Show collidable geo from Tricoll

[snake-biscuits]

We can get interpret TricollTriangles now!
You can filter for TextureData to find invisible collision objects (nodraw tricoll, playerclip brushes etc.)

pretty much only useful for speedrunners, but if we can filter out decals & other non-collidable geo that'd be nice too

[snake-biscuits]

tricoll might also include static prop collision? idk tho

Nope! static prop collision is loaded "dynamically"
Presumably so props can be edited without recompiling

I plan to group decals & godrays / glow effect shapes into their own meshes
Same with transparent meshes (can take advantage of per-mesh transparency flags)

IDK if speedrunners have been looking for specific physics info in Blender
Importing static props could save them some time with routes that look clear, but aren't
Probably worth asking what upgrades people would like to see in the TF2|SR Discord

Might make sense to make loading Tricoll a part of the "Speedrun Preset" (see #3)
