Hello all!
I’m not sure I totally understand what I’m currently doing.
I’m trying to make one of our models displayable only with the “core”
profile (using 3.3, 4.2, etc.), I seem to be able to build OSG for that
(e.g., the code that is in ’OSG_GL_FIXED_FUNCTION_AVAILABLE’ defines is
correctly left out), and create contexts for 3.3+.
I’m using the osgsimplegl3 example as a basis, and one of the simple models
that we have here (converted to osgt for my tests).
Now, my test model contains stuff like “quads,” which I managed to remove
manually (for now, will fix that later), and it also contains attributes
like
osg::Material {
UniqueID 4
Name "default"
Ambient TRUE Front 0.50 0.50 0.50 1 Back 0.50 0.50 0.50 1
Diffuse TRUE Front 0.91 0.91 0.91 1 Back 0.91 0.91 0.91 1
Specular TRUE Front 0.72 0.72 0.72 1 Back 0.72 0.72 0.72 1
Emission TRUE Front 0 0 0 1 Back 0 0 0 1
Shininess TRUE Front 10 Back 10
}
Value OFF
osg::TexEnv {
UniqueID 8
}
Value OFF
When I run the example, I get errors like those:
Warning: Material::apply(State&) - not supported.
Warning: TexEnv::apply(State&) - not supported.
Looking at the code, this indicates that it’s an “error” caught by OSG, and
it doesn’t call the OpenGL API.
Now, I’m wondering, if the Value is OFF (and it also appears to be off when
I debug the code), why is the attribute applied anyway? What would I need
to do to have the attribute not applied?
Thanks!
I'm using OSG 3.6.3.
