I have an STL File that I know has inconsistent triangle windings. How do I entice ParaView to NOT show those triangles? It’s been a while but isn’t it something about backface culling or something like that?

I don’t know if it was described very well in the previous posts. The location of the backface controls is in the display part of the properties panel here:

BTW, if you are trying to find backface triangles instead of remove them, you can instead change the coloring of backfaces to make them easy to identify.

I found a little bit of instruction in one of ParaView’s tutorials: [11. Advanced: Tips & Tricks — ParaView Documentation 5.12.0 documentation](https://docs.paraview.org/en/latest/Tutorials/ClassroomTutorials/advancedTipsAndTricks.html#backface-styling)
