So, now I have erased all warnings, but it still does not work. How I mentioned before, could there be a problem with the texture Matrix (gl_TextureMatrix[1] in the vertex shader). How can I check, that the texture matrix is set up correctly in my main program? Btw turning on the debug level was helpful for erasing the warning, but I could not found any errors. Thanks
