I don’t have acccess to commercial cloud, but will add 1TB swap and see if this replicates.

Actually I tried with the new surface nets/smoothing option enabled, and everything worked fine, up to a point. Model is supposedly generated and saved into the scene, I can look up it is properties. It is over 600M polygons.

But no model is being displayed in 3D viewer. There is an error about display properties:

Right now I am saving it as PLY, it has been over 30GB and still going on.

@Tyler so things are working, but the resultant model will be so big am not sure what you can do with it.

Ill try that, I assumed the new surface nets option is less accurate though?

I have not noticed any issues with it to make me thing it is any less accurate.

ill make a comparison then with the halved part too

tried with the surface nets option (not smoothing) and same error.
