  1. What is the reason the same frame looks so different?
  2. How can I make render looks exactly viewport frame?

I’m using MPC in Sequencer:

My suggestion was that MPC doesn’t recognized in render, but actually if I just remove MPC and render scene as it is – there is the same big difference between viewport and render.

I also created new clean level and added Ultra Dynamic Sky only, set clouds speed to 0, but again: viewport looks dramatically different from render.

Did you find a fix? This plugin is completely unusable if this is the case still.

I have the same issue, tried different cloud settings, setting cloud speed to 0, etc but the movie render looks completely different, even as drastic as clouds in viewport and clean sky in render

I got the solution from the dev:)

Verified worked for me:

“ Make sure that you have either disabled Randomize Cloud Formation on Run, or you’ve set Project Mode to “Cinematic/Offline” which disables the same behavior.

Also make certain there are no other volumetric cloud components in the level or other UDS actors which could be conflicting at runtime.
