I finish my scene implementation, now can draw a scene complete with one draw call.
The previous error continue, not is the thickness because I fill the gaps between layer for mimic voxel rendering, really no gaps between layer now. but to certain ange the texture don't draw the borders complete. pehaps in opengl this not happen.
I try to advance in lighting, I read you code but not know about gm, I see you add normal information to the vertex..How work the illumination? You can say what file I need to read to see this?
