Re: [osg-users] Can't assign more than 7 texture matrices

Hi, i belive i solved this issue. I had to use: osg::Uniform* uniform = stateSet-getOrCreateUniform(matrices[0], osg::Uniform::FLOAT_MAT4); instead of: osg::Uniform* uniform = stateSet-getOrCreateUniform(matrices,

Re: [osg-users] Can't assign more than 7 texture matrices

Hi, i thought i could use the buildin variabled to save some uniforms. But i did'nt realize that they were limited. Well.. i tried to use uniform arrays but with very little sucess: I create my Uniform: ref_ptrUniform matrixArrayUniform = new Uniform(Uniform::FLOAT_MAT4,matrices,10);

[osg-users] Can't assign more than 7 texture matrices

Hi, i have a small problem. I want to access gl_TextureMatrix[8] within my Shader. As you can see i used a loop to setup 10 texture matrices: Code: for (int i = 0; i 10; i++) { stateSet-setTextureAttributeAndModes(i, texMat,

Re: [osg-users] Can't assign more than 7 texture matrices

Seems to be another ati related issue. I was able to reproduce this issue with pure opengl. :-\ Any suggestions on how i can handover multiple texture matrices to my shader? -- Read this topic online here: http://forum.openscenegraph.org/viewtopic.php?p=18366#18366

Re: [osg-users] Can't assign more than 7 texture matrices

I don't see the problem. Quoting from the GLSL 1.20 spec below, it looks to me like you're lucky you're even getting 2 matrices -- the minimum value for gl_MaxTextureCoords. You can't simply use a uniform? Paul Martz Skew Matrix Software LLC _http://www.skew-matrix.com_
