Finally, I had the time to modify the Quixel Bridge to Clarisse plug-in.
Tested with Clarisse 5.x, and 5.5 (Angie) as well.

How to use it:

• Close Bridge and Clarisse.
• Replace the original SetupPlugin.py file inside the \Megascans\Library\support\plugins\clarisse\1.4\MSLiveLink folder with this one: https://www.dropbox.com/s/u1jsmsz2y2lgk36/SetupPlugin.py?dl=0

Done.

What did I change? Well, a lot of things:

• There is no point to use the old standard shader or the Disney shader.
• I used the Autodesk Standard Surface, to get more and better control.
• I changed the attribute connections of course (different attribute names).
• Displacement offset is now set to -0.5 as always should be, for textures where the non-displacing value is 0.5 gray (you still have to fix the textures of course).
• Different Displace settings for Surfaces and 3d objects
  (because of the different scale offsets).
  • 3d Assets:
    • front_value: 10
    • bounds: 20
  • Surfaces:
    • front_value: 0.1
    • bounds: 0.2
• I set the single_channel_file_behavior to 1 (Force Luminance) for every texture_map (this will not change the behavior of the color maps but for compatibility reasons I’ll turned it on).
• Translucency connections and material settings for 3d Plants.
  • Thin Walled is turned on.
  • Double sided is turned on (for compatibility reasons).
  • The Translucency texture is now connected as SSS Color (with Thin Walled turned on that means Translucency).
• The Specular Color “nonsense” is now disabled.

I think that’s it.
