I'm testing Fusions's particle system and stumbled upon a strange behaviour of the turbulence force:

When I activate motion blur (have set up MB on both, the pRender and the Renderer3D equally) the strength of the turbulence force drops dramatically. I can compensate by pushing it up by a factor of 10 or higher - but then when I turn MB off again temporarily (with the time rule button, to speed up rendering) the force is way to big again!

This only happens with the turbulence force, not with e.g. point or directional force - those stay the same whether MB is on or off.

Am I doing something wrong here? Is this a known issue?

Known issue. As you discovered, you can work around it, but yes, that's the way it works currently.

Thx for confirming (at least it's not me )

I'm on 18. Still hasn't been fixed?


EDIT: Sub-frame accuracy also affects the turbulence seemingly the same way as prender's motion blur. What is going on? xD
