In physical photography, high-intensity light sources do not immediately clip into flat white shapes; they roll off with a soft, photographic S-curve shoulder. Standard WebGL clamping without tone mapping produces harsh, blown-out artifacts.
1. Why ACES Filmic Is Essential for 3D Commerce
Setting toneMapping to THREE.ACESFilmicToneMapping compresses HDR specular values above 1.0 into an organic, cinematic curve. Leather highlights maintain texture depth rather than washing out into clipped white spots.
