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.

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.
