Boolean union causes doubles?

Hey i just found this issue on Blender 2.82, 2.8 and 2.79

I duplicate a simple cube, try to boolean union them and they make a copy which is causein a weird glitch.

I hope somebody can reproduce it and hopefully find a solution :slight_smile:

Yeah, it’s not a bug, it’s totally normal : Boolean Union does create doubles, as original object still exists.

Here on your image the Boolean Modifier is done on the right cube. So the left cube exists twice : by itself, and also in the topology of the right cube.

Apply the modifier and move it, and you will understand :slight_smile:

See you :slight_smile: ++

Bool Tools addon. Just discovered it, and now booleans are fun. Gets rid of all the quirks that the modifier has. You should check it out.

lets call it feature :wink:

but by definition, boolean union works not like that. i will try the bool tool. there might be a reason why somebody made that addon.

thanks!

By what definition? It performs union, just like it should. If you need one-off boolean operations, just use them directly in edit mode. Modifiers don’t remove objects from the scene.

by my definition. it’s simply not working as i expect it :slight_smile:
