I can't think any better way of posting this with images and stuff. This is a suggestion, not a bug.
In the editor parts with high smoothness have a reflection that makes them look very weird. I think they're clouds, but with the grey background they don't feel right.
I see two problems with this:
- It's a bit unconfortable to edit a craft that looks bad to you while you're working on it
- It's hard to know how it's going to look once you launch. The difference is astonishing
