Sorry for the confusion with obsolete issues in the tracker I closed them all now.
I’m developing Liquidiser for use with my game which currently uses .m3g format with an XML .inf addon for things which are not supported by m3g. It’s a one-man effort and I add features as I’m using Blender for more and more content creation tasks and/or add features to my engine so there’s no grand plan to support everything that Blender can do although that would be nice Said that, patches or bug reports are very welcome, perhaps even a feature request or two but I’m not promising anything with those
Anyway, if you need any help with Liquidiser just shout!
@mifth: you can certainly do that. I just added support for 2.62 which changes the way meshes are stored in .blend files (BMesh branch changes) so for time being it’s future-proof Proper support for most types of lights will land in the trunk in a few hours.
