3Delight surface and lighting setup for simple geometry

knuckledusterharris_b01188de76

In 3Delight, what is the best way to set up surfaces and lighting for the following scenarios? In other words, I want to use models with the simplest geometry possible, dialing in surfaces instead of using UVs when possible, but I want good lighting results.

A: Simple plane with four vertices and one surface (for instance, a wall that has wallpaper texture, or simple paint color).
A1. With texture loaded to the base color.
A2. No texture, using only the surface characteristics as dialed in (is this even possible?).

B: A complex plane with a subdivided mesh of many vertices or a cube/sphere/or cylinder with many faces.
B1. With a UV map (I'm assuming, since you can't apply a texture image to a multi-surface model without a UV map as I understand it).
B2. No texture, using only the surface characteristics as dialed in (I'm assuming this requires a pretty high poly-count model for good results).
