For some reason, the skin for the X wing for the Imperial Assault mod has gone slightly....odd... Also, it changes as you zoom in :/ Anybody seen this before?
It looks fine in RenX BTW.
Another question, why do afterburners only show from side?
This is a random guess since I've never had this happen to me before.. but the first thing that comes to mind is that the skin is a DDS and whoever save it didn't use the "save mipmaps" option (might not be named that exactly, but its something to that effect). Which would explain the skins not displaying properly.. and then ALSO changing as you change distance.
The afterburner isue could be one of two things.. the easies tthing to check first is if the afterburner object has "2sided" checked in the w3d export options.
If it does and the problem is still around then you may want to delete the material applied to the afterburner object and recreate it again. I know I sometimes used to get odd bugs with muzzle flares similar to what you've described and normally recreated and applying the material fixed it.
