Hi all, I think I had a similar problem some weeks ago (with OpenSG1.8). The implementation of MaterialChunk::changeFrom() and MaterialChunk::activate() had some inconsistencies. Carsten Neumann commited a patch to 1.8 and 2.0 (I think on 31.01.2012). So if you use a version that is older that may be the problem.
