Okie dokie, glass's posts have been cleared, lets get back on topic.
It's not that, interiors used a different form of shading than everything. Torque knew they weren't going anywhere, so it would make baked shadows that took a while to render, but looked nice (for the time). Looks like MBG uses the old shadowing system Blockland did back in beta 0002.
Yes but how could they have been alot like, sharper and smoother? Could torque have used a different shading engine?
