Niagara and Movie render queue with alpha

JDARRAS · September 28, 2023, 2:49pm

I place a niagara particle system in a blueprint that I put inside my level. When I render with the “movie render queue” > no problem, I see my particles clearly.

I modify the project setting to accept alpha like this :

In my movie render queue preset, I activate “accumulator includes alpha”

When I render, I no longer see the particles unless a mesh is behind.

I don’t understand why, can you help me ?

Thanks a lot
JD

Hi! Did you solve this problem??

Not really ! I don’t really understand the problem.

Would love a solution for this as well. Using Ultra dynamic sky but I am not able to see the rain in my renders ( with stencil layers)

Try activating the Render CustomDepth Pass in the details panels and the Niagara System
