fix(shaders): a surface marked as metal in specgloss but with an albedo darker than any real metal is lit as the painted or dirty dielectric it stands for, with its diffuse back and its highlight held to 0.06, instead of going black without a diffuse term, and a metal reflects its surroundings at least at half strength whatever the alpha of its normal map says, since its reflection is all of its colour; materials without specgloss stay as they were

fix(shaders): the highlight of the sun is multiplied by the cosine of its light, so surfaces no longer glare milky white under a low sun; headlights light a surface with 1.35 of its diffuse colour and add a GGX highlight of their own scaled by specgloss and param_specular instead of multiplying the whole light by one plus param_specular; normalmap, parallax, detail, shadowless, sunless and default_detail materials read param_glossiness as a Phong exponent, roughness = (2 / (n + 2))^1/4, instead of 1 - 1/n or a fixed mirror

feat(render): ambient occlusion with bent normals darkens only the light of the surroundings instead of the whole image, so the sun and headlights keep their full strength; the occlusion and the bent normal of the previous frame are reprojected into the lighting of the scene, with the motion of the camera and of every vehicle and cab taken into account and with depth checks against disocclusion, the ambient light follows how much of the sky the bent normal sees, and reflections of the environment are occluded where the cone of visible directions around the bent normal cuts off the reflected lobe, only where the occlusion is clear enough that open flat panels and windows keep their grazing reflections

fix(shaders): parallax mapping reads its depth from a mip about four texels per pixel coarser, filtered bicubically where the hit is refined, so the relief no longer breaks into stalactites and the edges of stones no longer step along the texel grid of the compressed depth; it takes 16 to 64 layers by the angle of view and six steps of refinement, casts the shadows of the relief from the sun over the sun light and darkens the hollows deeper than the mean depth of the texture while lightening the tops, so the mean brightness of a surface stays the same
