Titanfall Map Decompile Error "Couldn't find static prop struct for appId 1454890, version 12, size 84"

[POLY-021]

I'm attempting to grab static props from Titanfall 1, and BSPSource does have a "Titanfall" option for the BSP format. However, when I try to export, it doesn't export things properly and spits out a 0 kb file. Any help?

I can confirm that this failure to write lumps also affects NEOTOKYO maps, and is version-specific to BSPSource 1.4.3. Version 1.4.2 does not fail to do decompilation in this way.

@POLY-021: I don't really now to what degree Titanfall 1 was ever supported. There is code to at least load the bsp files of titanfall, but not really any to handle writing the data to a vmf. I'm not familiar with Titanfall, but I think their map format greatly differs from normal source games, so I'm not sure if the maps could even be convert to vmf files that the normal hammer editor can use.
If I have more time on my hand, I will have a closer look at this.

@SC1040-TS2: I don't know NEOTOKYO, but if it's not a game based on Titanfall, your issue will probably be something unrelated to this. Can you share what exact error you're getting with 1.4.3 but not with 1.4.2?

Afaik Titanfall 1 wasn't ever really supported, iirc ata4 got some info on lump names from cra0 back in 2014.¹
The Titanfall 1 format is significantly different to the rest of the Source Engine's .bsp formats

I've made a .map decompiler (Quake equivalent of .vmf) as part of bsp_tool
So it is possible to decompile Titanfall maps, though the only editor for Titanfall .bsp currently uses the .map format²
The only Source Engine game I can think off with limits that could handle Titanfall maps is Momentum Mod

Skimming through bspsrc, I can see trying to support Titanfall next to all the other Source Engine formats being a lot of work.

Titanfall 2 isn't too dissimilar to Titanfall 1, but my decompiler currently breaks trying to link brushes to entities.
Most of Titanfall 2's geometry is displacements / meshes baked into the .bsp anyway, which we haven't yet reversed.

Apex Legends (mentioned in #59) removes almost all the lumps used when decompiling Titanfall 1 & 2 maps.
While MRVN-Radiant can create some basic Apex maps, we've yet to decompile any Apex Legends maps.

I don't know NEOTOKYO

NEOTOKYO³ uses a standard VBSP v20 format, similar to Team Fortress 2
Idk why there would be issues decompiling any NEOTOKYO map

That's good to know. In that case, I don't really have much motivation to try to add some kind of support. Currently, bspsrc assumes a common ground between all bsps with contains things like brushes, brushsides, texdata, etc. (Basically what's in BspData.java). So trying to support Titanfall in bspsrc current state would indeed probably be a lot of work.

I already got a suspicion that it has to do something with staticprops not being read correctly. #164 has the same issue. The 'generic' static prop version definitions in bspsrc seem to be incorrect for the majority of games. I really need to get an overview of what kind of engine branches there are and how their staticprop versions are defined.

Thanks for mentioning your bsp_tool though. That's going to be very helpful in cross referencing all the static prop definitions.

Do you perhaps also know how accurate the StaticPropLump_t definition on the BSP File Format Wiki is? Because it doesn't match what bspsrc currently has.

[snake-biscuits]

The VDC wiki definition looks accurate to me, tho it’s been a while since I implemented static prop definitions in bsp_tool
Some games differ on a few versions,
v7 & v6 are different for a handful of games iirc
