I Narrowed it down to: For some reason bmap_create seems not to be able to load bitmaps from a path, but can load them direct from bin folder OK.
Path: public static String textures = Application.StartupPath + @"\defaults\textures\"; and use like so: water_bump = BMAP.bmap_create( textures + "waves2.tga" );
All other load or create commands load from these types path fine, but bmap_create does not.
Would not seem to be a wrapper problem though.
