Accidentally mirrored on an offset, too late to undo Recently I've been getting into 3D modelling in Blender.
I started to model a Glock-17, I blocked out the basic shape then extruded with a mirror.
The problem is when I mirrored it had an offset of 0.09 something and now since i have mirrored the object multiple other times since to duplicate surface detail to the other side and now there is so much extra geometry when I UV unwrap i don't know what to do to get rid of it, is there any external tools i can use or built in tools to fix this.
I'm trying to import this model into Unity eventually as a side not.
Start with that: Go into edit mode (vertex select) and select all, then in the menue on (most likely) the bottom left of the screen go to mesh --> vertices --> remove doubles and set the merge distance to 0.02
Then in the menue select --> select all by trade --> interior faces and delete them.
That should at least reduce the problem. From here on cleaning the rest by hand should be not too much work. To help with that you can use mesh analyses (in the properties panel).
