Build lightning keep crashing

[lebaje]

Hi everyone, i have a huge pb and can't figure how to solve this!

trying to build the ligh but it keep crashing at 16%. but when i'm selecting some of the staticmesh and build the light, its working?
And its not because its out of memory. So i don't know what could it be!!

Anyone can help me with this?

[JulienCoffin]

How complex are the object in the scene? How many polygones are there? Are all the objects unwraped? Try to start with some basic setting just one spot light, see if that works first. Just a couple ideas, we need more info to help as I cant read this yellow script thingy : )

[lebaje]

I figure it out...kind of

its the landscape that was crashing everything. Didn't find the way yet to fix it, but by selecting everything execpt the landscape, i was able to bypass the pb. One thing, how do i exclude the foliage from the built light??

[lebaje]

Aright, the problem was that i hmmmm...abused... a little bit of the foliage. So its was the grass that was crashing the light baking
