Transpose Master deleting subdivision levels

ZBrush Usage Questions
#1

I’m having a few troubles with Transpose Master.
After transposing I find some subtools have lost their subdivision, they have only subdivision level one, now called one but that used to be the highest (5 in my case) and if I try to reconstruct subdiv nothing happens.

I had also other issues with it. It very easily explodes polygons on five edge stars and it cannot load the saved TPoses. It started asking for obj files instead of the saved ZTL and even if loaded with the obj files it asks (converted TPoses originally saved as ZTL) it crashes.

Could it be that’s my machine playing tricks? Should I reinstall Zbrush? Or just Transpose Master? Any clue?

it’s asking for certain files because it failed once and then you tried again. It writes to temp files and then is looking for them again…but can’t find them because it had to overwrite them…or something. I don’t know the ins and outs of it, but that’s what i gathered from it doing that to me.

To fix the problem I always reboot. I know…not a fix, but at least a work around. Still only works some of the time though…so in other words…I’ve got nothing, other than having the same problem.

Thanks, so here’s no reason to reinstall anything then. Is it a compatibility problem you think? I’m on Vista 64, I recently moved from XP64 because I used to have another set of bugs that I became tired of.

I devised a workaround to get those lost subdiv levels back. You first have to save the TPose, then once the posing is done and you have the model at the highest level without lower subdivs you load the TPose as a tool, then you do a group split and you’ll end up with the model divided into the original subtools. This because Transpose Master assigns one polygroup to each subtool. Then you load a ZSphere and rigging>select mesh the low subdivision version of the subtool from the split TPose. Click Edit Topology, and then you make the tool very small on your screen, and with a very large brush and holding down the shift key you sweep across it thus reviving the geometry.
At this point you deselect Edit Topology, click “delete mesh” in the rigging palette and load instead the high res that came out of the transpose Master, select Edit Topolgy again, click on Projection and Bob’s your Uncle.
You may still have to fiddle with the projection parameters but you’ll get 99.9% of the details back.
Then make an adaptive skin, append it as a subtool to the transposed mesh and delete the old one that doesn’t have subdiv levels.

Transpose Master relies on the import of OBJs for its functionality. Unfortunately sometimes particular OBJs can cause the normals to flip on import into ZBrush which results in the loss of the lower subdivision levels. It’s best to avoid poses that fold polygons closely on top of each other so that they intersect, or subtools that contain some parts that have been mirrored.
