Hi, I use a Texture2DArray in my application.
All objects are rendered using shaders, and most of them use the TextureSampler2DArray data. So I made a top object in my scene graph, and I assign to its StateSet : - a uniform (SAMPLER2DArray) with the Texture2DArray unit number - the Texture2DArray This top object doesn't have any geometry, it's only to store a "common" stateset. And, thanks to stateset inheritance, all my objects shaders receive the uniform and the Texture2dArray binding. Everything works well if I bind the Texture2DArray to unit 0 or unit 1, but if I bind it to unit 2, 3, 4... the texture data are not binded (I saw that in gDebugger : texture unit is not binded) I need to bind it to unit 2 because some of my objects models use unit 0 and unit 1 for regular textures. Is there any reason for this problem ? How can I fix it ? My hardware : Quadro 4800 FX - Windows 7 My code : Code: p_root->getOrCreateStateSet()->setTextureAttribute(2, p_textureArray, osg::StateAttribute::ON|osg::StateAttribute::OVERRIDE); (I tried with "setTextureAttributeAndModes", it doesn't work, and according to this post : http://forum.openscenegraph.org/viewtopic.php?t=5237&highlight= I think I should use "setTextureAttribute") Thank you!
