Let say we got two object, I want to get the sum of the difference for calculating error between two meshes. As the sum of red and blue area following image showed:
Somehow the Boolean Modifier doesn't contain this option. I know it can be work by two ways:
Use Difference bool on each object with a duplicated one, and Union them.
Union both object first and subtract the intersect part.
But both of the method need a duplicated copy of mesh for reference, the second one even encounter the Overlapping issue.
Is there any easier way to get the XOR behavior in boolean modifier or similar function.
