// for different things. There's also render_mode for entities which determine blending mode
// and stuff.
// For ray tracing we do need to assing a material to each rendered surface, so we need to
// figure out what it is given heuristics like render_mode, texture name, etc.
// For some things we don't even have that. E.g. water and sky surfaces are weird.
// Lets just assigne water and sky materials to those geometries (and probably completely
// disregard render_mode, as it should be irrelevant).
