<h1>Problem</h1>
Hello. I'm trying to share a Uniform Buffer among different programs. The problem is, that I have to query the layout - which is shared - at one point. I tried all possibilities, but it always return -1.
The specification tells me, that with the shared layout, the driver is not allowed to optimize and has toactivate the variables.
What did I miss?
<h1>Code</h1>
#version 420 core
layout(shared) uniform Camera {
mat4 camViewProj;
mat4 sunViewProj;
mat4 sunViewCoordProj;
};
out mat4 outVar;
void main()
{
//outVar = camViewProj;
}
I only get a valid index for "camViewProj" when I uncomment the section above.
To Query the indices, I used:
glGetProgramResourceIndex();
glGetUniformIndices();
