I imported some Daz sets into Iclone with 3dxchange. (used the "Write UV Coordinates", Write Normals and Collect Maps in the export). They look fine in 3dxchange, and look fine in Iclone with Medium render. If I do a preview render of the video, they look fine. But if I do a final high quality render, the materials look distressed and broken up. Is this a common problem? Is there any fix? Am I exporting correctly?

Can you post example images? There is a lot of people here who would be able to help if they can see the problem.

Here's a sample. The first is a "preview render" and the second is a "final render". You can see how the materials appear torn and distressed.

If anyone else is struggling with this, I have found that selecting the corrupted materials in Iclone and bringing up the "self-illumination" slider will restore the missing and broken textures.

that isn't a good option unless you want no shadows.
you asked if your exporting wrong, yet provided no info.

I mention it as the only positive result I have had so far, thinking it might also be a clue as to what is happening. In my first post I mentioned that my export settings included "Write UV Coordinates", "Write Normals" and "Collect Maps". These settings in the advanced tab were the ones I found in an online tutorial about how to export these Daz sets to Iclone.   They do look fine with these settings in 3dxchange and in the Iclone "preview" render mode. But clearly not in the "final rendering" mode. 

I have also tried it with "write object statements" and "original maps" and "ignore invisible nodes" checked. But no luck with any magic combination by trial-and-error. 

Reviewing my original tutorial, I see one possible issue. It says that in 3dxchange, I should check a box in the Scene Tree called "2 Sided" to cap any back faced areas. My version of 3dxchange doesn't seem to have and check box for 2 Sided. 

The issue does seem related to shadows, I think, since the "self-illumination" slider restores the missiing textures.

i was referring to the export format......
Daz fbx expports have been known to cause texture issues on props.
in most cases its the bump or normal maps.
try a obj export........
and use fbx for avatars

.

Yes bump imports way too strong
In DS 4.9 it is better than previous versions

Thanks for the suggestion. Unfortunately, there were exported as obj file, not fbx. That's what the tutorial called for as well.
