I am new to ZBrush 3.5 and ZBrushCentral. I think ZBrush is awesome and I am experiencing great sculpting results. I create my base mesh in Maya. While painting on my model recently, I am experiencing a problem with painting on one side of a thin part of the model. When I do this, it is painting through to the backside. I am strictly using RGB polypainting. I am not sure what is causing this problem.
Thanks in advance for any help, much appreciated.
Go to brush menu >auto masking> turn on backfacemask… that should fix it.
Thanks for your advise regarding the use of backface masking. I am however,
still experiencing some bleed through after following the steps you proposed.
It is not solid in appearance as before, but seems spotty, almost in a gidlike pattern. The colors also seem to seperate into reddish and yellow patterns. Do I need to tweak some settings or something? Thanks again
This appears to be a Known issue in 3.5 :
BFM works for sculpting, but not very well for painting and masking. It is being looked in to. In the mean time, I would advise taking your object down to base level where it is easier to isolate individual polygons, turn polyframe on, and completely isolate the front and back polygons, and group them into a single polygroup by hitting “group visible” in the polygroup menu. That way you can quickly and easily hide one side or the other at higher resolutions, and paint on the other.
OR
Export your high Sub-D level as an OBJ, import it into ZB 3.1 where BFM works well, do your polypaint there, export the painted mesh as a ZTL, load that into 3.5 and use the “Reconstruct SubDivision” in the Geometry palette to rebuild the lower levels.
Thanks for your fix; the second option worked out quite well. Its a shame that the new version of zbrush has these bugs, its going to be a lot more work importing and exporting between the two versions.
