HiI generated some photo tiles using sbuilder. I just had summer season to start. Decided to get adventurous and try lightmaps. If I click summer and lightmap in the photo tile options box it generates the bgl and the two sets of textures, but FS9 crashes when trying to load the area at any time of day. If I generate the bgl again with just summer checked, then FS9 works OK, but of course black squares at night.Perhaps I am going the wrong way about it with lightmaps. Any help appreciated.editThought I should maybe point sbuilder to a different bmp for the lightmap on the photo background property tab. I edited original bmp and saved adding lm to the filename, but sbuilder says 'can not find xxxxlm.bmp' even though it is there.Mole man

Try setting the season in FS to summer before testing the scenery compiled with light maps is should work but only in the summer.I discovered that in order for FS not to crash when adding light maps to photo sceneryI must click all of the seasons in the photo scenery tab, it seems you have two choices:1. summer only without light maps2. all seasons with light mapsThis seems to be an FS limitation (or SCASM).
