No diffuse overlay weight option
There's a product I've been using for quite a while (sole blusher map from Necdaz, in case anyone happens to be familiar), which is added to a model by going to the surfaces tab, selecting the legs, and then loading the map on the diffuse overlay weight section. On occasion, I get a model where there is no diffuse overlay weight option available on the legs.
I haven't been able to figure out a way to use that sole blusher map on those models. Is there any way to get the diffuse overlay weight to show up? Or is there some other way I could possibly use the map on those models? I'm not sure if this is something I'd have to use LIE for (which I've never used before) or something. I'm a relative noob when it comes to Daz Studio, so I'm not sure if this is something that would be complicated to do or not.

The shaders are either PBRSkin, or a custom network.
Unfortunately, i have no idea what channel to use instead, and can only recommend eithr using LIE, a geoshell, or a decal.
Might try the makeup channel, but i'm not going to guarantee that one.
