Usually I would use MisfitModel3d to model, but I've recently moved to OSX, and I can't get it to compile. I have blender but it doesn't have a mm3d or ms3d exporter (Well, it has a ms3d exporter, but it is still in development, and doesn't yet support all the features I need). So, are there any alternatives to Misfit Model 3D on OSX?
Actually you don't need to compile the program. You should be able to download the binaries from here: http://naranja.umh.es/~atg/software-qt3.html
