Right now, you can adjust the hue of a hill or basic shape, but not the color saturation. It may seem like a small detail, but if you want to add terrain to a sunny Ipsilon environment, there's no way to make the hills blend in with the white ground. EDIT: I figured out that it can be done manually by entering the hex code of the exact color you want, but to make it blend in with the flat white, you'd also have to get rid of the yellow markings on the hill. Getting it to blend in with a grassy surrounding environment presents a similar problem. It would also be nice to have mountain ranges like in the Tolbrynd environment, skinned like the snow-capped Ipsilon Mountains (with the sunny skybox, too). I know there are small individual mountains that can be skinned that way, but they don't lend themselves to climbing as well. With snow-capped mountain ranges, greenery could be added around the bases, and wind and clouds could be added to the top, to make it feel like you've scaled a great height to get there. Environmental aesthetics have always been a strong point of Besiege, so I think this addition would be a significant one. As with all of my suggestions, any feedback is appreciated.
