Hello Herwin-du,

I had the same issue some time ago, here are some tips you should try as they helped me solve the issue.

However, if they don’t work, post again and this time describe step by step what you’re doing.

  1. Set the export option to Default. This means Vertex Scale 1.0 and # of Digits to 6.

  2. Make sure both and UV Map and Mesh are Welded. Sometimes, a model isn’t welded in the UV Map and this leads to explosions.

  3. When Subdividing the model, make sure that the UV is being kept on the original UV as opposed to being divided alongside the model.

  4. If all fails, do this:
    -Go to the lowest level of the model (Level 1).
    -Export the Model in OBJ format and make sure Quad and Mrg Option are both enabled.
    -Import the model back in 3DS Max, make sure that Unify and Single import option are checked.
    -Now correct the UV’s and export the model into OBJ format.
    -Import the model back in 3DS Max again (yes, Max again).
    -Check UV’s again or you can just export it again into OBJ format.
    -Optional step, import the model in 3DS Max again (for some people it’s important, for some, not so much).
    -Again, export it on OBJ format.
    -Now, import the model in Zbrush, make sure it matches the Lowest level SUB-D.
    -Now, look and see if the model still is having UV problems or not.

The last step should solve the issue. For some reason, people like me must import and export the model several times before Zbrush gets the correct UV’s in.

If it’s doesn’t work, post what you’re doing so we can help better.

Sorry to dredge up an older link but I am having a similar problem with eyeballs I made in max and importing them into zbrush into an existing bust I made. When I import and eyeballs they are scaled up about 3x the size they were when I fitted them into the bust in max.

To fit the eyeballs in I exported out my level 4 from ZB of the bust, imported the obj bust into max, made the eyeballs and fit them, deleted the obj bust, attached the eyeballs as one object and exported as obj. I even tried aligning the pivot point to 0,0, and running xforms.

It just always seems to rest the eyeballs back into the busts head at 0,0 and it scales them up 3x.

Any ideas would be great. Maybe I am exporting out the initial bust incorrectly? I did try the above suggestion of setting my max obj export options to default, still the same result.

I can post pics if needed.

Thanks for any help!

I know what you mean. Up-to-date I tried Max 7,8,9 and 2008 and they all have the same issue.

Sometimes I get lucky and use the Reset XRef several times on a model and need to export it once only.

I don’t know how or why, but Maya has the same issue. I have yet to experience it with XSI for some reason.
