What is the Km tag in some .MTL files arising from Daz3D .OBJ export?

iancgbell

Some Daz OBJ export .MTL materials have a 'Km' tag specifying a single floating point value, usually 0 or very low.

I can't find this 'Km' tag documented in any .MTL specifications.

 Does anybody know what is is?

Thanks.

Metallic? It's usually 0 or 1.

I am told it is Bump Strength.
