Just like with Characters, Adam provided me with concept drawings of props from different locations of the world. I learned a lot about mapping outside 1-to-1 UV space and maintaining the scale of textures through creative mapping.
Having your props created at certain dimensions, with correct pivot points and on grid is a necessary task, so you'd be able to 'snap' things into appropriate place within the engine.
After establishing a light-rig, the props must have the least amount of shading errors, thus you must adhere to having an appropriate topology at a logical amount of poly density.
