- V toggles the authentic cockpit eyepoint <-> the chase camera. Both eyes
coexist; DPLEyeRenderable::Execute now writes the VIEW only when it IS
mCamera (unconditional writes let the last-executed eye stomp the toggle).
- EyepointRotation is a real zeroed EulerAngles member on Mech (was bound to
the shared junk attrPad -- the eye composes this attribute into the view
EVERY frame, so the cockpit camera was rotated by garbage: the canted
horizon, then the black screen). The eye-slew systems write it later.
- The cockpit eye mounts at the eyepoint's REST position with a clean upright
forward basis on the tree root (the live joint chain fed it the site tilt +
torso pose; authentic pitch/yaw is the deferred gyro eye chain).
- The inside view swaps the player to the INSIDE skeleton mesh set
(SkeletonType_A): 19 body segments hide, exactly one mesh remains --
blx_cop.bgf, the authentic cockpit canopy shell around the eyepoint. It
currently renders as a black enclosure (the black-screen report), so it is
HIDDEN pending its interior/punch-material rendering (BT_INSIDE_COCKPIT=1
shows it for that work). Damage gstates respected in both directions;
RemakeEntity keys off the DISPLAYED skeleton.
- Dev: BT_START_INSIDE=1 starts in the cockpit view.

Clean, self-contained extraction of the BattleTech-specific work from the
reverse-engineering workspace -- engine + game + content + build, with nothing
from Red Planet or the raw archive dumps. Builds green (Win32) and runs the
single-player drive->animate->target->fire->damage->destroy loop out of the box.
Layout:
engine/ MUNGA + MUNGA_L4 shared 2007 engine, carrying our BT render/loader
work (bgfload/L4D3D/L4VIDEO: BSL bit-slice decode, LOD/ground/shadow
models) + image codec; the minimal rp/ headers the audio HAL needs
game/ reconstructed BT logic + surviving-original BT source + fwd shims
+ WinMain launcher
content/ full runtime tree (BTL4.RES, VIDEO/, GAUGE/, AUDIO/, eggs, BTDPL.INI)
docs/ format specs + reconstruction ledgers
reference/ raw Ghidra pseudocode (recon source-of-truth) + decomp exporter
tools/ MP console emulator + map/resource scanners
One top-level CMake builds munga_engine lib + bt410_l4 game lib + btl4.exe.
All paths relativized (186 fwd shims + ~437 CMake abs paths -> repo-relative);
DXSDK is the one external, overridable via -DDXSDK. Verified: builds to a
byte-identical 2.27MB exe and runs combat (TARGET DESTROYED, 0 crashes) against
the bundled content.
