Particles are black

Development Architectural and Design Visualization

Hello everyone !

I have a problem using particles in ue 4.24.1

When I use a blank architecture blueprint the particles appear black (picture)
I guess it’s some kind of a lighting problem maybe.
Does anybody have the same problem ?
In the standard game blank blueprint they work fine.

Thank you !

I have the same problem in UE5, but only in a certain level where lighting consists of : Directional Light, Sky Atmosphere, Exponential H Fog & Sky Light and I haven’t figured out how to address this problem.
