Hi Ge,
Which model are you loading? If it has no texture coordinates and
texture assigned you won't see much ;-)
Also you can try to remove the ifdef for the textures to see if it has
to do anything with the composition. I'm successfully using the
shadercomposition from the very beginning and haven't found any related
issues.
Cheers
Sebastian
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.
