Solidify Modifier Creating Weird Edges

Tried using the Solidify modifier on my model and it’s giving me these weird edges. Anyone know what’s going on?

Before Solidify


After Solidify


try applying scale first ( ctrl A )

…now I’m embarrassed.

Hey don’t be, I think we’ve all been there more than once! :wink:

In addition, maybe it was wanted but you have double edges. ( can see it by the center point of face ). If the vertices are one over the other this can be troublesome in some cases. ( extrude etc )
