Three.js: Feature Request: Clear Coat tint and thickness

[raMaa026]

Hello,

The Clear coat shader is a great addition to three.js and big thanks whoever worked on it.
While exploring SketchFab settings, I have noticed that they have thickness and tint added as well, which ads more to the visual impact overall.

It would be a great help if these features could be implemented in three.js.

Thank you very much

Related: The proposed glTF clearcoat extension (draft) is here: KHR_materials_clearcoat. This is based on Autodesk Standard Surface and Dassault Systemes Enterprise PBR.

That proposal does not include the features suggested here (coat thickness and tint). But it does include a few things not yet in three.js: clearcoatMap and clearcoatRoughnessMap.

Would you be able to tell me if these two features are available for 1.0 version.

Thank you

I'm not sure what you mean by "1.0 version"... glTF, or three.js?

In either case – there are no plans to add clearcoat thickness or tint in either one right now. If you are using glTF and would like to see these supported, I would recommend commenting on https://github.com/KhronosGroup/glTF/pull/1677 and sharing examples and use cases if you can do so.

Thank you. I will try to do what you have suggested.

Closing for now. I'm adding #16977 here since it is the leading issue for enterprise PBR improvements. I recommend to proceed the discussion there.
