Niagara particles dim and faceted with Movie Render Queue

Hello,

I have got a project which has got several Niagara sims. They render fine using the Legacy renderer.

However, as soon as I use Movie Render Queue, the particles come out dimmer, looking flat, and faceted.

I had initially added several console commands and thought they may be the reason but turning them off did not help.

I also tried setting the shutter speed to 3 in the Post-process volume and I am using 32 warmup frames.

I would very much appreciate your help here, as I am unable to render my project, and I would like to use the Queue because of console commands. Thanks!
