Displacement Map from wrong angle

[system]

Hello,
For a terrain mesh that came from World Machine, I’m trying to make a displacement map in ZBrush (after sculpting) but what I get is a displacement map of the terrain from the side (as it look once imported), not from the top view as a 3D package would apply it.

I created the UVs in ZBrush just by pressing create under UV map and sleecting uvp (planar). The Terrain mesh came from WorldMachine without UVs.

Being new to this, I’m doing something wrong, I just don;t what it is. Please point me in the right direction.
Thank you

Uvp is a Z+ projection if I recall correctly. Just rotate your mesh with the deformer so the direction you want is facing Z+.

Also. If you’re using displacement to drive all of your deformation from a flat terrain mesh you’ll want to capture your alpha using grabdoc.

Thank you, but can you show me how to do the Z+ stuff, I don’t even know what Z+ is, and how to do it. I’m a heavy Vue and World Machine user than hopes to add ZBrush goodness to terrains. Where do I find that Z+ thing.

About the grabdoc, do I need it if I bring from world machine a terrain that has all the major features, and only added (a lot) of details with the Geometry HD sculpting?

Thanks a lot

Sorry, I see, you mean the Z axis (positive).
When you say use the deformer, you do not mean the rotate tool, maybe you mean somewhere under Tool->Deformation, when I go there I find many parameters and cannot see a deformer tool for changing.

It’s just that ZBrush has the absolute weirdest user interface mankind could ever come up with, but it does brilliant things so I’m learning it.

Does Zbrush consider Z up? each 3D package calls the up axis differently(some Y some Z).
Thank you

Z is depth. Y is vertical.

Tool>deformation>rotate

Turn on your Floor (shift+P) - center of the grid you’ll get an axis gizmo. Z is blue as per all programs.
