Painting around a hole

[We Know Motion]

Hello - I'm trying to add a decal to this wheel. I've tried adding color and alpha both a fill layer and a paint layer and can't get it to stamp where I want. Centered on the wheel. If I click on the side it stamps just fine but if I click center nothing happens.

I'd like to be able to have control over roughness, normal, and height too  - effecting only the areas within the decal. It's a full color decal if that helps. 

I'm able to get it centered where I want it with a projection but then I lose control over roughness, height, normal and those effects apply to the entire model instead of only the areas within the decal.

Any advice? 

Thanks!

Alt-Click on the side to get it onto the model as a decal, then use the manipulators to scale and position it over the centre hole

Hi thanks for the reply!

Yes that partially works. I can get it into position that way, however I can't control roughness, height for just the area of the decal this way.

You could add levels to the decal layer and use it to target any of the channels thereby giving you control over height/roughness etc.
The other way is to have those controls exposed in the sbsar decal

Interesting. I'm still a bit of a noob here so that might be a little over my head right now lol but I'll try playing with that a little and see what I can figure out.

Thanks for your help!
