I created a blueprint with two components. A particle system, and a static mesh. The particle system generates particles with actor collision. Inside the blueprint the particles will penetrate and fall straight through the mesh even though collision is correctly set. If I take the same mesh, and the same particle system and had them directly into the level the particles correctly collide with the mesh. This seems to be an obvious bug. Please help, and thanks in advance.
Particles system inside of the blueprint will not collide with a static mesh that is also inside of the blueprint
Most of the time i avoid handling it from inside the PS and i do it in the BP.
In your instance Actor Collision module has an “Ignore Source Actor” ticked by default. Have you unticked that?
That was it! Thank you.
