Quixel Bridge fix for Houdini/Redshift (Update)

New update to make Quixel behave better with Houdini and RedShift was just released on Denes Dankhazi's Blogfolio. Gotta love anyone with “dank” in their name you know. Get the RedShift fix Here.

Basically, Quixles textures come in wrong, especially the displacement and this fixes that. Wrong might be the incorrect way as it’s fine in Unreal, just a RedShift implementation in Houdini is odd I guess?

“The Quixel Bridge fix for Houdini/Redshift.
For Houdini, I changed the 3D Asset, the 3D Plants and the Surfaces part.

How to use it:

  • Install the latest update (4.5) for Houdini in Quixel Bridge
    The plugin path is something like this: Megascans\Library\support\plugins\houdini\4.5\MSLiveLink\scripts\python\MSPlugin

  • Download the files and replace the original ones: download

    • ImportSurface.py goes to the AssetImporters folder

    • Import3D.py goes to the AssetImporters folder

    • ImportPlant.py goes to the AssetImporters folder

    • Redshift.py goes to the MaterialsSetup folder

  • The changes are significant

    • Subdiv settings

    • Shader settings

    • and most importantly Color Management settings for the RS Texture nodes
      Without this you can’t render correctly anything.
      Now the colors are using sRGB and everything else is linear as it should be.

  • You still have to fix the Displacement EXR textures thou.

    • Open in Photoshop (for example)

    • You’ll see there is data only in the red channel

    • Copy that as an the RGB layer and merge (Ctrl+E)

    • Sometimes you still have to linearize the data, use the exposure adjustment layer with gamma 0.454
