Transparent textures support #8
Description
The engine appears to have no support for textures with transparent pixels. First they just displayed as black cubes. I got transparency to work by making a simple modification to the chunk shader and adding alpha support.
Now it causes huge glitches, culling blocks behind itself:
Apparently, opaque and transparent blocks should be rendered separately and transparent blocks shouldn't affect depth. But I couldn't find a way to determine if a block being rendered is transparent. Is it possible to implement adequate transparency handling without significant changes to the entire rendering logic?
