Hacked!
I hope you have a lot of RAM in that Amiga! a 13 meg .3DS file? That's a lot
of triangles, it will hog memory, and as these things go, it won't tell you
you're out of memory until it's wasted an hour of your time. 🙁 Support for
Pixar formats? Renderman isn't so much as a file format as a language; it
resembles PostScript in that sense. Writing an importer would be very
difficult. There is an obscure subset of Renderman that's supposed to be used
for model exchange, but I haven't ever heard of anyone who uses it.
