Layering turns my subtool completely black

ZBrush Usage Questions
#1

Just curious if anyone has figured out this issue at all. Currently I have a high poly mesh (traditional t-pose) I created and painted in ZBrush that has no UVs. I transposed the mesh (it’s 3 subtools btw) and got it to the desired pose, transferred the pose back to my high poly mesh, no problems yet.

I am now attempting to use UV Master to get my textures out of ZBrush. Unfortunately, I used layers on my high poly mesh before transposing, and UV Master does not seem to like this. Pressing “Bake All” on each subtool turns the subtools completely black.

I’ve attempted to resolve the issue with solutions given in this thread:

But none of those provide one with a solution to keep the texturing created earlier. Other searches I did on the subject didn’t really turn up anything related. Does anyone have any solutions or ideas to possibly resolve this issue, or should I begin my crying now?

I thank anyone and everyone in advance for any help/suggestions you might have.

Really quick, I just had an idea. I’m going to turn my subtools black/Bake All anyway, then unwrap those, export and import or just copy and transfer the UV’s to my polypainted meshes (save as a separate file). This “should” work. I guess I’ll find out, but I wanted to post this just in case. Thanks again.

I think I figured out what needed to be done. I kind of did what I thought needed to be done.

First, I took my t-posed high poly mesh and unwrapped each subtool (there were three in total for me) using UV Master . I then got my high poly texture from each subtool and exported/saved them.

After this I loaded my newly transposed mesh, the one that is in the new pose I created using Transpose Master. This had “Layers” associated with each subtool, so I “Baked All” for each subtool, removing these layers, but also turning all my subtools black. I then saved this new ZTL just in case as a separate tool.

My next step was to select my first subtool. I then switched over to my unwrapped t-pose mesh, selected the same subtool, and using UV Master I copied the UVs. Switching back to the transposed mesh, I pasted the UVs onto that same subtool, again using UV Master of course. The mesh is still black and when you do “New From Polypaint” the texture will also be black. Just click on the texture map and/or load your saved texture from before, and voila, it should fit on your mesh!

Repeat this for any other subtools that you have and everything “should” work out. Seems to have worked for me, so I’m happy about that.

Oh, one more thing. If you get an error when trying to apply your copied UVs to your mesh, just read the error and do what it says. Under the “UV Map” section, you’ll either have to increase the “UV Map Size” or decrease the “UV Map Border”. I did the latter by one and it seemed to work perfectly.

Just wanted to share this in case someone else runs across this issue. Seemed to have a lot of trouble figuring this out and trying to find information online about it, although in hindsight it seems to be fairly straightforward. Hope it helps someone.

Thanks.
