Same here in v7. Though thats interenting that it happens only on your file i just put sth else to try and don’t get flipped normals.

I also noticed that you have some hisory on object maybe this is the reason ? Don’t know just guessing.

Hello - got that, thanks.

Hi @KeithR,

How did you create the mirrored instance reference, and how are you determining that the mirrored instance reference’s definition geometry has it’s mesh normals inverted?

Hey @KeithR, long time.

I thought this was fixed, but it’s just weirder than I thought.
