Hi, Thank you for digging :). Good observation, GL_DEPTH_TEST influences the z-buffer (of course you would say...). Actually, when accessing a depth texture in a shader in GLSL 1.2 if DEPTH_TEST is ON it has to be passed as a sampler(2D/Rect)Shadow else as a sampler(2D/Rect). This may help someone someday. Actually, I had just forgot to check my texture units (I thought I had, but I had just begun and not finished) and wrote z-buffer on a unit used transparent faces use. I didn't want to push it on the top of the topics, but I have to reply to any help.
