Hi there (first sorry for the bad english).

I’m new on the forum and quite new in 3D.
I work on C4D and begin testing Mudbox.
I’m sculpting a female human body. Model a low def base mesh in C4D, unwrap UVs, export .obj then import Mudbox.
Mudbox is great, i like to work with BUT ... why i create a displacement map something goes wrong. There are lots of artifacts on the seams on where my mesh “stops” (in the eyes and mouth).

Some possibilities :
- Compatibility problems between C4D and mudbox. but a lot of users seems to find no problems with the C4D / mudbow workflow.
- my UV map is wrong (i dont see any problems but as i’m not very used to UVs maybe i’ve made some mistakes ...)
- Wrong Disp Map creation settings. But i check the mudbox help and everything looks ok.

i’ll not cry but i’m not far… if anybody has an idea of what goes wrong or what mistakes i have made, i’ll be very thankful.
thx u !

Pierre

looks like your search distance is to high… try 1 or 2…
sometimes you have to combine two maps to get a decent one…

and you should try to use subD as baking method…

a rule for meshes is dont crate holes if you like to bake a displacement map…
for the mouth and the eyes its best to model a eye socket and a closed mouth cavity…
border edges are allways problem areas…

ok i have to make some more tests but selecting “closest to the model” in choose sample combobox seems to solve the problem.
will report the problems if some new appears !
thx

I had this kind of problem too because I cut my uvs on “non perfect” loop”. You must avoid cutting your uvs where you have 5 edges meeting. you must have only vertices with 4 edges meeting everywhere along the lin of your uv seem.

I think this is a very valid tip, I saw your previous post on this and meant to comment then, Thanks.
