+^ Variable^ Description |
+| ''path''| Image file to use as the reflection cube map for both interior and exterior spaces. Use this as a convenience if there is no need to separate between interior and exterior spaces. |
+| ''interior.path''| Image file to use as the reflection cube map for interior spaces. |
+| ''exterior.path''| Image file to use as the reflection cube map for exterior spaces. |
+===== Interior vs. exterior =====
+Doomsday will use the exterior reflections for objects in sectors that have a sky ceiling or floor. Otherwise the interior reflections will be used.
