[osg-users] [build] Build OSG on iOS with support OpenGLES 3.0

[Chris Hanson]

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.
