Transpose Master Bug? Need Help!

[system]

Hi All,

I’m using Zbrush 4 with the latest Transpose Master …

There seems to be a bug where if I import an Obj that I exported from 3DS Max 2011, the transpose master just doesnt work!

I get either of these 2 problematic resulting errors:

a) As in the Jpg attached - it says the topology of the mesh has changed and hence asking if I want to delete or project on the new one…either choice will result in parts of the mesh exploding (verts snapping to incorrect positions)

or

b) It cant find the original mesh and gives me the errors of “polygon mismatch” and " mesh not found", so it grabs the basic PolyMesh3D star from the library to replace it.

Transpose Master works fine for all things Zbrush related - e.g. on the demo soldier. But once the import is from an OBJ in 3DS Max it doesnt like it. I’ve tried all the different options of exporting in 3DS Max but doesnt seem to have much difference. Also, I havent had any problems with OBJs from Max before and I can still use this method to update the model at any subdivision level (so technically on that front, the vert orders havent been changed by the obj export).

Can’t figure it out! Though I’ve noticed that by just turning on the SUBTOOL MASTER plugin and do nothing, turn it off. Only then, turn on the TRANSPOSE MASTER- I get a slightly different result - on the odd occasion/model, it works there after.

Anyone have similar problems with this - is there a known bug in Transpose Master with Z4?

Any help much appreciated…going crazy here!

Thanks

Phil

I’m not clear as to when you are importing an OBJ from Max. If you are importing the OBJ before using Transpose Master it shouldn’t make any difference. Please give a brief step by step of your working method just so I can be sure I understand you.

Hello Marcus

Thanks for the reply.

Here’s how I encountered the problem:

1. Used z spheres and sculpted my character.

2. Exported a mid level obj to max.

3. Imported in max as a single mesh and created a new retopolgised object from it

4. Exported this as an obj with zbrush presets in max 2011

5. Imported back into zbrush

6. Appended it to the original sculpt , subdivided it and project all

7. This worked fine

8. Added eyes/ and separate objects and that’s when I tried to test transpose master but it failed as described before.

So I was doing more tests now and in general it seems any mesh exported from max , doesn’t seem to work well with the transpose master plugin.

What I tried doing was import a cube from max, and append polymesh3ds to it (acting like character props)- run transpose master and it’s always the mesh from max that seems to cause problems…

Again it works fine on my original sculpt before I retopologised it … Just not with max exports…

Again any ideas from anyone welcome!

Thanks in advance

Actually, I tried exporting a simple object from Max to zbrush again.
But it seems to work fine now. (once I appended e.g. a ring polymesh to the subtool and used transpose master)

Tested on the retopologised mesh- still not working - must be corrupted somehow…

Transpose Master works by combining the subtools into a single mesh which is then split up again to transfer the pose. A new OBJ is created for each subtool. If the number of vertices in the OBJ that TM creates doesn’t match the number in the subtool then you’ll get the error message. If you want to send me the mesh I’ll take a look to see if I can find out what the problem is.

Hi marcus,

I replied in the other thread too actually … But I fixed the problem now.

It was basically some corruption or more like hidden verts or ngons that wasn’t clean in the mesh.

I’ve updated the mesh in max and welded verts (again) and removed anything that wasn’t a quad poly. Seems to work fine now.

The problem before must be some isolated verts possibly and when transpose master tried to re assemble the mesh after it was posed, it would get confused on where some of the verts should snap to. Hence the semi explosion after…

Thanks for The reply! Transpose master is indeed working as it should. But it was my user error importing from max that got it in a twist.

Interestingly enough maybe that’s why I had this problem which I also never encountered before possibly:
That is, when I smooth out the polys, go down a few subdivision levels and use the move brush, then go back up to the high poly subtool, a see theres a lot of pinching or snapping of verts / edges along the edges of the wireframe of the lowest poly subtool version! Found myself having to constantly resmooth the surface after I did a move! Maybe this was related to the weird corrupted mesh somehow…

Anyways thanks for the help again!

I’m glad you got it sorted.
No idea about the smoothing issue but very possibly due to the corrupted mesh.
