I have imported a large obj file into 3ds max that I exported from a visual molecular program. It has a group of proteins that are one mesh. I was able to Explode the proteins into separate objects successfully once (in a new cartoon representation), but when I exported the obj file again with a different representation (quick surf), 3ds max stops responding every time I try to use the Explode function. It's surprising because this new representation has far fewer verts: 1 million+ compared to 800k. Any help is appreciated!
