Hi, I build OSG for iOS with OpenGLES 3.0 support only. Now I got some problems:
Warning: Material::apply(State&) - not supported.
Warning: detected OpenGL error 'invalid operation' at after RenderBin::draw(..).

In CMake I saw possibility for build with support OpenGLES 2.0 and 3.0 together.

Questions:
1. Does OSG got full support with OpenGLES 3.0?
2. Is build OSG with OpenGLES 3.0 enough for success? Or 2.0 or both versions better?

Thank you!

Cheers,
Vlad

What you're seeing is normal. OpenGL ES 3.0 does not support the old fixed-function Material feature. OSG is warning you that you are trying to render a piece of geometry that uses this feature.

Your solution is to modify your scene to not use Material states and instead write shaders to create the desired appearance.
