3d Paint not showing up

Hello and I am sorry if this has been covered but I have imported a few hard surface models from Zbrush to play around with the 3d Paint feature. I applied an aluminum material to them and then when I go through the steps (And I followed the video tutorial exactly) and start painting I get nothing. But when I haven’t applied any material I can see it. Can we not paint on a model that already has a material applied is my question or problem I am having.

Hey Derek, can you upload a screen shot of your material graph and image so I can get an idea of what might be happening?

sorry for the very late response but there is the Material graph

The Graph looks good. Can you show a screenshot of the Material / Texture window where you have the paint settings?

The issue most likely that you have Metal Type: Measured vs Metal Type: Color
