Hi

Found the problem but don't know why.

I have the following code to turn on/off glColorMaterial() to preserve assigned colours to mesh triangles.

        // material colour tracking
        if (mMaterialColourTrackCurrentColour)
        {
            // needed so material for triangles will be set from colour map
            glv.glColorMaterial( GL.GL_FRONT_AND_BACK, GL2.GL_AMBIENT_AND_DIFFUSE ); // call glColorMaterial before enabling GL_COLOR_MATERIAL
            glv.glEnable( GL2.GL_COLOR_MATERIAL );
        }

It would appear that this is conflicting when I call glDrawElements() but is fine when I use glDrawArrays()??
