Hey sorry guys, I made a bit of a mistake in this video by not showing how to save the passes out. Essentially you DON'T want to do the compositing in your 3D scene but rather render your 3D directly to "OpenEXR Multi Layer" format (in the output settings). If you're not using Cryptomatte then you can set it to "Float (Half)" Then you would do your compositing in another scene or blender file and bring your render in to the comp using Image nodes rather than the Render Layer nodes. The Image nodes will have all the same pass outputs as long as you render OpenEXR MultiLayer from your 3D scene. I will do another video to explain but I'm not going to get a chance until next week.
Thanks for clarifying that! I've done that mistake in the past and my initial render got rendered twice (first from the main file output and then from the file output in the compositor)
alright, if you could now tell me which node I use to add in the shadow layer then everything's perfect and just a little side question: is it possible to use the denoise node on just the shadow layer or will that break things? because I made a teddy bear with hair particles and the shadow's are a bit too noisy in my opinion but when I add the denoise node to the whole image it treats all the hair like noise and blurs it to the point where I could have just used a flat surface. then I remembered you had this tutorial about render passes so I figured I might ask you about it

Hey guys, hope you enjoy my latest tutorial. This was a request from a friend who's learning Blender and he couldn't find much info on render passes. Is there anything you're struggling with in Blender that you haven't been able to find much info on? Let me know in the comments and and I'll look into doing a video about it.

One thing you didn’t mention that’s super important is that to save passes to a file you have to use OpenEXR multilayer, otherwise all the pass info will be lost as soon as you close Blender.
Hey Dylan, really good tutorial - thank you! I'm still struggling with the comping of those passes in Fusion. Unfortunately I can't recreate the look of the beauty pass and apparently the alpha channel seems to get lost during export (channel is ticked in blender and in fusion as alpha selected, but in fusion it's simply black). Sorry for this somewhat vague question. Maybe you got some tips on hand :)
I've watched a ton of videos on this subject but yours is the first that really showed me how to get control of those damn nodes and all the spaghetti!
I really appreciate this tutorial especially for the part when you mix passes with cryptomatte node! Hope I didn't duplicate anybody's comment. Just two tips: 1. You can save this setup in your startup file so that you don't have to repeat all these steps each time you do a project for a client, or save it in a file and append it (after enabling all the passes you need in the settings). 2. If your render takes 3 days to complete, you can save the output file as an EXR and later edit this file. Or enable the "save temporary render" switch (if I'm not wrong) in render preferences, in order to force blender to save them automatically as .exr: handy with animations...
This is a very informative video. I would be interested in a follow-up video about saving each pass as image files and how to put them together in programs like Gimp, Photoshop and After Effects.
It would be great if you shot a video about shader nodes and working with them, because there are few videos on RUclips that explain how to work with them, how to compose them correctly. Or explain all the mix shader modes. Thank you for your awesome content!
Mind blown. I'm more of a modeler but I've been meaning to get into rendering a bit deeper. Your tutorial has really opened my eyes to Render Passes...Thanks!
Just want to say THANK YOU for taking the time to make this video. After watching this, I will always render out passes. So much flexibility for the composite stage.
Thank you for putting this up, especially pointing out the hotkeys and basic mouse gestures to do the small stuff in the node editor. As a blender noob here, I appreciate those comments.
Thanks so much for the straight forward explanation and demonstration of purpose. I've been looking at the render passes section for years wondering what to really use it for and just ignoring it.
First video I’m seeing of yours. I really appreciate you sharing your knowledge. Good explanation abd great example of how to make changes and what the gotchas might be. I’ll be following.
I believe this is one of the most informative videos on blender, Thank you for sharing the knowledge, honestly, I didn't figure out till the very end of the video why all of this deconstruction and reconstruction, but the cryptomatt is really worth it... still the benefits are most for videos, images can be fixed in image editors. The only drawback is that mixing to be done but it worth saving the render time and electricity. Thank you.
I will go the Ian Hubert lazy way and simply change the color of the ball inside the material editor. x)))))))) Very good tuts though I have to say. You have clarity in your explanations it's awesome to follow your tuts because of that since you don't just skip over details yet you keep adding side hints which are often overlooked.
