Differences in how DAZ handles overlapping planes VS Blender?

[Aaron J. Olson]

Hello, I am looking for some guidance on an issue I have encountered importing an environment. The environment https://www.daz3d.com/winterblack-halls

I load up the winterblack halls dbl preload scene. Do the usual dbz export. When I perform the import on the Blender side it is coming through like this

Where the model has overlapping floor planes and Blender does not know to handle it. Is this a bug or does DAZ just handle this situation differently than Blender?
Is there anything that can be done to fix or work around this issue?

Thank you!

That’s the viewport so some artifacts can be expected when geometries get close. Is the rendering fine ?

Alessandro, I hoped it would just be that, but in both renderers the artifacts remain (though they look different)

Update,
I manually adjusted each floor panel by small amounts (around .001 +-) and that has fixed things in the renders

So I will go with that. Not sure why/how DAZ gets away with weird overlapping geo like that. In this case the workaround isn’t terrible so I will close this issue as I am sure you have more important issues to look at, but if it comes up again, point them here.

Thanks!

closing as the workaround is pretty easy
