Main Issue:
See, I have this dark and strange looking tear-line on cc5 RTPT Kit 108

Are there any native OV tear-line materials that I can use in Omniverse Kit 108, that are optimized for RTPT?

This is just a slight difference between pt and rt2, that can be resolved with material workflow. This is not a bug.

Ok, so I try to make the material my self.

First attempt was to export the cc5 character with RT materials.

That ended up with no meshes exporter at all for tear-line and eye_occlusion :

So Nvidia Digital Humans are not available to me to test and learn the tear-line material for RTPT?

I tried importing Claire A2F demo characters tear-line material but that was not the solution either:

Next thing I tried to solve this was just use OV material library presets for glass.

no solution:

Please test with “White Mode” to identify it is is lighting, geometry, or materials. If the geometry still appears black, with white mode on, it is a geometry issue. Specifically probably a “normals” issue.

Hey, I kinda “solved” it!!

In the white mode it looks ok.

Turned out that the rendering setting tweaks that I made to make the hair and beard look good, caused the tear-line to look bad with RTPT.

Here is a video and description of it:

  1. show the character is CC5 so as native as possible. You can see how good & detailed the new eye system is.

  2. bring in another custom cc5 model I made last week and check the tear-line is not too dark or any ways wrong.

  3. closeup of the tear-line ( head mesh hided ) and you can barely see it, its wet and almost invisible!

  4. I build the cc5 studio light setup lights to look good in Kit 108 RTPT but I do not touch any other rendering settings ( just added tiny bloom ) so we are still on default settings

  5. Rendered 4K video of the female. No issues on tear-line - Yahooo!

  6. Imported the male, and you can see the same. No issues on tear-line

  7. 4k render of the male

So now my next challenge is to:

  1. tweak the hair material settings so it looks ok.

  2. tweak the rtpt rendering settings so hair looks good but it does not mess up the tear-line or eye-occlusion matrial

  3. contact Reallusion support / dev team to share all my results and find out if the best tool to make tear-line material to be just a bit more wetty and reflective already in character creator, not in Kit. Same goes to eye-occlusion
