lightbake one object to fix lighting bug ...

Hello,

I've done a quick search for an answer to this - but I'm on a deadline and I need a quick response - so I appologise if someone has already asked this.

I have just done my 'final' bake for this project 6hrs 45 min (over night), and due to a FBX import issue, one piece of mesh (a rather large one) of a single fbx file had been baked incorrectly. I have had issues with FBX re-import not updating Lightmap UVs properly (another issue entirely, and will post about it later).

I now need to re-bake and I don't have another 7 hours to spare. Can someone suggest and alternative workaround? I'm not a newbie with game dev - I've been doing this for close to 13 years, but only been working with Unity properly for about 6 months. So I do know that you have to bake and entire scene for lighting in Unity, and that static lightmap objects will be evaluated for a bake... but I don't have the luxury of time to re-bake the entire scene to fix one mesh item. I'm using a custom beast settings xml, and I have tweaked the settings to give me the best result for the time and size of the scene.

suggestions (yelp)?

Cheers, D.
