How to prevent players from building on certain areas?

[Ghost_Ship_Supreme]

Is it possible to make some flat areas in custom maps not buildable for structures?
I know there's darkness and contamination, but those can both be removed and make the textures change. I was wondering if there was either a way to make the special textures much less noticable, or invisible completely, or if there's simply a "no build" brush applicator somewhere? Or Should I instead just use darkness and disable beacons/make them hard to obtain?

In the mission editor 'Game' tab, you can disable the 'Decon' option; this will prevent players from removing contaminated terrain. There is no way to make special terrain types invisible, but it is possible to make an invisible no build area.
However, this method requires 4rpl; if you are already familiar with 4rpl, I would recommend running SetCellOccupiedCount on all cells in the area to prevent players building on that terrain. If you are not familiar with 4rpl, I think it would be much easier to just go with the contaminated terrain & disabled Decon option.

I've decided to use a bit of both. I'm going to use dark towers to prevent building along the outer walls, and possibly contaminant for the inner walls. Though it is really quite ugly... I wish i could at least change the texture of it from bloody pumpkin orange to a dirty wall water damage yellow, for my creeper lakes and whatnot.
I will simply have to prevent them from obtaining Liftic until later in the map, hopefully preventing early game cheese...
My solution to the dark towers is to manually increase the texture brightness, but i'm not sure what to do about the contamination.

You could try an image overlay in those specific areas? Or maybe a decal?

Note, lots of folks (including myself) have difficulty figuring out how to delete decals. So, just in case: You click on the decal, then a pane opens in the lower right and there's a"delete" button there. :)
