As a long time ue3 user, I ran into the unexpected problem with ue4 emitters where changing the actor/component scale does not properly scale the particle emitters in the particle system.
For example any particle emitter that uses any location module, or location based spawn module, will not scale properly.
Changing the emitter actor scale will only scale the sprites/mesh emitters, but not affect their relative locations to each other resulting in incorrect appearance at any scaling.
I see that setting an particle emitter to buselocalspace will change the behavior to what I would expect but setting everything to that is not an option since it changes other behavior of the particle emitter as well.
So is this a bug? If this was version 4.0 of the engine I would say it absolutely is, but here we are at version 4.21 and I’m seeing this issue and am rather dumbfounded.
