Hey, i had opened this thread about importing obj file from max and my mesh exploding. But i tried to export my lowest level mesh to obj from zbrush, and right after it import the same obj file to the lowest level, without running it through any other app. And i got the same exploding mesh thing. also the mesh seem to be shrinked in size.
if anyone could help me with that, or point me to what the problem might be, i’d be very thankful.
Have no idea without looking at the obj in question. It sounds like the problem Zbrush used to have frequently back in 2.x with the geometry getting corrupted by a stray vertex somewhere, but that seldom happens anymore. Still, it does sound like your geometry has become corrupted somehow.
well here is the obj file i generated, i’m going to try it out some other meshes to see if this is a specif model problem or a problem in general.
hope it helps to get holds of my obj

The OBJ opens and subdivides for me in ZB 3.1 without issue.
Was your problem happening when trying to import the OBJ back into a live mesh tool?
yes, that was the problem. I have this mesh and the lowest level subdivision is that obj file. I was trying to work the pipeline max>zbrush but was getting exploding meshes. when i tried to check if my obj file exported from zbrush was the source of my problem and not the one coming from max.
And my live mesh as you called it, explodes when i import that OBJ file that came from zbrush and from that same mesh.
so basically what i did was
bring back subdivision level to 1
export my .obj file with mrg and not grp selected in the exporting options
import this same file to subdivision level 1 again
and my mesh explodes, help?
Well, I have no idea. Obviously it isnt normal. I suggest you follow the advice you were given in the other thread, as I have little experience with Max to ZB work.
It sounds like your tool has become corrupted for some reason or another, somewhere a long the line. This can sometimes happen for any number of reasons…problematic geometry, overlapping UVs, stray vertices…sometimes people push their system too far beyond the point where it can keep Zbrush stable, and errors occur (saving a tool after getting an “out of memory” error is usually a recipe for disaster.) I would think it might be a case of not importing the new mesh/UVs correctly, except you say it happens when importing a just exported base level mesh as well, which makes me think your tool is corrupted.
Here is the procedure for importing new UVs though, FWIW:

As explained in the other thread, you could subdive the base mesh with the new UVs up to the necessary level, and attempt to use mesh projection to capture the sculpted detail. You could also attempt to “repair” your current tool, by deleting all subdivision under the highest level, and using “Reconstruct subdivision” to try and rebuild the lower levels.
Like I said, Im only guessing, I’m sorry. I have no idea why your tool is acting like that. Out of curiosity, does it still “explode” if you disable UVs in the texture palette before reimporting?
Bingo_Jackson thanks a lot man. I’m now convinced it’s my mesh that is causing the problem. I just don’t know why. i was successful when i tried this other mesh i created.
It’s so frustrating when we stumble upon a problem and the problem comes from the least expected place, our own base mesh.
thanks again
