when i use quadremesh in the target edge length mode on the blue mesh(a product of shrinkwrap) it creates the red mesh which has a defect in its shape.
some observations:
the defect occurs only once in the product.
the defect occurs in one of the less complex parts of the shape
another similar but arguably more chalenging mesh was quadremeshed with the same settings with a satisfactory result.
when using the target quad count mode the defect does not occur. (a decent workaround is to use target edge length to find out how many faces you need and then use target quad count )
