See HERE for a few tools for two-way conversion of grids.

The editable format is quite intuitive ASCII.

Tile types are assumed to be 0-9.

"inside" means towards the inside of the warehouse

"west" is X+, "north" is Z+

bottom floor is 1, top floor is 3 (US/Japan)

Other BNV

6, 26, 50 (impassable tiles on north side)

THESE are some observations made with pathfinding grid for others to see, because adjusting of some BNVs is IMO neccessary part of modding levels and this info can help. Some statements may be wrong, so please correct mistakes if you find any.

9 - red tiles (IMPASSABLE):

• are ignored when AI2 is in MELE mode (AI2 character will chase you into "red field", that is some larger area filled with red tiles, if it is close enough to you to be in MELE mode). That is why sometimes happen that you are close behind wall and AI2 character desperately runs towards wall on the other side - red tiles, indicating some obstacle, are ignored as AI2 char is in MELE mode.
• leave AI2 ability to fully run its MELE profile if it is in "red field" and you are close enough
• block pathfinding completely (if you trap AI2 character somewhere in "red field" and you "teleport" away, it gets stuck and won't be able to chase you unless you come close enough to make it run some MELE move so it can move). This applies on both pathfinding (chasing enemy thanks to the dynamic flags) and vector-forced movement (so AI2 character can't dodge firing spreads if it is inside "red field")
• if AI2 is not inside "red field" and you are not close enough (so AI2 is in pathfinding or patrol mode), then red (impassable) tiles work as a wall for AI2 chars. Where are red tiles there AI2 NEVER runs (again, never if you are NOT TOO CLOSE) and it tries to find its way around it if these red tiles are in the way. If no other way is possible, then AI2 simply stops right before the red line. That is what makes AI2 characters stop near wall (and stare into it until gunfire stops) when they are dodging projectile ranges/firing spreads. They want to go this direction but there is wall. Because pathfinding mode is not active when AI2 chars are dodging gunfire, they get stuck near wall as red tiles are in way and calculated vector of movement still points towards wall.
• BUT if angle between vector of movement (for gunfire dodging) and these red tiles is small, AI2 can "slide along" the line of red tiles. I don't know how big this tolerance is ^_^.

ONLY a theory

• Also it looks like these red tiles are taken as "wall" when it comes to projectiles/spreads. So maybe (unconfirmed) AI2s try to run so some line of red tiles is between them and shooter.

/ONLY a theory

8 - orange tiles (DANGER):

• are NOT ignored when AI2 is in MELE mode (AI2 does some actions, read below)
• restrict AI2 MELE abilities. According to pre-computed reach of technique (it must be stored somewhere), it is labeled as WORRY-FWD (so-so, AI2 will almost meet orange line if it executes it, these techniques have their weight watered down by engine, algorithm is unknown) or DANGER-FWD (AI2 will exceed orange line if it executes this technique, so engine disables it temporarily-weight 0 I guess).
• if enemy is INSIDE "orange field" or BEHIND it and if AI2 character is close enough to enemy to have its MELE mode active, engine allows only jumping techniques to execute. Jumping techniques are those which have jumping position move in them ([OBD:BINA/OBJC/MELE/MoveList/Position]], numbers 4,5,6,7,8,16,17,18,19). If AI2 char is inside "orange field", then only jumping technques are allowed. If AI2 does not have any jumping technique, it will switch to pathfinding mode and then (inside orange field) it keeps switching between pathfinding and MELE.
• do NOT disable pathfinding. AI2 characters will try to avoid orange tiles same way as red tiles, but if there is no other way, they will go through. So you canot "trap" AI2 character in orange field, it WILL find its way out.
• when it comes to gunfire dodging, orange tiles serve the same as red - if AI2 runs towards them while dodging, it stops and stares (if vector of movement still points toward orange tiles). Inside orange field AI2 can't dodge gunfire (same as red)

7 - dark green tiles (STAIRS):

• seem to be ignored when AI2 is in MELE mode, it is probably patrol/pathfinding-only
• AI2 tends to avoid them, but if no other way is possible, it goes through it (probably insurance that AI2 char will always choose the shortest way)
• stop gunfire dodging the same way as red tiles do (but why? it is a bit weird)
• probably serve as "here comes stairs" mark

6 - dark blue tiles (BORDER 4):

• seem to be ignored when AI2 is in MELE mode, it is probably patrol/pathfinding-only
• serve as mark that some edge is right the step ahead. If AI2 needs to run somewhere (patrol/pathfinding mode!) and meets these tiles, it will try to run along them. if AI2 is already in "dark blue field", it will run out of it and will try not to go into it.
• stop gunfire dodging the same way as red tiles do

5 - blue tiles (BORDER 3):

• same as tiles 6 IMO, maybe it only tells AI2 that it is "quite close to the edge"

4 - green tiles (SEMIPASSABLE):

• seem to be ignored when AI2 is in MELE mode, it is probably patrol/pathfinding-only
• AI2 tries to avoid these tiles if it meets them, but if no other route is possible, it will cross these tiles without problems
• do not limit gunfire dodging

3 - lighter blue tiles (BORDER 2):

• seem to be ignored when AI2 is in MELE mode, it is probably patrol/pathfinding only
• AI2 can run straight through these without any problems, it does not limit gunfire dodging as well
• probably they tell AI2 that "edge is close"

2 - lightest blue tiles (BORDER 1):

• same as tiles 3 IMO, maybe it only tells AI2 that "edge is around"

1 - lighter green tiles (NEARWALL):

• seem to be ignored when AI2 is in MELE mode, it is probably patrol/pathfinding only
• probably just tell AI2 that "obstacle is close", it can run through them without any problems
• do not limit gunfire dodging
