I want to really simple layout to serve as a training simulation. The idea is that I think people will find it easier to learn combat if they can role play, but in world they're in a simulation.
I also wanted to try making a map fast. In the past it's been a long, slow process. This is a partially built trolley in a factory that players can use to trying out tactics.
I was mostly thinking of the difference between types of barriers. The light grey blends in a bit, I wasn't sure it belonged in the scene or came from the source image.
The different shades of grey does have one advantage - it should work fine for colorblind people. I was thinking maybe dashed lines might be a good way to delineate soft or incomplete cover.
It sounds like I should darken the light grey so it's clear that it's distinct from the background.
