I exported an FBX from 3dsMax 2016 with 3 UV channels and vertex colors then imported that into MODO 901.
Exporting that same mesh back out of MODO 901 gives me 3 UV channels as expected but no vertex colors. A mesh with a single UV channel and single vertex color channel works fine.
This forum post seems to confirm multiple UVs + vertex color being broken in MODO:

I’ve filed a bug w/ The Foundry.
