At my wishlist:
-
FX pipeline, with support for CgFX shaders and an easier system for managing render passes and postprocessing filters.
-
Native collada support
Combining those two we could get support for ColladaFX too, and people will be able to use tools like RenderMonkey or FX Composer to create shaders.
The texture nodes thing that you showed is also on my wishlist - we could extend TextureStage to have more modes like that, and input/output connections to other stages.
About deferred rendering - if I get the FX pipeline stuff done, implementing that will be a lot easier!
Oh, and I forgot one:
- Hardware geometry instancing
