irrEdit light map question, didn't find answer in search

[juliusctw]

hello

I am rather confused with what to load with irrEdit light map, the tutorial says that it creates a dae collada file but it also creates irr file.

I loaded the collada, only the light map showed up and no texture, and when i loaded the irr file, there were bunch of extension problems. I didn't see this problem in the search, what's going on?

Are there other applications that can do light map for 3ds?
