finally after using 2.7GBytes of memory and maybe 1 hour CPU time I have a scene which is lightmapped very well. However, I want to change (Blender) some small things in the scene, then export and reuse the cached lightmaps. But somehow walktest refuses to use the old cache. I think it should be possible to reuse such light-cache if I dont´t add objects or similar.
Is there a trick to trick walktest? I also tried to put the cache into a ip, only changed the world-file in a old zip etc. but with no luck.
Hmm... If the changes are only minor it should be possible to reuse the cache. The changed objects will not have correct lighting but otherwise it should work. What kind of changes did you do? Did you change names of the objects or sectors perhaps?
