Interesting thought; with enough high detail geo you could bake texture data right into the vertex colors.
After running a small scale test I found that was no noticeable loss in quality and there was a save of 6MB~ in file size decrease and 99 shader instructions on an asset that has a quarter of a milion tris with diffuse and spec baked in vs texture samples (DIFF/SPEC/NORM at 4K).
And there are other things to explore like channel packing, stylized rendering, and perhaps even VR when support comes around.
I’m very much interested to see how VR will benefit from some mindful use of these new systems and techniques that will stem from them.
I wanna know what other people think, viable? or Nah? predictions for VR?
