Hi Oshyan!
To be clear. The plane started in mud from the default plane. I sent it to maya by way of obj. All I did in maya was to extrude a few times. Then I sent it back to MUD .fbx... I think it may have something to do with the UVs? THat is, in order to have X&Z (they are not visable to a Y planer map) I had to UV map... Cant understand why that would be an issue in TG though, if it was not an issue in MUD... So maybe not the maps.
Here is a test that worked ok. I found a image on line and loaded it as a stencil in mud. I did not prep the image to be used as a stencil but it still worked pretty good.
The vector preview:
[attach=1]
The sculpt:
[attach=2]
The render:
[attach=3]
Here you see that the details are coming through.
And after re-reading some of the info from the big thread, I began to play with "final multiplier". In every case so far, some adjustment to the FM setting is required.
What other setting may I alter from default, that could effect things the way FM does?
In the case of the HR Giger faces, I had to increase FM to 5. Otherwise the faces were too slight and hard to see. But at default 1, there was no spikes. IF I increase to say 50-200, the terrain explodes. The proper setting seems to be different for every vector, and also depending on the sculpter used. Can anyone tell me anything more about this?
Also from this test. It seems I cannot change the size in the image map shader. If I change it from the 500x500, it will lose all intended features.
This may be related to the way autodesk stuff works. For example, when working between mud and maya, you must use the same measurement system or problems pop up.
Can anyone one say why I loose my faces just from changing the size in the image map shader?
The thing is, if I can get the OP vector to work (or something basically like that) then I know I can do everything I wanted with this vector to TG stuff! So I really want it to work.

Thanks for helping!
And again (per another thread) You only need two nodes to work with vectors in TG if you save out an .exr as you Vector.
