There are four different types of masks used in ETQW maps;
- The deploy mask - Mask to used to specify where deployables may be deployed.
- The MCP deploy mask - Mask to used to specify where the MCP can be deployed.
- The MCP Route mask - Mask to used to specify where the MCP may be driven before it is deemed off course.
- The Playable area mask - Mask where the player may travel.
They are all 128x128 pixel images, usually saved in the masks/mapname folder. The example map has all white masks so you can deploy and drive the mcp anywhere. Obviously this isn't ideal for a final map, so the white areas are usually built up using the mask editor. The paths to the masks are specified on the playzone.
