hi, sorry to be bothering, I asked that question some days ago on the pd list, maybe the gem-dev is the better place to ask. I am referring to a mail from the summer between cyrille and chris, but can't find it anymore.
I am trying to get more multitexture glsl stuff working. the problem I am having right now is that I don't know how to pass the rectangle coords of the second texture to the glsl program. in the example I got, it looks like only the coords of one texture are used... vec4 color = texture2DRect(MyTex, texcoord1); vec4 color2 = texture2DRect(MyTex1, texcoord1);
but in another shader I got
texcoord0 = vec2(gl_TextureMatrix[0] * gl_MultiTexCoord0); texcoord1 = vec2(gl_TextureMatrix[1] * gl_MultiTexCoord1);
and that does not work.
I wondered how glsl knows the size of the first texture and I tried to have both textures in one render chain, but that did not work. in the mail I mentioned above read that I can send a message to the glsl program to tell it the coords. how do I do that?
or should this work, and I am only using an old GEM version (0.91-cvs from july29)
thanks, marius.