Really insightful mate. Thanks! I've worked with Blender for years now and render passes is one of those areas I've not done too much with. The odd bit of glare on lights, fog, or adjustments that could be done in most decent image editors. This is a whole new dimension though. Very useful indeed.
This was a fantastic video thank you so much. I always had trouble with fog glow on emission objects but now with the emission pass I'll be able to hone in on my craft. Cheers mate!
Fantastic tut. everything you wanted to know about passes but were afraid to ask coz you thought everyone was smarter than you.......except this guy really is smart.......so watch and pay attention
One of the developers was asked about this at the Blender Conference and he was saying because of the way Eevee works splitting out stuff like specular, diffuse etc is not straightforward. I just wish they'd hurry up and add object motion blur!
Hey Dylan, thanks for the great content! I think one of the biggest things I struggle with is UV's. I worked through your moving image video and thought it was awesome, but if you could produce a video that takes a thorough look at UV's and projection methods, I know I would appreciate it!
Auto-liked at the Cryptomatte part) P.S. "Gallop around Europe" about simulation types (fire, smoke, fluid and etc), force fields and particle/hair system - can be good idea for a series "simply about hard things". Touching curves also appreciated)
Theres a custom build with them in but they don't support splitting the light pass into diffuse/glossy etc yet. I'm guessing the patch should make it into 2.82 or 83
Thanks! The old Object Index and Material Index passes don't support anti-aliasing or motion blur and have essentially been replaced by cryptomatte. I wouldn't be surprised if they are removed from a future version of Blender.
Wow! I had no idea this kind of stuff was available. Great stuff. Can't wait to see what other great tuts you have or will do so I subscribed. As a suggestion, I have been having the worst time rendering fire in Eevee with Film transparency enabled for a Alpha background. Any light you can shed there would be fantastic!
Awesome video. Would like to see your thoughts on how to export/save the passes to disk and then reload them into compositor from separate files. As it stands, those passes would only be in memory right after a render. Or am I missing something?
If you set your render output to OpenEXR Multilayer then the passes get saved into that. At the moment separating them out into separate files is a bit of a pain (you need to use the "File Output" node in the compositor and hook them all up) But I'm working on making that process A LOT easier.
in your professional work do you use blender or after effects for composition? im not sure what option its better. great information here, the cryptomatte can be very useful for future projects
I use Nuke mostly, or sometimes either Digital Fusion or Blender compositor for simple stuff. After Effects is great for design/motion graphics but not so good for visual effects and 3D compositing.
Good tutor, thanks! I have some issues with combining passes in figma and photoshop because of different color spaces I think. Would you please make some sort of tutor video about how to post process blender passes in other soft )
hey great video - was just wondering is there way to render out the normal (digital multicoloured) render pass in layout mode? would like to easily get this effect!
This is a great video, thank you for sharing. Maybe you can answer a situation I continuously run into. When previewing each of my passes before export, Ambient Occlusion is either true white or true black. It does not appear to have any of the grey values that I really need from an Ambient Occlusion pass. It currently looks more like a mask between objects and world / transparent. This issue does not appear to be associated to the Ambient Occlusion material node; when adding, it has no effects to the Ambient Occlusion pass and only adds to the material itself. The AO pass remains true white / black. What am I doing wrong here?
Hey Dylan, is it possible to render these passes individually? So that I can remake the final render without the Combined layer, as you can imagine I am asking this to see if I can create a shot with Cycles, break it down in passes and render out an animation.
If you mean render each pass into it's own file rather than all into the multilayer exr then it is possible but a bit annoying to set up. In the compositor you need to connect each pass into a "File Output" node. You can set where each pass is saved in this node
If you export a multiexr with those options checked it should include all those ones directly, isn't it? oh, and thanks for all your tuts... and for not using annoying music, sound effects and colorfull presentations... just information :)
Yeah if you set the output to multi layer exr then you will get all the passes in the file. You would then do your comping in a separate scene or blend file or some other software.
Is there any reason you would NOT enable render passes? As I understand they don't significantly increase render time. P.S. Brilliant and thoughtful demonstration.
Hey Dylan - Great Tut. When you close a blender file and re-open, the passes are gone. Can you save them (preferably in the .blend) so that you always have the passes and cryptos for when the client wants that pink ball :)
