Pixyz Studio includes a function helping removing Z-fighting (surfaces overlapping).

NOTE                Find here information about Reasons for Z-fighting

The Remove Z-fighting function is a semi-automatic process, that requires to select meshes that show Z-fighting first, before running the function on the selection to remove this annoying visual artifact.

Selected surfaces are automatically and slightly shrinked (mesh vertices are negatively offset by a value calculated automatically), to remove the overlapping.

How To

Follow these steps:

1. Select one of the meshes whose surfaces are overlapping with other meshes (the one that will be shrunk, thus disappearing behind the other overlapping meshes)
2. From the Mesh Menu, choose Remove Z-fighting

And that's it!

TIP        Add a shortcut to this function to quickly remove all overlapping one after the other.
