Strange, lodB files aren't referenced on lods.ini for the 993s but still included on package? Seems to go as far back to 1.5 release. Mentioning it just in case it was a mishap, but there's a good chance they were just set aside due to missing updates to match current lodA.
lights.ini mention Object1165, which is both the lodA oil arrow and all other lod's RR tyre, fortunately it doesn't seem to glow ingame.
Anyway, given the much lower detail of lodC I guess it was fortunate to leave the lodA file referenced twice as lod_0+1 instead of having the current C immediately as the lod_1 at a farther distance.
This can avoid csp treating the simpler _c kn5 as a real lodB suitable for lodA replacement up close, when auto lod swap optimizations kick (at max ~6 lodAs on screen) and lod.ini distances become ignored. Same for when users force lodBs for other cars in cockpit view (as in the zr1 example above).
OT: EAGLE 5, AmplifiedNL's v1.0 (2018-10-22) custom sound for the zr1 (
link) shouldn't crackle as much as the later v1.1 included in previous versions of this package, but it can still be problematic if another car using tatuus guids is present on session. To use it, you'll need to edit guids file and soundbank name to match current folder name.
