I've been meshing for IMVU using 3ds Max 7. The site is very specific and can only accept .xmf files for the meshes, .xrf for the materials and .xsf for skeletons.
I find that if I export an object out of one scene and into another I can no longer export anything out of the scene that received the import. Or at least not as a .xmf file. The .xmf file turns up empty if opened notepad.
Even though I only export the lower portion of a skirt, it still imports all the items from the old scene and I deleted everything but the skirt that I needed. Still, even the things in the scene that previously exported just fine won't work at this point.
Usually I would start over again, but I put a lot of time into the item I had modeled and I'm hoping maybe someone will be able to give me a little advice on this?
Sorry if I'm not providing enough information... I can't think of what's pertinent at the moment besides what I have provided.
