Viewport goes dark when not looking at particle effect.

Basically I have a room with a fire in it. If the fire is not within my view, the particle will no longer display light for the room, causing the room to go black. What is the fix for this? - that might be some help to you mate :slight_smile:

I think you need to increase the bound scale of your particle emitter so that it wont disappear when its bounds are out of screen. :smiley:

Yeah it’s a bounds issue, your particle is probably being culled. Use ‘Set Fixed Bounds’ and make them larger and the effect should stay on.

Bear in mind, the bounds optimization is there for a good reason. In some cases like this it may be more efficient to place a light in the world with a light function that simulates flickering light.
