// OsgEarth shader code function
void Compute_FS(inout vec4 color)
// Set the base texture (this could be the terrain texture as well).
color = texture(BaseTexSampler, BaseTexCoords.st);
color.a = 1;
This gets ignored if I used texture unit 0. I have to switch to texture unit 1 in order for it to work. How do I override texture unit 0?
