Very Noisy Render using Raytrace

Im Using the Movie render Queue in Sequencer to render an animation with raytracing.
Im using UE 4.27
GPU: RTX 2060

I have a DirectLight as the Sun, and a Skylight with Raytrace shadows. When I render the sequence I have grain all over the image

Are you changing any of the settings in the render queue? There are a couple of cmd lines that people use in their youtube tutorials to get high quality ray tracing and sampling. You should have a look at william faucher’s channel on there, he has an in depth video on the render queue.

increase the sampling count on the sun and the skylight. Try like 8.

Thanks, a lot better using the Console commands!

Also Im using: r.ScreenPercentage 200 to get better sampling

In the night version Im having a ton of fireflies on the leafs, for the moment using TAA is working better for me in the night scenes
