FLOORS (Chasm)

floors.xx

Chasm: The Rift uses a floors.xx (where xx is the map number) file which holds the floor and ceiling tile textures within it. A floors.xx file can hold up to 64 textures, and these textures can be applied to floors, ceilings or both.

floors.xx files are used for both the DOS and 2022 Remaster versions of the game.

Chasm Floor Editor

Kostas "Bad Sector" Michalopoulos has written a tool that can be used to add, remove and rearrange these textures. Additionally, it can mirror, re-mip and apply palettes. It can be downloaded from Kostas' website at: http://runtimeterror.com/tools/chasmfe/
