Unified Skin Errors 3.5r3

ZBrush Usage Questions
#1

I’ve been getting strange errors in 3.5r3 which were not in 3.5r2 using unified skinning, there seems to be a calculation problem or “empty spot” in the negative -x-y(possibly -z). If you look at the preview window and compare where the errors are occurring the happen in the lower left of the pivot point, i’ve had this happen with different mesh’s all made with zbrush. I’ve even been able to replicate using the primitives converted to pm3d and tilted so they are crossing through the pivot point near that space.
The unified skin is creating a cube with a hole in the middle in that spot.

ALSO there seems to be another problem with unified skin not skinning past the bounds of the preview window. this has happened off of a simple zsphere chain. (example2)

yeah, Having the same problem here

#3

glad i’m not the only one. i think i’ll have to try to avoid that area if possible. although no idea whats going on with that zsphere.

#4

hey space thats odd almost looks like a subtraction from the clipping plane with the new remesh feature another new bug or anomaly that we have to avoid now… lol…:wink:

#5

troy i used the normal unified skin palette, don’t know if that makes a difference though, has this happened to you at all?

#6

no i have not had this problem yet maybe its a translation coding problem from zbrush 3.5 r2 to the coding of zbrush 3.5 r3… what version of zbrush was this tool from i have found that many times i have to do a combination of mesh resolution and subd level steps to get the result i was going for… have you tried exporting out the original mesh and then importing it in as an object and then saving it as ztool… had a problem once when i switched a subtool and it would crash my zbrush instantly… but when i saved out each subtool as an object and then saved them out separately an then i imported each one by one… it seemed to fix what ever was making my mesh crash zsketch was crashing alot on me in zbrush3.5 r2 but now it seems to be fine… maybe the same thing will work in your case but so far i have been fairly happy with the new unified algorithm and new project all calculation… but i will let you know if anything like this comes up my way…

let me know if this works for you…:wink:

#7

Well I found the error by just trying to make a skin cube for sculpting… I plan to just move the tool to r2 for any work that I need to project a skin till we find a work around. Atleast this is better then the 3.5 to 3.1 I was doing last week for plugins :slight_smile:

#8

Yeah simply try to unify skin the simple Zbrush Cube.
take a look:

The R2 Release does not seam to have these issues.

In R3…

While in ZSpheres mode, Press A to generate an adaptive preview. Then press “Subtool:ReMesh all” to have a new Unified skin added as a subtool.

Note 1: In R3, you can use the “Subtool:ReMesh all” to generate unified skin for any combination of ZSpheres, PolyMesh3D and parametric subtools objects.

Note 2: In R3, after generating a unified skin from ZSphers, you can select the new subtool and click “Project All” to project the ZSpheres volume to the new unified skin.

marcus just tested using the remesh button instead of unified skin palette, same error that i listed in first post with the square/hole in the lower left of pivot

#11

it doesn’t solve the problem marcus, same with the cube example.

#12

Any work arounds yet?? Im almost ready to deactivate r3 and reinstall r2!

#13

im assuming this is what they were talking about is the transitional phase to zbrush 4 when it comes out all though this is more a bug than anything… i cant see what use turning your zsphere rig into a cube would have even if resolution is cranked way up either way its the same out come… so is there any word on if this is a bug and if this is going to be fixed by zbrush 4 release?
as was already pointed out by nickz here http://www.zbrushcentral.com/showthread.php?t=78579 we cant even do unified skin of a plain zsphere rig anymore but yet we can can project all sketch spheres volume but we cant project a volume of an actual rig… any word on this at all from one of the mods?:confused:

#14

i’ve uploaded a simple adaptive skin made from zspheres, and the unified mesh that was made at a resolution of 512, higher resolutions cause the same problems. as you can see there are pieces of geometry that should not be there and distortion in the main geometry as well.

Having the same EXACT issue here when using unified skin on a cube3d. :cry:

#16

@ArtByBpc and everyone who likes to convert a cube3d-primitve with unified skin:

IF (only if you’re REALLY into this kind of 8x8x8-cube-thingy) then use a unified skin modifier with a resolution of 16 AND after that use a resolution of 8 with the remesh all option on all axis’ on the new 16x16x16 cube. you’ll get one of these delicious 8x8x8 polycubes! yeah!

enjoy the sunshine!!

chem!

ps: of course, this doesn’t solve the original problem posted by spaceboy412, and without downloading his testmesh, you’ll really get some wacky results trying to use unified skin on the zbrush dog mesh. (you gotta look closely, though…)

#17

That’s not what it’s about. Of course it’s not hard to get an 8x8x8 box into ZBrush somehow.

The point is there is a bug with the unified skin in R3.

#18

roger that! i am sorry.

chem!

#19

same here

I was having the same problem and after a bit of tweaking found that this problem only seems to occur when you set the resolution to 8.

Changing this to 16 seemes to work for me, not sure if you guys get the same?
