Why does the viewport display this effect differently than the particle editor?

On the left is the viewport, on the right the particle editor. Both are being viewed in lit mode. The only way I can make the scene viewport look like the particle editor is by setting the viewport mode to unlit. Is this intended?

Figured out what the difference was - unchecking the Separate Translucency under Show → Advanced in the viewport settings made the viewport look exactly like the particle editor.

Not sure why, but question answered at least.

Whatever you change in the viewport wont affect the packaged project so you should enable/disable separate translucency in the material of that particle effect.

It’s strange, I tried just disabling that in the material (and applied), but it didn’t fix the issue. Do I need to rebuild anything?

Edit: Ah nevermind, I was editing the wrong material. Works now!

Thanks
