful. Most 3d artists know some python I think but it's less common for 2d. I know a tiny bit just to get by building tools etc in nuke but I know hardly any
Have you set the depth pass to use the correct channel? Nuke expects it to be called depth.Z or something but it comes out of blender with different names depending on what you do. Either rename it in blender or select the depth channel it's actually in within the ZDefocus node :)
@@AlfieVaughan Yeah, I tried that. I'm use to doing this with Arnold and Renderman. I just can't get it to work with Blender for some reason. I'm on 10.4 but I doubt the Nuke version changes anything.
maybe it works with a shuffleCopy. If you've rendered and imported the zPass, you could create a new Zpass layer in the shuffleCopy. Like he did on 14:45. You link your zPass on input 2 and in the shuffleCopy, on the right column which says: 'input "none"', you put none on your zPass. Where he put layername 'P', you create your own custom-name for the ZPass. Now you put the ZDefocus under the shuffleCopy. In the ZDefocus you put 'depth channel' on your 'custom-name' and you're set. It's a while ago I've tried something like this, but I think it would work :p
I'd like to but you can only do it in the fully licensed version of nuke annoyingly. The best way is using a write geo node and exporting everything as an alembic. Then you can import that into blender and you can do the same from blender to nuke. But the write geo only works in the paid license of nuke. That's the easiest way I've found so far :)
@@AlfieVaughan Have you figured out how to get empties to transfer over? I can get Cameras and geo, but for some reason blender empties won't import into nuke. I want to use empties as a way to track particle emitters without importing geo
That's odd. It usually works for me. Are you using an alembic? Maybe only certain types work. Try the plain axis empty. Thats always worked for me. Failing that you can export 3D objects from nuke as a .Chan file even from non commercial. Give that a try too
No problem! Yeah I just added a single driver to the X rotation. Then in the curve editor under the driver modifiers you set it to translate channel and make the object the rig (the cube in this video). Then when you move the cube, it rotates the wheel :) if you look up blender wheel driver or something there's lots of tutorials
great tutorial, but i am new to nuke still trying to understand some basics. i wish you do a beginner tutorial on how you will track and export data to blender for beginners that will be cool.
Thanks! I'm glad you like it. It's really really easy. I probably won't do a tutorial on it but all you have to do is do your 3D camera track in nuke (there's loads of tutorials for that!) And then you use a writeGeo node in nuke to export the camera to blender :)
With the camera selected go to file, export and select alembic or fbx. Both of these formats supoort animation data. Then in nuke use a read geo node to read it in :)
Hi, thanks for the excellent explanation of how Passing works in Blenedr. I just want to note that after copying your script, I noticed a small typo. All Backdrop node in Glossy have same name "Glossy Direct" but apparently should be called "Glossy Indirect" and "Glossy Сolor". This is not a big problem, I just decided that after such a great explanation, someone might be confused if they see it in your script. In general, I subscribed to you with great pleasure and will follow that channel.
Thanks for pointing that out! This video is quite old and I no longer use this method. I have a newer video about render passes you might enjoy :) it's much better and more accurate information

I am running into a bizarre issue where the nuke isn't picking up an alpha channel from my render. The render shows on transparent in the blender render window, but when I bring the exr into nuke there is no alpha layer.
Are you definitely rendering rgba and not just RGB?
@@AlfieVaughan I am using the same file output setup you have. I found the alpha layer. It shows up as "alpha_extra" in nuke and I have to shuffle it back into the image.
Oh that's strange. If you rename it to rgba like I have it should work. Not sure why it isn't for you, sorry
@@AlfieVaughan I am also denoising the rgba which could be messing it up
It shouldn't be. I denoise it too. Maybe put a photo of your setup in the discord channel and we can help
