Players: "the actual enemy mech in external view is not showing darkened armor panels". We swapped destroyed LIMB meshes but never darkened a panel. The 1995 game darkens armour through the MATERIALS. MakeMechRenderables (FUN_004cef28) built, per (damage zone, material), a watcher FUN_004573e4(material, &zone->damageLevel, 0.1f) that snapshotted the materials

|
# The 1995 renderer lerped every material a damage zone paints from its authored
|
|
# colour toward 0.1x as that zone's damageLevel ran 0->1 (FUN_004573e4 built one
|
|
# watcher per (zone, material) from the mech's .DZM list; FUN_00457784 re-pushed
|
|
# the blend on every change). Our renderer swapped destroyed LIMB meshes but
|
|
# never darkened a panel -- "the actual enemy mech in external view is not
|
|
# showing darkened armor panels".
|
|
#
|
|
# Two legs:
|
|
# self -- self-damage one named zone on the player's own mech; the cleanest
|
|
# read of the level->brightness chain (deterministic, one zone).
|
|
# enemy -- walk up to a spawned target and shoot it: the REPORTED case, an
|
|
# enemy hull darkening under fire, with screenshots to pixel-verify.
|
|
#
|
|
# Verdict lines:
|
|
# [armor] zone N '<dzname>' -> M draw op(s) .DZM list resolved onto geometry
|
|
# [armor] '<mat>' zone N level a -> b (brightness kx) level reaching the ops
