Please,
One problem of interoperatibility and pipeline from mudbox to 3ds max is the complete absence of Ptex support.
Now we know that mudbox comeback to us with many features and with a new life...
So, I think that is necessary to have a support for this OPEN support .... PTEX is necessary with sculpt becouse we have opportunity to work without UV and with a for zoom quality level details.
I know that is a old request but is time to do!
Mudbox is a real killer tool for us!
(PS: maya have Ptex support... ****!)
