maxscript bug in .gi_irradmap_preset

[davemcd]

I posted this ages ago before the list got hacked so i thought I'd repost it.

basically the .gi_irradmap_preset flag only changes the number of the drop down list and doesnt propogate the irradience map settings with the actually settings... basically there seems to be a missing callback that changes the settings if the dropdown list is affected via maxscript.

Cheers
