Course: Hillside Sample Project: Unpacked

Hi there - I am using Hillside Sample as the basis of a private project to teach myself UE5 (first time in the editor since 2.11).

I am creating a visualisation of a spaceship landing near the apartments. It has Niagara Systems for its thrusters and also has emissive landing lights. I notice that I have to multiply the emissive factor by 1,000,000 in order for the emitters and materials to visibly glow in the sequence I am creating.

In the tute I followed to create the NS, the values are a lot lower (like 3.0)

Is there a specific setting in the levels (I am referring to _exterior here) that affects the apparent strength of emissive materials?

I also notice that the sclera of metahumans’ eyes get weird black artifacts as well - looks like the reflections are borked. Is this also related to the settings of the level(s)?

Thanks in advance for the assistance.
