Bug Cracks

Display cracks bellow overhead mountain.

The story goes that the deep mountain rock is very weak from all the bugs living inside.
If you see a crack on your floor, that means the infestation can spawn!
You can't even build any floor without it loosing the stability and cracking!

Or at least that's the lore of this mod.

Otherwise it is a simple visual aid to help plan around possible infestations without switching on the roof overlay.

This mod does not modify infestations or bugs. It shows cracks on the floor or walls bellow any "overhead mountain" (thick) roof.

Settings for terrain:
- Show cracks on burnables (which is unchecked by default). So, you can hide those cracks under the carpet, wood or hay at your own risk.
- Show cracks on sterile tiles (default checked). Even the sterile tiles are not stable deep inside a mountain. However, the cracks are thinner.
- Show cracks on shallow water (default checked). Cracks are not visible in the deep water, but can still be seen in shallows if this checkbox is ticked.

Settings for wall:
- Show cracks on walls (default true). Small thin cracks are displayed on walls if deconstructing them would reveal overhead mountain.
- Show cracks on rock walls (default true). Cracks are visible on rock walls if mining them would reveal overhead mountain.

To change color of overhead mountain tiles in roof overlay, install Roof Overlay Settings mod: https://steamcommunity.com/sharedfiles/filedetails/?id=2526879387

Compatibility:
Should be compatible with pretty much anything, because the mod only adds a visual layer. If some mods cause cracks to appear where they shouldn't, let me know.

Special implementations for mods:
- Compatible with Simply More Bridges (Continued): https://steamcommunity.com/sharedfiles/filedetails/?id=2012484790
- Compatible with Armored Floors (RimWorld <= 1.2): https://steamcommunity.com/sharedfiles/filedetails/?id=2011863224

Save file compatibility
The mod can be enabled/disabled as needed, again, it adds only a visual layer.

Performance concerns
The mod adds a few dozen of small textures. This should mainly affect load times and GPU memory. The crack placement is recalculated when the related terrain section is modified.
