P0-A6: Part 698: UDIM, Grass Shadows

I have done some more experimentation with UDIM in unity, and it seems that in the latest version, UDIM actually works.

In previous versions of Unity, I was unable to ge UDIM support working, but in 2019.3, I was able to add a single object textured with 8 different textures.

I split the model up by polygon ID, unwrapped it with each ID on a different UV tile, and then exported it to Substance Painter and Textured it as usual.

I then exported the texture maps into unity, and applied each map to the object, and it worked perfectly.

I don’t know if I missed something in the release notes, but it seems that UDIM support now exists natively in Unity.

I intend to use this for texturing large interior objects.

The next goal is to reduce the shadow strength for the grass. I want to keep the scene shadows as strong as they are, but reduce the effects of shadows on the grass only.
