This is an example of great teaching, actually showing the problems that can happen, why they happen, with a solution for them, very well explained, this is why so many tutorials on the internet just have comments that say "when i click this button nothing happens for me" and i think the reason is most of these tutorials dont show what could go wrong in the process
Been digging deep into blender compositing the past couple days but it seems like a barely covered topic and last night I said out loud "watch someone is going to upload a tutorial soon just keep digging".👀 Need a masterclass.
I think after watching 100's of tuts over the last year or so, your vids are some of the best. I took the full course on CGBoost and it's totally worth it. I was ignorantly fighting to render a giant scene all at once so the render layers was a critical step forward for me. Thank you.
seems like an interesting video. Still 2 minutes in but my question is why use blender compositor (pretty slow and buggy) when you can use Nuke, AE, Fusion. still love the video but im just confused about this
Hey there, thank you! CGBoost focuses on using Blender, so we aim at staying in it as much as we can :-) Those tools you mentioned are great for compositing, but would be a deviation from our CGB pipeline :-) Also, this is from Master 3D Environments course and I wanted to make it Blender-only.
Good question. I think personally learning how to compost in a free tool like blender is an excellent place to start. Not everyone can afford tools like AE or fusion and the skills you learn in blender can be transferred.
Though nuke, after effects and fusion are really convenient and have a lot more features than blender. It's more of an affordable thing. Most people can't buy programs
Its just a matter of the price… Apart from Fusion you have to spend quite some money on the Nuke or AE, in addition I think Blender can be a great tool.
this is solid advice. Thank you! And I love the final cut from the composited mountain to the course page with the same image! Only the indiana Jones Intro can do it better :)
I guess this depends on whether you have AE and your level of knowledge of AE. There are also other compositing options like Nuke but unlike Blender they are not free. As of free options there's the free version of DaVinci Resolve that also allows for compositing.
ALL of the improper methodologies I can think of are being taught here. Do yourself a favour and skip CG Boost unless there are no other alternitives. I can't speak for the quality of their paid contents though so do so at your own discression.
You have the liberty to not follow the our courses if you do not like them. Also, if your work experience is superior, feel free to create the course with the proper methodology. ~Egon
@@cgboost While I appreciate your dedicated contribution to public knowledge, it is important to realise that even these free tutorials come at a cost of the viewers, especially when the wrong methodologies are being conducted. Any experienced user may not learn much from this tutorial, and as an introductory video, it might even hinder the progress of those new to blender compositing. To correct some of the mistakes regarding this video: Your convoluted use of view layers cannot be justified in this particular blender scene. For example, the foreground dust, or the sky, can both be distinguished from other elements by a combination of denoised depth, alpha, and cryptomatte passes. Excessive use of view layers where memory is not a concern can increase render times and manual labour, and makes the workflow prone to mistakes. Unless you're compositing straight out of the render buffer, compositing with any sort of color grading in mind requires the source material to be in a high fidelity format, and in most cases involving blender, need to be in linear Rec. 709. Using 16 bit PNG with filmic “standard” is extremely ill-advised. Use multilayered EXR so that there will be one file output only, which would output all passes of each render layer. Using only an RGB curve is also cumbersome and hard to keep track of, and it is best to leave it only for fine-tuning or a particular look that can’t be achieved with ASC-CDL wheels. It is always advisable to use a viewer window instead of the backdrop so that you can keep an eye on the scopes when needed. These are only some of your most fatal mistakes in doing compositing work within blender, and demonstrate your lack of understanding of this topic. As it is beyond apparent from your video that you intend to remain in the business of monetizing online tutorials, I urge you to make an attempt at finding out as much as possible about the proper procedures of compositing. Otherwise, you will only be contributing negatively to the blender community.
“i sometimes like to go with what’s nice, rather than what’s correct. i mean, uh, when it comes to compositing… not in real life, of course,” (clears throat) “uh, so…” : masterful subtlety of implication with emphasis. fr i lol’d. this level of comedic class can’t be taught and Martin exemplifies it seamlessly. also this is a super comprehensive vid that is demystifying a lot of the compositing process for me, a novice/intermediate Blender user using lots of open source apps for independent sketch comedy musical and atmospheric weirdness
What a great tutorial!!! Actually dust does not remove light from the point of view of the observer, IF the light source is positioned on a certain angle. Then the particles are lighted. So you did it right.
