ZB to LW, UV Error

ZBrush Usage Questions
#1

I’ve imported a basemesh from LW, sculpted it and exported from ZB including disp and normal map. I’m going by Steve Warner’s guide from the Wiki but I am getting odd seam errors. The errors have appeared on more than one model so I’m thinking it’s something in my procedure.

ZBrush sculpt, level 5, GUV tiles, disp and normal map 2048

Tried switching between CC sub-d’s and standard sub-d’s. I didn’t originally have Smooth UVs activated in ZBrush. After the sculpt and it failing and turned them on. Not sure if that is the same as hitting SUV first. Have any of you encountered this before? I see a couple of search hits with similar results but none of them had any answers.

Thanks for any help.

I should also add that this problem doesn’t occur with just the displacement map, only when I add the normal map.

It came to mind that the newer versions of LW, 9.5 and up, added a smooth UV feature. I don’t know if this caused any problems but is there a way to disable smooth UVs in LW so I can test it?

Nothing? Crap. Is there any info I can add to help solve this problem?

I am not sure but it is worth a try. Check your verts and your UVs to make sure they are actually welded/merged together. There is options when exporting out of ZBrush to merge verts and I don’t think it is checked by default. It has caused seams in the past for me and that I pretty much the only thing I can think of off the top of my head. Hope it is somewhat helpful.
