Definitions of PBR fabric properties for importing textures

I'm importing scanned PBR fabric textures into CLO3D, and I'm looking for more detailed information about the fabric properties in CLO3D so that I can set them to values that give a consistent appearance for the same PBR texture in CLO3D compared with other 3D tools.

This is my recipe so far:

1. Set the fabric Type to Fabric_Matte

2. Import the texture images (my textures have base colour, normals, displacement, roughness and metallic)

3. Make sure the Roughness is set to Map (not Intensity)

4. Render a high quality image

My questions are:

1. The Roughness and Metallic maps have Intensity sliders that go from 0 to 100. The default for Fabric_Matte is Roughness 50 and Metalness 0. What do these values correspond to in other 3D tools (which usually scale up and down from 1.0)? What value should I set the Metalness Intensity to in order to get a standard PBR appearance?

2. The Reflection Intensity also goes from 0 to 100. The default for Fabric_Matte is 15. What do these values correspond to in other 3D tools? Is this related to the F0 or Index of Refraction settings in other tools?

Ideally, I would like a single recipe for the CLO3D fabric properties that gives a consistent appearance in CLO3D for a wide variety of PBR textures.

Thanks for reading, any advice would be appreciated!

  There are different Fabric >>shader<< types within CLO3D. The CLO3D render engine is vray and hence the fabric shader >types< need to be allocated to the PBR material maps. This means you set your 'fabric' material shader >type< from the drop down menu (eg: matte, metallic, glass,  etc) which then brings up a new vray shader modal (list) which may or may not have certain map settings available based on the material >type< of shader you select. Once you have set your shader type you can navigate through and load the types of image maps (PBR) into the relevant slots.

  You will find these follow the basic vray materials which are also listed on the CLO3D manual help pages.

  Hi yellowtail, 

   

  Thanks for your questions. 

  In CLO, there are two types of roughness property.
  One is for "Intensity", and the other is "Map".In the "Intensity" type, the CLO sliders 0~100  correspond to 0.0~1.0 in other 3D tools. In the "Map" type, it works differently. The CLO 0~50 corresponds to 0.0~1.0 in other 3D tools.
  
  

  In CLO users can control reflection intensity by property editor. It corresponds to 0.0~1.0 in other 3D tools.

  And the reflection intensity defaults to 15 because we optimized for the cloth render environment.

   

  Thanks, 

  CLO Team

  Thanks ottoline and to the CLO Team. The reminder about the connection with VRAY and the advice about the sliders was very helpful. I've now created a recipe that gives faithful appearance of our scanned textures in CLO3D.

  Cheers!
