Hi, I was wondering what the fastest way to update textures every frame would be? Let's say if you had a 3d model and could "draw" other bitmaps on it's faces. The drawn bitmaps would be composited on the original texture bitmaps and would be updating every frame.
I've got this working in broomstick already using BitmapMaterial.updateTexture() but slows down when multiple textures are being updated and they are 1024x1024. This would eventually run on mobiles so I'm trying to get things as fast as possible. Any ideas if this be possible say in pixel bender? Is there a way to composite two textures in a shader, so u would upload textures + "drawable" textures to the gpu to begin with, and then only pass x/y coords + drawable texture id as parameters and let the gpu update the texture accordingly? Cheers, Jamie