I've been lowkey looking for a concise explanation of how to use the Render Layers/View Layer, and here I've found it in a Compositing tutorial. Now all I need to find is a similarly simple explanation of some use case scenarios for the Scenes Tab (dropdown menu?) and that would scratch an Inquisitive Itch. Side Note: does the Colour Management (Filmic/Standard) affect Compositing in any way?
I used scenes once to have a machine in the foreground and a blurred air flow looking graphic behind it. It was easier to blur particle system bubbles into what looked like air flow than to create an actual air flow simulation. So the front scene has foreground elements and the background seen had the blue. After watching this though I think it could be accomplished with Render layers. Maybe scenes are like in a movie when you cut to a new location but scenes let’s you keep all the elements in your blended file vs starting a new one and trying to keep them consistent. I think the asset viewer will help with that in the future though. Okay done rambling.
@@chuckpenzone3407 Yes exactly, it is more to have mutlible scenes in one file. So in onie scene you have a forest and a cabin in that forest but in the next scene you can cut to inside that cabin. It splits the complexity a bit and makes it a little easier when compositing those scenes. Tho I never use it, only seen teams that use it or people that want to make a short.
Yeah great, i had many problem with that "convert pre multiplied" in the alpha over node, i have a simple scene and i want to composite some fire flies and what happen is that the edge of each individual fire flies look weird and when checked that convert pre multiplied they look good but I loose the glow of the flies!! Please help me out.
This vid is great, quick question, my scene is using a big cube with a volume scatter for a fog effect, how would i go about rendering and compositing that
Great timing, thank you, been diving into the compositor alot latley, and making my way through the environment course, all in all making my visuals next level fo sure !!! ;)
Why did you render twice? Once after adding the file output nodes and once after tweaking the output properties settings from the side panel? Why is it double the amount of work? Can we not directly render the layers after we create different layers and save the image sequences through File output node by specifying the folder name right there in the File output node itself at a single time? Why is that you went ahead and tweaked some output properties settings again in the side panel and hit render again? Made me super confused anyway. Hope you can reply
Hi, going through this now. WHen I set up the compositor and render, it saves files to the mountains, dust and sky layers, but no file is saved in the base folder. Any idea what might be causing this? Thanks! I am on Blender 4.0.
Hi, what do you mean exactly? There are many ways you can isolate the background. For example, you can render it on a separate view layer and then combine it to the rest in compositor. This should work with any kind of backgrounds including HDRIs. ~ Masha
I am getting extreemly annoyed with Blender. I have time lapse photography that I have sequenced. The sequence doesn't transfer across to damn compositing, which is always empty!
This is an old video but still is really cool! But could you please tell if something has changed within these two years? Isn't now more productive to composite using passes, cryptomatte and EXR?
I used davinci resolve for the color correction and composition but damn, this brings the believability of my vfx shots up like 500 %. I’m not going to lie my shots sucked before but now they actually look some what nice. Thank you so much Im your newest sub now
Person A: "Oh, compositing is a waste of time." Person B: "Oh, yeah. Not to mention most likely how Id Software handled...just about every Doom game in a similar fashion to composition." Person C: "?"
If anyone is having trouble trying to get their base layer to render, don't worry. You probably have it right and the only reason your aren't see it is because you aren't rending it as a animation. You need to render it as a animation for it to auto save.
Hello, my file output nodes (6 total) appear to be set up properly, but my render layers still do not appear to show up in there selected base path outputs. From what I can gather is the output nodes are rendering and saving the final frame of each render layer, but only in blender. What does get saved and outputted into a folder is the output path from the side bar settings. Is there a way to override the sidebar so my renders only happen via the file output nodes? Each time I have rendered as a png alpha animation. Rather stumped
@@emerysheldon9006 Would you mind sending me a couple of screen shots? That would help me figure out what the problem is. You can send them to my email.
@@cgboost your header buttons are floating without a gray background behind them. My header is opaque and the same color as the rest of the menus top and bottom.
hi, thanks for the tutorial, although i faced a problem when i check the denoising data box in the passes tab it doesn't want to update in the render layers in compositing, i need help please, because i couldn't find a solution for it. although it works fine in new blender project it can be updated but in my current one it doesn't want to.
