The script im doing , Allow you to take cubemap shots, On walktrough Mode, and then you can place then in Static Objects (Don't move), of course the player won't be able to show in the reflection in this case... cause the texture is not refreshed..

For PLayer ( dinamic entity) the script let you take shot each 3 ( im not sure , seconds) refreshing the envirnoment cube map, based on player position.
