3D Max Exporter and PDR workflow?

Having some trouble with the workflow…

I currently have models created in Max and textured in Substance Painter. Maps applied to models back in Max but I can’t seem to find the right way to export from Max into Sketchfab to end up with all the textures applied.

I have base colour, roughness, metallic and normal maps. Which would be easy enough to just export the model into Sketchfab and then manually apply the maps there but I have 57 models!

Using the Standard Material in Max won’t work because it doesn’t have material slots for roughness, metallic or normal maps.
I can apply those maps to a Physical or VRay material, but when I export using the Sketchfab for Max exporter I only get the base material applied to the models in Sketchfab.

Exporting as FBX or OBJ I get the same sort of issue, they don’t recognise the material types on export and don’t bring across the maps. And I don’t want or need to bake them because I’ve already done the work in Substance.

Wouldn’t it be great if there was a Universal PDR shader that worked across the board with applications? :slight_smile: Wishful thinking…

Does anyone have any ideas on how I can make this work without manually having to apply the textures in Sketchfab? I have a lot more model bundles like this I want to upload and I’m not looking forward to the manual process of it all.


There is a list of suffixes you can use when naming your textures, seek for “automatic pbr mapping”.
Hope this is what you look for


Awesome, thank you very much. Looks like that will work for what I’m doing.
