[osg-users] 3.4.0 osgshadercomposition texture issue

Hi,

I compiled OSG 3.4.0 from source and ran osgviewer to load the following models: cessna, cow, cube_mapped_torus. All models render correctly.

I also ran osgshadercomposition, which renders five instances of each model mentioned above. However, for each run, the last three instances lack texture.

1) I just want to ask if anyone has seen this symptom and if there's a work around. Hopefully, it is an environment issue that's easy to fix.

2) My own debugging indicates that

texcoord = gl_MultiTexCoord0.xy;

may be assigning 0 to texcoord.

3) I also searched a little bit and invoked

State::setUseModelViewAndProjectionUniform()
State::setUseVertexAttributeAliasing()

both to true. The base color seems to switch from white to blue. But the texture is still missing.

Any help is greatly appreciated.
