V-Ray AOVs (Render Elements/Passes) - Razor Crest VFX Lecture 07

An introduction to V-Ray AOVs (Render Elements or Render Passes). We'll also do a quick composite to rebuild the beauty in After Effects. Other AOVs, such as cryptomatte, depth, and glare will be covered in future lectures of this series. If you're using Maya 2022 and above with After Effects, make sure to grab the OpenColorIO plugin to view ACEScg renders properly.
These lectures were originally built for a college VFX class that I teach, taking students from beginner to intermediate level. Over the course of this 9-hour course, brush up on PBR surfacing with UDIMs, learn about lighting, AOVs, render layers, batch and sequence rendering, EXR compositing, and ACEScg with Maya, V-Ray, and After Effects.

It hurt me to have to delete the composition after it took me 2 hours to do it.

Practice makes perfect haha

I don't quite understand why the GI layer is placed at the bottom. According to the normal synthesis process, shouldn't the diffuse layer be placed at the bottom?

[@ericsure8625]

Thank you master

[@CGStirk]

In V-Ray, the GI AOV includes the diffuse. If you want to control the diffuse and the global illumination separately, you multiply the Diffuse AOV with the Raw GI (these layers go at the bottom). You can do the same with Diffuse and Raw Light instead of using the Lighting AOV, which already combines diffuse and just the direct light info.

@@CGStirk Very detailed answer, thank you master.

Man your channel is pure golden. Believe me! Weird that after months and months searching , just now you appeared to me! The RUclips algorithm is really weird and unfair! I hope more people can find you soon! God bless your kindness.

Thanks! Spread the word lol. I'm apparently terrible at marketing myself, but I know these videos are boring 😆

Thanks a lot for the knoled, So after this video i have a question, is there possible to render Beauty but without only a few AOV so i can control them in compositing?
For example in this Tut, if i want control only on reflections, so i do the render only with those passes toggled, instead of loading all of them.

[@CGStirk]

Thanks! It depends. For raw reflections, you can probably subtract that pass from the beauty and then add another copy as an additive pass to control just reflections. However, there can be complications with this approach depending on the pass and how you set it up.

[@Penetratore]

@@CGStirk Thanks! So if i want to have control even on a few AOV, is best to recreate the beauty anyway with all the others too?

[@CGStirk]

@@Penetratore Yes, generally speaking. However, you can use the V-Ray Frame Buffer Composite feature to do all your simple compositing directly there if you want to minimize post work. I don't have a video on it, but I can provide help via Discord.
