Why are parts of my exported image smudged?

Development Getting Started & Setup
,
1

I am new to Twinmotion so I'm hoping this is an easy fix. I'm currently using the trial version (testing out for my work; we use Lumion now). DOF and Smog are off. Lens Flare is 0%. Samples per Pixel = 256, Denoiser=On, Aliasing=3.0.

I'm about to pull my hair out trying to figure this out so any help would be greatly appreciated. I have attached the image as well. The whole image is just covered in these "smudges".

Hello ,

Thank you for posting in the community and sorry to hear about the troubles.

  1. There could be a setting effecting this and maybe turning off Auto/Exposure and setting the exposure manually could help.
  2. You can also try rendering the same image with the lights turned off to see if the issue is coming from the light source.
  3. Does it look the same in the viewport and exported, is motion blur on in the more export settings, maybe try turning it off?

Here is the overview tutorial on Path Tracer that could help: https://www.youtube.com/watch?v=XlFQ2HbiGvY

You can also look at the Lakehouse Demo scene and look at the settings for the interior renderings.
