* During pathfinding calculation OniSplit creates a new folder called "temp" and a subfolder "grids". There again is a file "''levelname''_grids.dae". That file contains ''rooms'' with textures "bnv_grid_''N''.tga" marking obstacles in the pathfinding. ''Ghosts'' will have a transparent texture "'''_marker_ghost'''.tga". You get those things also when you export a level. Transparent ''ghosts'' make it easier to see the rest of your level if you have many of those planes. | * During pathfinding calculation OniSplit creates a new folder called "temp" and a subfolder "grids".
