Displacement and multiple maps

Greetings Eat 3D frequenters,
I have a couple of questions. The first being: Is there a way to export displacement maps from xnormal?
the second might be a little tougher to answer. Say I have two separate meshes that I detailed in Zbrush yet they are part of the same mesh (I couldn't import the whole thing into Zbrush for subdivision reasons). Now I want to create a displacement map or normal map from both meshes but I need them on the same UV space. I could take them both into photoshop, but then I have to lay the one on top of the other and then do a multiply or screen or something but that changes the shade of grey in the negative space with displacement maps and causes problems, so is there anyway to generate a displacement or normal map from two different meshes but onto one map with xnormal?
Thanks for any info on this.

Height/distance and vector displacement maps, yep.
Notice however that to generate a "typical" displacement map you should pass the lowpoly mesh already subdivided a few times to xNormal.
xNormal does not subdivide the mesh, you must do it manually.
>is there anyway to generate a displacement or normal map from two different meshes but onto one map with xnormal?
Yes. xNormal allows you to specify meshes in different files to generate a merged unique map. To make that, the UV's should not overlap.
If the lowpoly mesh is the base mesh you used to subdivide/sculpt the highpoly mesh then you could use the "Match UV" mode(aka dual parameterization), because the highpoly mesh's UV will be contained/limited into the lowpoly mesh's ones... In that way you can skip to setup the cages.
