Mudbox :: Working With Crease Edges On 2012 SAP 1

I'm working on a project right now where i need to use creased edges for sculpting.

I'm on Mudbox 2012 SAP 1, as mentioned in the title

Importing the FBX from Maya with smooth on (smooth preview) So The sculpying itself goes well.

But when it comes to transfert detail on creased topology, the problems start to emerge from the myst..................

So. I get ugly artefacts on the creased edges locations. I can bust'em out, but its very time consuming.

So Transfert to a non creased topology. Lovely transfert with no errors.

Then extracting vector displacement from the non-creased topology and the result is bad when rendering. The mesh looks smoothed without the sharp corners present on the sculpt.

So, trying to extract with non-creased topo as source and creased as target. Better, but still not good. Tryed use crease and hard edges, subdivided target topo.. Almost anything in fact.

Even flatten the non-creased topo before extracting maps. I'm loosing my teeth, weight, and my son doesn't remember my name.

Any workflows with creased edges ? Is the hole stuff better implemented in Mudbox 2013 ?
