Important things:
- You can't see a flare model and a light itself from interior view. (I don't know why.)
- Material setting "lum" doesn't work for accessory parts.
- The light color affects 3d model, and 3d model reflects the light color. <= Very important
- Exterior model have two light sources. It's for an exterior view and it's for an interior view.
- Interior model doesn't have a light source.

You can't see the light (orangel_bgd) from exterior view because it doesn't have a flare model. And the light source itself is very very pin-point small lighting, so you don't notice it from exterior view, or it's just ignored by the game.

The position of an affect area of the light is a mismatch with 3d model. So you need to adjust the position of the light gradually. It's very stressful work. :-(


Honesty, I wanted to use a material setting "lum" but this is pretty good idea.
