Ok, here is the code... It's a modified version of osgartsimple.cpp: (see attachment) The OSG file - karsten.osg - (generated with 3ds Max) has 3 main textures. I want to change one of them with a imagesequence or movie file (quicktime .mov) (I have both of them). I haven't a Geode object, only a VideoGeode... how can I create a stateset to change the texture? Thanks! ------------------ Read this topic online here: http://forum.openscenegraph.org/viewtopic.php?p=36711#36711
