I’ve been encountering this bug for months now when creating effects in Niagara, or maybe I’m doing something wrong: I have an emitter that emits sprites with a texture. The texture used doesn’t matter at all. But after the emitter starts playing and my particles spawn, after literally 10 seconds, the textures become simply terrible. Their brightness somehow increases several times, doesnt matter what color mode i used.. Even if I pause the effect, it still happens. When i change the preview scene profile - it will be good again Here’s a video: what the hell is happened?
So, I tested it in different projects, and this problem is observed there too. In general, the problem is reproduced in this case: you create a minimal Niagara system, create a minimal emitter and add a burst with 1 element there, then in the preview scene profile, select Epic Headquarters and uncheck the background box, then if you restart our effect many times (by pressing the spacebar), then it seems the effect is either duplicated or something, but at some point it becomes very bright and if you then re-enable the background field, your preview screen will become very bright for a few seconds - I think this is the problem, I don’t know if Epic Games knows about this issue or not…
