Is 29 (LUMP_PHYSCOLLIDE) really unused?

bsp_tool/bsp_tool/branches/respawn/apex_legends.py

Line 53 in 56c4251

UNUSED_29 = 29

Appears this is unused, but I'm not sure if that was just put there in a haste or is actually reality. I could not find any information on LUMP_PHYSLEVEL which I suspect may be the alternative lump which holds collision data.

Both Titanfall 1 & 2 store lump 29 externally in <map_name.bsp>.001d.bsp_lump
None of the Apex .bsp's I've checked have this file
I've checked the headers in mp_rr_olympus.bsp for lump 29 & it's empty, so it's not in the .bsp either
Best I can tell, the Apex Legends branch just doesn't use this lump

.bsps checked:

mp_rr_canyonlands_64k_x_64k   KING'S CANYON
mp_rr_canyonlands_mu1
mp_rr_canyonlands_mu1_night   SHADOW ROYALE
mp_rr_canyonlands_mu2
mp_rr_canyonlands_staging     FIRING RANGE
mp_rr_desertlands_64k_x_64k   WORLD'S EDGE
mp_rr_desertlands_mu1         WINTER EXPRESS?
mp_rr_olympus                 OLYMPUS

Interesting, thank you for the check!
Perhaps it's in the BSP but under a different lump? I did see a few unknowns in there.

I'm going to have a look myself in the coming days. I don't have Apex on PC currently.

I'll close as you've confirmed 29 is truly unused. 🙂

FWIW I plan to start investigating where collision is defined today (I finally d/l'd Apex on PC). I'll update you if anything. End goal is exporting collision to .obj or similar so it's viewable in Blender or similar.

I'll definitely be interested to hear what you find!
I'm slowly exploring more of the rBSP format, starting from the first Titanfall but I haven't touched physics yet
