Hi Sukender, I've merged your change and now I don't get the hangs and cow.3ds and lz.3ds are generated, but alas with the same artifacts that you are seeing. The trees look like an issue of how to handle billboards in 3ds, and the black textures? Don't know, an error in the material colour or model colour? Since the changes are another little step forward I've checked them in. It'd be cool to have the artifacts addressed though, as end users are almost certainly going to trip up when then try the 3ds export.
Cheers, Robert.
