Hey,

need help with why the bounding box info of a mesh that I scaled (but also when moved) does not change/update.  
I just need the first vector of boundingBox.

Hi!  
It works in 4.2.1 so I suggest you to report this as a bug.

It doesn’t work for me in 4.2.1 either? 😮

This is spooky 😃 👻  
Give me a minute, it seems to be browser or platform specific, will do a few tests…

@Regit I overlooked it sorry 😃 My bad…

The world vectors are updating, but the locals are not. I believe, by scaling the mesh the boundigBox should scale as well, however if you call `boundingInfo.scale(number)` it updates.

@sebavan Can you confirm whether it should automatically update the local vectors when scaling or not? Thanks!

It should NOT. The local vectors are, well, locals 😉 Which mean they are BEFORE the world transform. They only change if you change the inner geometry.
