Mirrored curve with Plane Curve modifier

I’d like use Curve modifier with a plane object. This is work with a simple curve. But if I use mirror in curve then the plane object (with curve modifier) follow the original curve. Original curve main the curve without mirroring.

So there are two ways I don’t use the mirroring in curve (but in this case i’m slower because I need to be setting the curve point twice)
Another ways to convert Curve into mesh object . but in this case I can’t use the curve modifier to my plane.
I think this is a bug: The curve modifier not seen the mirrored curve.

Any idea?

Be clear and show us what you have and what you want.

If your curve has a mirror modifier and the plane has a curve modifier to follow that curve, why not remove the mirror modifier from the curve and add it to the plane so follows the curve and that result is then mirrored. If the plane is not mirrored then there is clearly nothing available to follow the mirrored curve unless you mirror the plane as well


Very thanks, I try this.