What's the best workflow if I prefer to finalize my composites in After Effects? Do you still render multiple times? And would you even touch the compositor in Blender?
hi, thanks for the question. If you want to composite the scene inside after effects, you still export multiple PNG layers but then instead of uploading them to Blender trow them directly to AE. touching or not Blender compositor in this case is up to you. If there is any function of compositor that helps you more then AE, you might use it for that and the rest you do in AE. ~ Masha
Hello! Great tutorial! But i have a question. Why worry about denoising a render layer in compositing when you can select the 'denoise' checkbox for the render?
It used to be that you couldn't select this denoise option in the REnder menu and had to do it through compositor. Nowadays, it works both ways, I just got used to the older one 🙂
the Issue I have with compositing is that despite working in or with 3D enviroment you don't get the ability to use your assets elsewhere ... like in game engine ... or I mean you could bake the texture and use it ... but ... Im just mindblown about how good displacements look especially for hilly terrains ... the scene setup just wow ... nice I can't hate it Im just weirded out
Once the project gets really big and you want to change just some part of it you realize the benefits of having a good structure and everything broken down to small chunks. With smaller projects made by just 1 man a 'one take' approach might work sometimes but that doesn't scale really well :).
This was perfect. I do mostly animation so I will try to use these tips and adapt them to motion shots. I thought single frame renders were easy - you showed me how awesome they can be
If it makes you feel better: it isn't necessarily wrong to layer over the dust elements using 'add'. Sandy dust in the air will reflect incoming light and scatter it, acting is a "passive emitter" of sorts. I think what you've intuitively noticed (it looks better) is actually correct. This phenomenon is not in opposition to the fact that dust in the air will block or filter light that passes though it. It's an anisotropic effect where the front of the dust looks brighter (light scattering back) and the backside of it will be darker (less light after filtering/scattering).
hi CG Boost :) if i render out an image sequenze to finaly a movie, why blender is so slow doing it? does blender also actualy render the image like 3d objects? becouse, if i render the same sequenze in sony vegas, its mutch faster
Hi, if youre using the same scene for rendering out your 3D scene and your Composition, it may be that you are rendering both. I suggest using a separate .blend file for the compositing.
For the vignette, you can set the resolution and scale values to automatically drive the ellipse size by an equation. then you can for example scale it by a value of around 0.93 to make it slightly smaller
Did I miss something? I’m trying to find a way to render a scene with w lot of high poly models in it but it’s way too much memory for my gpu. How do I render only certain objects to while keeping the shadows and reflections etc casting onto those objects?
That you do by using Render Toggles in the Outliner, you set various toggles for your Collections, for example Holdout to make everything on the collection transparent in the render, or Indirect, to make everything on the collection transparent, but retain its reflections and shadows...
PNGs only really natively support up to 16 bit colour depth whereas a format such as EXR can handle 32 bit colour depth which essentially means a smoother transition from darker to lighter values (and vice versa). There are other quality compromises with PNG but they are fairly minor for most uses. ~ Daniel
I'm a beginner so I can't understand that totally how you create this at the root. Some I understand but maximum not. So please give a tutorial for 1st to last begginers?
This is course about an advanced methods of creating environment, thus intermediate users tutorial. If it is for beginners the content would need to be deeply simplified. ~Egon
Using 2D and more 2D is a 3D software amounts to LYING to the viewer, who thinks he is getting a 3D picture. This shall be Punished with a downgrade in the number of cores you are allowed to use on your GPU.
Totally a noob question here, but is there a way to use an EXR file to transfer out the Render Layers to, say, Resolve or Fusion instead of staying in-house with Blender's compositor? I'm aware that you can render out the passes for the image as a whole, but the actual grouped layers; would you need to use multiple EXR files per scene, or can you have the grouped layers and their passes in one EXR file?
Hi, yes, if you render out an EXR file it will automatically store inside the file the different layers you created and the passes you selected in render properties. I personally tried it with my colleagues using nuke, and it worked pretty fine, so I guess it should be okay for any other compositing software. ~ Masha
