Big seams of the texture when printing model on ProJet 660 Pro
AnsweredHello friends.
I make 3d scans of people by photogrammetry and RC and have some problem with a printing 3d model on 3D Systems ProJet 660 Pro printer.
There is my work process:
1. make 3d model by RC (without texture)
2. Export 3d model (.obj)
3. Cleanup 3d scan by ZBrush
4. Import model (.obj)
5. Generate texture by RC
6. Save result as obj + png texture
7. Send 3d model to printing
When 3d printer operator opens my 3d model, texture is low quality and with big seams:
But in RC and in ZBrush texture looks good, without seams:
Where is problem? Help me please.

I often have similar artifacts and I always use only one texture file, so that shouldn't be it.
It seems to me that it might be caused by difficult areas, I encounter it in deep recesses, where I cannot take ideal images. Could you upload a clay render so one can see if there are any alignment issues?

The problem is in the 3D printing sw :)
its internal algos downsample image resolution so use ONLY 4 ( 2K) k res and single texture.
wHAT tX RES ARE YOU USING NOW
in UNWRAP set the GUTTER to 3-4 so it creates bigger space between UV islands ( http://wiki.polycount.com/wiki/Edge_padding ) -
Hi,
not clear if you got visible seams on the printed part or on the printer software. Anyway I also got same visible seams on the printed part once I printed a PLY file (the Projet 660 does not accept OBJ), when RC was not even existing yet.
Convert the model to WRL and the issue should disappear.
