COLL records are "collision layers". A collision layer is essentially an invisible box around/near NPCs/objects/camera, indicating different kinds of checks if they collide with other boxes.
If a box of type A collides with a box of type B, and the formid of A is in the CNAM field of type B then some kind of action is triggered.
| C | SubRecord | Name | Type/Size | Info |
|---|---|---|---|---|
| + | EDID | editorId | zstring | Editor id |
| + | DESC | unknown | lstring | Description (presumably for CK) |
| + | BNAM | unique id? | uint32 | Unique id (within COLL), may be used instead of FormID to reference internally |
| + | FNAM | debug color | rgb | Debug Color |
| + | GNAM | flags | uint32 | Flags
|
| + | MNAM | name | zstring | Name, always same as EDID |
| + | INTV | interactables count | uint32 | Count of interactions in CNAM (if 0 then no CNAM field) |
| - | CNAM | interactables | formid[] | Collides with..., End-to-end COLL formids, total count INTV. Presumably these are to indicate if the 2 collide there is something to check/do. |
