Arnold has been a default renderer plugin in maya since 2016. We can use it for many purpose in game asset creation.
- Arnold’s material aiambient occlusion can help you render AO to texture using a normal map
- Only Arnold 1.4.2 (no over 2.0) can render AO to texture using transparency.
- In order to render alpha, you need a camera (you can use LD_MayaToolbox, or write one to create a camera exactly the size of the plane). You can definitely bake alpha using maya transfer map function or xnormal, but you’ll get 2bit alpha with no anti-aliasing.
- In hair workflow, you can use it to render hair texture.
