Running 1.5.2 now, but this might have been a bug earlier, and I just never saw it.
I have a Krakatoa Geometry Test testing to see if some particles are inside of a Box. But I saw that my box really needed to be a trapezoid, so I put an Edit Mesh on it and pulled it into shape. But the Test still only tested the base Box, not the result with the Edit Mesh. Odd?
Confirmed. There is some sort of heavy caching going on.
For example, I can pick a different object (a sphere) and it still uses the cached geometry.
Then pick back the modified box, change its shape, nothing helps short of replacing the test with a new instance.
This is caused by the fact that since there is nothing animated on the stack of the object, the cache is never rebuilt.
A possible workaround is to add a Bend modifier on top of your geometry object, go to the last frame and SHIFT+Right-click the Arrow of the Angle spinner. This will set a 0 keyframe on frames 0 and the last one and invalidate the validity interval. As long as the “Animated Geometry” checkbox is checked, the Geometry Test will recache.
I will log a bug against this because picking a new mesh should invalidate the cache and rebuild it.
Also I would expect the checking/unchecking of the “Animated Geometry” to invoke a kd-tree update, just in case.
Thanks for catching that!
