TGI3D has a great downsample tool that respects vert location and can smooth a mesh afterwards for optimal results.

I can not believe ๐Ÿ˜ฎ , just uninstall that plugin, along with others who did not use both.
To others, I never understood how to use it well, to function in the plugin you mean?

The other thing I can think of is some plugin or method of doing something like the intersection option. ๐Ÿ˜’
Something?
