Quick help with UV export.

ZBrush Usage Questions
#1

Hello,

So I am doing some models for 3d printing but it has to be color and they need it in WRL.

  1. I did the modeling
  2. I dynameshed and made shells.

  1. Retopo through zremesh.

  2. UV Master/unwrap/paste uv’s

  3. Generate textures from polypaint.

  4. Export VRLM

  5. Opened in meshlab and texture loads wrong as if it were mapped wrong?

Can anyone point me towards the right direction I have been trying quite a few things on my own but it would really help me if someone could help me with it. Seems to be the same issue even if I texture a simple cube. At the same time OBJ’s appear normal but those pull their color/texture info from vertices?

  1. How it looks in zbrush prior to exporting

  2. How it loads into meshlab

Would really need some help with this :slight_smile:

Ok so I discovered that flip horizontal and rotate 180. in photoshop helps in some cases so its a texture/uv orientation issue but how to get consistent results I still have no idea. Within zbrush I can go into UV settings and flip UV “V” and it loads correctly if I bring something from outside into zbrush but when I export it the same problem appears. Does anyone have any clue as of why this could happen?

Update:

So I can now manage to export my WRL-s from zbrush with varying levels of success.
I export my subtools as wrl-s with textures and after I flip the textures they seem to ok to me but when I send them out others still claim there is trouble with the UV’s somehow. I checked by uploading my files to shapeways and the shapeways preview shows them to be correct and the textures load allright but still cannot understand why would 3ds’max or blender give me grief.

Peace out,

  1. UV Master/unwrap/paste uv’s

Why did you paste UVs?

Go back to UV Master, and hit unwrap… this should get your UVs straightened out.
Then recreate your texture from polypaint.

You should not have to do any texture/UV flipping when you’re in ZBrush.

(You might have to flip V on export, depending on the destination)

I only get the Vertical flip issue when I export WRL-s the problem is not there with OBJ’s. I pasted UV’s because I worked on a clone, when unwrapping but thats optional as I know now. Thanks for the reply :slight_smile:
