[GEM-dev] gl_MultiTexCoord1

[marius schebella]

hi (chris),
I know that I am bothering you, but I think you (chris) are the only one 
who can help with the MultiTexture stuff and therefore I send another mail.
I don't know how to get gl_MultiTexCoord1 and higher working. I cannot 
reference glsl to read from any other than gl_MultiTexCoord0. I looked 
into gem code for glsl_vertex and glsl_program, and did not find 
something which looks releated to multitextures.
then I looked into GemShape.cpp and rectangle.cpp and found a variable 
curCoord. and a section in rectangle that is related to that and 
commented out. I am (still) no C programmer and don't know the history 
of gem (why parts are commented out...?), but it seems that these two 
things, in connection with SetVertex(GemState* state,float x, float y, 
float z, float tx, float ty,int curCoord) could be part of the problem.
thanks,
marius.
