Face all Faces Out?

Matte

Hi All,
Is there a way to take a model with thousands of triangles.... 1/2 are facing "out" (White) and 1/2 are facing "In" (Backside Blue). Instead of spending a week reversing every face one by one... Is there a plugin that will make them all face the same way? Even if they all become "Backwards" (Blue), I can then just pick all and do a reverse face.
Thanks all for your help.

What happens if you right click on a correctly oriented face and choose Orient Faces?

If Orient Faces does not work, then you can try FredoTools::AutoReverseFaces.
