Hi, sorry i was able to fix it. I sadly did not catch you deleting the back faces of our booleanhelper object so it made the projection invalid. However i was able to fix it, thank you for responding either way!
Update: If I change the value of the mix node that is connected to the attribute node and the color ramp then the grime shows up. However if i change it on the material i appended from you then nothing changes.
It’s just that your startups always baffle me at first. I finally got the hang of where you started in the 3d view and such. Outside of always having a different startup file and nodes and sculpting tools that others might not have you really are a fantastic teacher and your material forge series is probably the best series ive gone through so far.
Well, its something i don’t quite understand myself and i sort of already scraped the blend file a long time ago. Sorry for wasting your time, if you can you could just delete this question.
