Crash during non-continuous lightmap bake in b13 with specific scene.

Unity Engine

FWIW this didn’t occur in b12 (to the best of my knowledge). Entered as FogBugz case #649026.

Crash during non-continuous bake. Crash log attached. All defaults used, except Baked Resolution set to 15. Occurs when baking Non-Directional, Directional and Directional Specular light maps.

Top of call stack is always:-
