How to mirror an object AFTER it's made?

[shoguntaijitu]

That's it. Mirroring before is easy, but after seems to not be an option. Hope it is though...

as far as i know, there is no way to do this. Pretty big oversight, I wish they would add it in.

Yes, please.

Why not export only 180 degrees or export all and slice in half. This latter method would give the advantage that you could "simulate" a full planet by "switching sides". Or any level in between.

Then import tool into ZBrush, ZBrushCore or Blender, etc. Press 'X' to enable mirror mode before you draw using your imported tool. I've not tried it, but should work ZBrush and in Blender or anything that can mirror, right?? Reapply maps if/as needed. (They'll still "fit".)

Bottom line, you mirror in your 3D software, not GD.

You could also mirror in Unity and/or Unreal. Even if with a manually "copy and rotate 180".

It depends on what you want to do with it from there.

Best wishes.
