Multi-Scatter LUT
Left half = Transmittance LUT. Right half = Multi-Scatter LUT. MS LUT stores Hillaire's ILLUMINANCE_IS_ONE-normalized values (raw ~0.001-0.04, would render as black); normal-mode display multiplies by 40× to match SkyAtmosphereMesh's luminanceScale. Debug modes show their raw [0,1] diagnostic output unscaled. Click a mode to switch:
