UE5.3.2 Niagara wont load any fire in simulation?

Hello!

I’ve recently ran into a very interesting issue with Unreal Engine 5 and am unsure of how to solve it or who to ask, so I am asking here.

I have a project in Unreal Engine 5.3.2 That absolutely refuses to load in any fire effect with Niagara. It will load the smoke, but will not load the fire portion. It does show fire in the preview tab but will not in the simulation.

I started a brand new simulation project, did not touch a single setting and simply enabled Niagara Fluids. After restarting I quickly copied the 3D gas Explosion template and loaded it into the world and the fire still doesn’t work. However, the smoke does.

Any help is much appreciated!

Just incase anyone comes here with the same issue, the fire does not show due to the sun sky.

For some reason the sun sky has a directional light which is set to something like 120000 lumens/intensity.

I fixed this issue by deleting both Geo reference boxes, then lowering the intensity to 10.
