Hi hybr! I can feel that I'm getting close.
I've done all what you say.. the project compile sucessfully, but I'm getting a black texture replacing my original static texture. I tried all first 8 texture units, as you say. I know that the imagestream is playing, because I can see the 'resize' messages in console. Did I forget something? (code attached below). Thanks, Almir ------------------ Read this topic online here: http://forum.openscenegraph.org/viewtopic.php?p=36755#36755
