My solution is pretty expensive, and I have no idea if it would for 3D Canvas. Polytrans from Okino Software is a format converter that's very powerful it lets me import the Wavefront OBJ file without breaking it apart then export it into Truespace's native COB file format. When I'm done, I import the file back into Polytrans and export back to OBJ. This works for Truespace because Polytrans supports the Truespace native format. I don't think it supports 3D Canvas native format, if indeed, 3D Canvas has a native format. A far less expensive but more complicated work around that a lot of people use is John Wind's "Compose" utility. It works by remembering how a mesh was broken up, and then making sure it's reassembled properly. It's not the easiest program to use, however, and I still don't know if it will help you with 3D Canvas. Compose is a Java program that will work on both PC and Mac. You'll still be working in object format, but this should work. Here's the link to download Compose: http://home.tir.com/~johnwind/Compose11.zip -SMT

I'd rather stay in my lane than lay in my stain!
