Newbie here, some artifacts on the images

I can confirm this bug as well, unfortunately i haven't found a solution. It does seem to be related to the scale of the scene though. What i mean by that is, when i hid the exterior of my scene the artifacts disappeared.

To try to track down what was causing it, I created a simple scene with room size box and added an opening for a window and placed a sphere inside. What i found was that changing the size of my scene along the x and/or y axis either making the box bigger or adding other objects to increase the overall bounding box of my scene in sketchup would make the artifact increase or decrease in strength.

I hope it gets sorted soon as it has the effect of making the materials look glossy and wrong.

arqcova Maybe the artefacts are caused by the low polygon quality and they are reflections at some bad mesh faces. But an other issue for me would be the visible noise. Are this screenshots of the Enscape window only or are this final renderings?

any recommendations?

could you create a simple example scene where this artifact apears or share your project with us so we could have a look?

Here is a simple scene that recreates the artifact.
