tes_wall

Surface shader for the tesla hall's paneled-steel walls and roof deck. Picks a paneling plane from the dominant normal axis, draws corrugation ribs, sheet seams and girt lines, streaks rust downward, darkens the wainscot band and the eaves, and lights everything analytically (high-bay lamps, coil flood, discharge flash, strike impact, warning beacons) with distance fog. Driven per-frame by preseed.parts.p_tesla via the ptes_wall material.
