In this video, I show how to set up AOV’s like Z depth and ambient occlusion passes, as well as how to create light groups to create useful render passes with Arnold in Maya. After that, I show how you can combine these render passes in Photoshop and use some filters and adjustment layers to make your 3d renders shine, as they should!

Render passes used:
- Z depth
- AmbientOcclusion (using Arnold’s AiAmbient Occlusion material)
- Mask (using AiFlat)
- ID
-Beauty (one for each light)
- Diffuse (direct/indirect)
- Specular (direct/indirect)
Creating these render passes gives you a lot of control in Photoshop and allows you to get the most out of your 3d models. Especially the Camera Raw filter is a fantastic tool to experiment with. There are a ton of cool presets to try out for inspiration and then there is a ton of other settings to experiment with. There are a lot of basic functions like level and HSV adjustments, as well as sharpen, texture, and vibrance to name a few. I find especially the Split-toning super fun to experiment with different color schemes. If you watch Transformers or the Island (2007) you will see this effect and I think if used properly it makes for stunning, very cinematic visuals.
I hope this video was helpful and you create some awesome renders. Feel free to reach out on my artstation (artstation.com/lukaskut/) or youtube if you would like to share results or leave a comment if you have a question, as I usually try to get back to every question.
