I am working with Cinema and it is horrible how MED can't import their exported files correctly. So I export the whole scene by materials via FBX because unfortunately MED somehow only finds and loads only one texture. So, after merging, I have a mesh with several groups. These groups are not due to the different material meshes, those meshes consists of groups, too. So basically, I will merge my scene eventually by 5-12 imports and the whole scene consists of a total of 64-128 groups.

I could go without that group tool if I had a tool that would import my Cinema 4D scene correctly once. That would save time even more!
