Am talking about decals. My plan is to add some colour and some text to add a bit more to the environment.
This is a simple material set up I have used.
Below is some examples of how and where I have added decals.
I think the decals worked well with my environment. They have injected a bit of colour into the grey. I think if I was to improve the environment further I could add some warnings or other signs onto pipe and assets.
