Shadow flickering

[michal.p]

Hi!

With my model growing bigger and bigger I started experiencing crazy and nasty shadow flickering.
It’s understandable with larger models (and mine was so) due to limited Z-buffer accuracy (precision? I never know the difference). BUT. I removed all large geometry, then purged unused stuff so my model extents are like 2x2 km now. This doesn’t sound like super-large. I used to have larger models with no issues.
I have no advanced camera in my model.
If I copy stuff to new model, it’s fine - shadows are cast neatly again. But I’d rather stay with my current model (cuz I can’t copy scenes).

I can see the problem was also described there:

Fog and shadow problem

With activated fog and shadows in my.sketchup, I get a flickering like z-fighting… [image]

But I don’t think there was a solution found till now. Cotty had this problem even with super-simple model. Plus I use SU 2018 Pro for desktop, not web.

Thanks! This can help but do you know if it’s possible to fix this model?

Ohmygosh, I know now.
I used this extension: SketchUp Plugins | PluginStore | SketchUcation
to force near clipping distance and I entered too small value which caused severe display issues.
Excellent tool but gotta use it carefully!
