Shrinkwrap and Concave surfaces

I have been playing with shrinkwrap because of all the drum beating on it.

However I get weird results on concave areas.

Are there any settings to correct this?

Miano, can you upload the file for someone to look at? What version are you using? —-Mark

Done.

I suspect this is a first for Rhino. Using Rhino to estimate how much paint is needed to paint a battleship

uncheck hole filling- and use these settings after closing up the top surfaces to make a more or less closed object before you shrinkwrap. -
