Particles Render Weird But Look Fine in Viewport

Hi There,
I am currently rendering shots of my animation and my particle effects look perfect in the viewport but when I render the flames for my torch in the background look red? No clue what’s happening.

I’ll attach a screenshot of my viewport and a render frame. (I’m aware the flame hasn’t fully started in the render but it is still red, and when it renders further the whole flame is red).

Does anyone have any ideas on how I can fix this? I’m pretty new to Unreal Engine and wouldn’t know where to start. I’m using UE4.


Here’s a better render example.
