I’m modelling a matt-black plastic cylindrical object (it’s a rain gauge, actually) which is outdoors. Part-way through my animation there is a rain shower, and I would like the plastic to look wet. I tried turning on ray-tracing, but that makes the object pick up a lot of blue from the world colour, which is not what I want. Can I somehow make my object ignore the world colour (but I still want a blue sky)?
Or am I going about this wrong? Should I be using reflectivity and/or specularity (I fiddled with them a bit, but didn’t get good results)?
I don’t need anything hi-fidelity here, just a visible difference between dry matt-black plastic and wet black plastic.
Thanks for any help you can give me.
