Hi

Sorry for my post, I actually just found the solution

Apparently Sketchup was interpreting some of the flat areas as curved in my 3D model no matter what.

The irregularities were happening mostly on flat areas nearby circular volumes,
I divided these specific flat areas into smaller ones and apparently it resolved the problem !

(by dividing I mean I traced different lines in these areas, so instead of having one big flat areas, I have now plenty of smaller ones,
which doesnt appear in my rendering since I export everything with hidden edges)

Hi there

I'm experiencing problems with the fog effect when I export images/videos,
I'm using the fog option and it looks fine on Sketchup,
but when I export images/videos it creates stranges lines and irregularities:
flat surfaces appear as curved, and fog appear quite differently than on the model.
The phenomenon happens randomly on my model (cf.images)

I have switched to different versions of sketchup (6 and
I have tried to soften/smooth the edges of my model, create different groups,
separate, merge, recreate the elements subjects to these irregularities,
I have tried all the different formats of export, it always ends up with the same weird result.

I am running out of ideas...

any help would be much appreciated !!!
