As per a discussion over at the MODO forums, on the Glorious-ness of the new V4 release, Substance Designer was mentioned - I had never thought about being able to use my Substances within 3DC before.
Well I'm thinking about it now!
I think it would be a hella nice capability to have a Substance player rendering Substance texturess onto my 3D-Coat models!
I'ma add a suggestion over at the Allegorithmic suggestion site as well!

PS - It would be nice to get more use out of my Substances (and Substance Designer license) by having another 3D-app that supports it besides Unity! I hope this is taken under consideration!
