Hi there,

In cascade, you could filter the collision layer in the collision properties of your particle emitter.

I am trying to spawn particles from a skeletal mesh on impact, but if I have collision enabled in Niagara, they collide with the actor unless I disable “world dynamic” collisions on the actor, but this affects the ragdoll.

Is there a way to filter the Niagara particles to ignore certain collision layers/only collide with static objects?

Thanks in advance

P.s. someone else asked this question in May 2019 and developers said it would be added soon as a feature, does this functionality even exist?
