I select a whole bunch of stuff from my scene, about 60 objects, then i use external lightmapping tool to export them to, in my case 3dsm. but only a few objects are exported and there is no, as i can see, logical pattern to what object are exported and not. I have successfully used the External lighmapping tool before with fewer and simpler objects. So i wonder why this is happening and how i can get all the objects to export.
Any help would be appreciated!
