The default studio environment's level-preserving mean of 1 acted like a 100% white Ambient light: with only the Environment light on, a white floor rendered at full white (95% of the frame saturated) while its shadow core went to pitch black — a fog over the scene, nothing like After Effects' default. Three changes bring the look in line, CPU and GPU alike: - The default environment is a dim studio now: a solid-angle-weighted mean of 0.3 (and a stronger key gradient), so a white floor reads a mid gray and the light's colour x intensity still scales the level. - The shadow occludes only the image's directional (key) fraction of the light — |sum of dir x radiance| / sum of radiance, computed beside the dominant direction and carried in the scene — so the fill keeps shining inside the shadow: an area-light shadow, partial like After Effects' (a lone bright spot on black still shadows almost fully; a uniform image not at all). - The environment shadow map's penumbra has a floor — eight output pixels, or four map texels where those are coarser — because the map covers the whole scene bounding sphere rather than the view, and its texels would otherwise stair-step the edge (all the more in a draft render's flat 512 budget). Shadow Diffusion widens it further, as before. Tests: the key fraction tracks directionality; the default keeps its dim level, its direction and its key; the default and a bright key both shadow the floor (the default partial, the key deep) with Cast Shadows off lit everywhere; and the full look — a mid-gray lit floor (no fog), a partial core, and a soft edge ramp in quality and draft renders alike.
