I'm trying to rip the Kingdom Key model from Kingdom Hearts III (PS4), and while I got the diffuse and normal maps properly extracted, there's also this weird map:



Is it supposed to be some sort of a special PBR map? It doesn't seem to have an AO channel, so I don't really know.

If anyone can figure out what it is, thank you in advance.

the maps is for rendering certain shaders, sometimes used for detail masks.

use umodel to open the raw unreal engine files to understand the material concept.

mask for mini bumps as the game uses shared mini bumps, this is a mask for what parts uses it

Interesting...

By the way, if I were to submit the model, should I split the map into seperate channels like I would with PBR maps?
