Hello,
I've been wracking my brain all day on trying to figure out how to do this with
no clear examples found online.
I have this set of calls in my C++:
mGroupState = mBoundGeometry->getOrCreateStateSet();
mGroupState->getOrCreateUniform("BaseTexSampler",
osg::Uniform::SAMPLER_2D)->set(mBaseColor);
mGroupState->getOrCreateUniform("BaseWeight",
osg::Uniform::FLOAT)->set(mBaseWeight);
mGroupState->setTextureAttributeAndModes(BASE_TEXTURE_UNIT, mBaseColor,
osg::StateAttribute::ON);
I've bound this base texture to texture unit (BASE_TEXTURE_UNIT = 1).
Later in the code, I have this in another function if I create another layer
with another texture:
mGroupState->getOrCreateUniform("TexLayerSampler0",
osg::Uniform::SAMPLER_2D)->set(tex);
mGroupState->setTextureAttribute(BASE_TEXTURE_UNIT + 1, tex,
osg::StateAttribute::ON);
Where I've created a second texture and want it to reside in texture unit 2.
However, in my shader code when indexing the TexLayerSampler0, I only get base
texture.
finalColor = texture(TexLayerSampler0, LayeredTexCoords[0].st);
Which is wrong. I'm stil trying to figure out OpenGL and how it works along
with OSG so sorry for the inexperience.
