Path Tracer lines on surfaces

Anyone else having these lines on the walls show up when Path Tracer is turned on? I tried changing the bump of the materials, which did nothing. Then I changed the near clip settings, which only changed the size of the gap between the lines. The only thing that gets rid of them is turning on depth of field, but I shouldn't have to have that on.

The project is being imported from Sketchup Pro 2022 into Twin Motion 2023.

Yes - similar problems here - possibly due to the cad model origin not being close to x,y,z = 0,0,0. Also, in my case - the model started life in an earlier version of TM.

Your depth-of-field solution works for me.

I am also having this same issue. I have modeled a memorial museum for a studio project and whenever I activate the path tracer these lines show up. My model is far from the origin point where the Revit project started from. I will try this method and follow up.

I have also noticed that adjusting the fireflies also reduces the number of lines shown, but tampers the view for something not entirely desired.

yes, i have got the same issue but don't know how to solve it at all...P.S the project is imported from archicad 25 via direct link
