Although it’s technically possible to remap the IOR value to a 0 - 1 range so it could be baked to a texture, it would require a custom shader in whatever software you import the baked texture into, making it pretty inefficient when comparing to just setting the variable in whatever shader you are using. From my understanding you shouldn’t need to touch the IOR for the majority of materials, with only glass, water, and ice being some exceptions.

So what about if you are making an atlas texture? You would need an IOR map, right? Pls just add it here:

It’s just for those who need it. It doesn’t have to be a feature that everyone uses. I usually just multiply the texture with a Math node to keep it in 0-1 range: Using IOR vaules in a texture map? - #4 by DNorman

Lastly the subsurface radius value could be exported, but I’m not 100% sure what it’s really doing yet and I need to do some more research into that to fully understand if it’s something you would want to export.

Subsurface radius value is basically Subsurface color in 4.0. You can plug in an rgb node and it works fine.

One of the things I loved about the Principled Baker addon:

Principled Baker - Bake PBR textures with a few clicks

Principled Baker for Blender 2.79 here: https://github.com/danielenger/Principled-Baker_for_2-79 Bake PBR textures with a few clicks Features: Autodetection of what needs to be baked by connected inputs Manual selection for texture channels bake almost all Principled BSDF (and more) inputs (Color, Metallic, Roughness, etc.) to image textures Autodetection/Manual selection also for Alpha, Emission, Ambient Occlusion (from node; 2.80 only), Diffuse, Glossiness (invert Roughness), Bump (as hi…

is that all the slots of the Principled Shader can be baked out into a texture. Didn’t matter which one was used more. Its better to have more options than less because somebody may need to use those slots even though its not widely used.

It gives people the freedom to bake whatever they want to a texture from the principled shader. How you use the resulting baked out texture is up to you.
