tid_glass

Glass surface shader for the tides monoliths. Fresnel-weighted blend of a reflection and a tinted refraction of the shared sky_env sunset environment (identical to tid_sky's dome), a warm rim on silhouette edges (rim_color), and a tight sun glint. Renders on the transparent queue with culling off; front_facing flips the normal so both faces shade correctly. Alpha rises with fresnel and rim so faces read solid at grazing angles and nearly clear head-on. Palette properties are shared with the other tid_* materials from one table in the part module.
