ZBrush 3.2 Mac - export collapses points to (0, 0, 0)

ZBrush Usage Questions

I"m having an issue in ZBrush 3.2 with one of my tools. The problem is that any time I try to export it, at any subdivision level, it collapses all of the points to the (0, 0, 0) position. It also does this with GoZ. I have made sure that my export scale was set to 1, after noticing that it was set to NaN, but this made no difference.

This issue also seems to be occurring when I decimate the mesh. When I preprocess it, it shows the titles of the loading steps, but never actually runs through a loading bar before it finishes. When I actually go to decimate it, the mesh disappears - presumably because it has collapsed all the points here as well.

If I try to import the collapsed mesh into another program (maya, c4d, etc), it shows that all the points and polygons are still present, but that they are all at 0.

I have uploaded the tool to my website, so that you guys can take a look at it. Remember that it will only open in ZBrush 3.2 though.

Thanks a bunch!

has anybody tried this or experienced the same issue with my tool?

Hi, works just fine for me: remember to check, in the export panel, that you have “nan” anywhere (as I opened the tool I got nan in the scale and the XYZ offsets).

#4

a-ha! That did it for me. I forgot to check the offset values. Although I don’t entirely understand why they would shrink the scale, as long as the scale is set to 1.

Also, is there anything that would set these values to NaN? We just got a new kitten at home who loves to walk across keyboards… :rolleyes:

I also have a cat (BTW, he’s about 20 pounds, so it’s not a kitten :lol:), but that’s not the reason :lol:

I really don’t know what triggers those nan values: I found out that it especially occurs when exporting from Lightwave…

I have been having this same problem. Changing the export settings to 1 seems to fix my .OBJ export problem. However when I try to use GOz I get this error in my script editor in maya. I dont know how to fix this.
