Activated octree culling logic as a default Wide spread bug fixes related to occlusion culling and GPU resource management Implemented logic to automatically enable alpha blending for materials that do not contain an alpha blending statement but have a material-level opacity value set less than 1.0 Extended the krobject file format to 256 characters for material names. Added logic to prevent exported krobject files from being corrupted when long material names are used. --HG-- extra : convert_revision : svn%3A7752d6cf-9f14-4ad2-affc-04f1e67b81a5/trunk%4096
