Particle color always in black when used in world

[anonymous_user_0f2dfaf0]

Hello I’m creating a particle system to simulate the spray behind a vehicle but I’ve faced a very strange problem. For example, here I set the color of the particle emitter in red. Just as the figures below showed, they seem perfect in particle viewport and also the blueprint component viewport.

But when it is used into the world, the particle color will be in black. And no matter which color I set on the particle emitter, it’s always in black.

But if I use the same particle emitter on another map/inside another world, it shows the same effect as inside the particle system viewport, just as the figure below:

Can anybody explain the reason why it’s like that? Is it because of anywhere in wolrd settings or else? How can I solve this problem and get the perfect effect inside the world when using it? I’m totally new in Unreal Engine and any help at all would be greatly appreciated. Thank you very much!

Hello!

It seems that somebody had a similar problem as you

Particles turn black on simulation or play

I had a similar issue just now and searched for an answer and found your post. I think I figured it out. - select your particle emitter and go to Lighting - find “Indirect Lighting Cache Quality” Try changing it to “ILCQ Volume” That solved an issue I had with particles turning back. I kept all the other lighting stuff default.

If that does not solve the problem, it could be a lighting problem, maybe the directional light has a large value (too bright) on the map where the particles turn black.

Hope this helps!

Hello, thank you for the answer. I’ve found the reason of my problem. You are right, the directional light and sky light have a too large value in my scene, so that the particles turn black.
