Oh yeah. Just wanted to let developers know that I’m modifying the SimpleMesh structure for the SDK over the next couple of days to support grouping. I guess I didn’t think I needed it but some 3D formats support it and it would be a waste not to support it. So the mesh structure stays the same, it’ll just be embedded in n number of groups when you read the file. If the format you’re writing an importer for doesn’t support grouping (or there are not groups present in the file) just create a default one and add the 3D info to that. I’ll be posting a tutorial and the complete code for loading a couple of formats in the next few days to show you how to do this if you’re still unclear. Thanks.
