Four fixes for the user's "static / above the viewport / cavern clips it / doesn't
shoot off" report, each root-caused:
1. STATIC swirl -> now animates. The material's SCROLL (0.0 0.0 0.1 0.5) only
reaches the draw via a per-texture .met file (L4D3D.cpp:640) that tsphere lacks,
and the ramp-bake path leaves doScroll=false -- so the swirl was frozen. Set the
authored scroll rates (u -0.1/s, v +0.5/s) + REPEAT wrap on the sphere's draw-ops
at load, so SetTextureScrolling churns the swirl (the "spins around").
2. "Above the viewport" -> recenter. tsphere.bgf is modelled with its centre at
y=+8.25 (logged: center=(0,8.25,0.47) r=21.5); scaled x100-150 that threw the
sphere ~1000 units overhead. Translate the mesh's mCullCenter to the origin
before scaling so it sits ON the eye/anchor. (Added public-ish mCullCenter use;
l4d3d.h already exposes it.)
3. Cavern clip -> Z-test off. The arena is an enclosed cavern; a depth-tested 150x
sphere gets occluded by the ceiling/walls. Draw the POV overlay with ZENABLE off
(ZWRITE already off, so no depth pollution). BT_WARP_ZTEST=1 restores it.
4. "Fades in then disappears" -> expand-only. A respawn now starts in the EXPAND
phase (1->150 over 1s) so the swirl immediately bursts and blasts outward ("shoots
off into the distance"). The collapse (100->1) is the DEATH warp, not the
respawn. BT_WARP_COLLAPSE=1 plays the full collapse->expand.
Build + render + no-crash verified 2-node; expand warp fires POV/world. Still
deferred: the SetIsDead world-mask (black-out that makes the expand "reveal" the
world) -- carries the camera-coupling risk, add scoped if wanted.
