Yep, you need the gmt importer script, import the startlights.gmt (btb should export all the startlights as one gmt, if not then import all the startlight.gmt's). Then go to poly submode and select a poly on the light glow's on the extra lights, then select id, then change the material id to the relative one from the default start lights. There are 4 in all, green light and glow, red light and glow. Then you need the gmt converter from isi to export it back to gmt. Or if you want to repack them into an xpack, you can just export them as 3ds.Thank you mianiak. I´ve never used SimEd before. How can I import the startlight and how can I change the materials ? Is there a way to edit the startlights in 3dsmax ?
