Re: [osg-users] Texture2DArray and invalid enumerant error
Hi Chris, OSG svn/trunk + OSG-3.3.x dev series has a modification to Texture2DArray that makes sure that no modes get applied when you use setTextureAttributeAndModes() for a Texture2DArray. Robert.

Re: [osg-users] Texture2DArray and invalid enumerant error
Hi Glenn, Since TextureArrays are supposed to work only with programmable pipeline, there is no such GL Mode as GL_TEXTURE_2D_ARRAY. It could be considered a bug in OSG that setting this mode is attempted. Workaround: don't attach the textureArray with setTextureAttributeAndModes but with setTextureAttribute.
