My retopology sink into the reference model

[karanoshoujo2000]

After I retopologised the base model, I cloned the body part and tried to snap it to the cloth. But the retopology "sinks" into it, and as a result, many details are lost.

Is there a way to fix this?

This video might offer some good practices to use in such situations.

Thank you very much for this video, but what is the reason for that? This problem didn't exist when I retopped the body, so is there any specific way to construct the cloth to prevent this in future projects?

I suspect it may be due to the very thin nature of the object. In the toolbar (top of the UI), there is a list menu to the right of AUTO-SNAP that lets the user select what type of snapping they want to use. If you experience more of these snapping problems, try a different snapping mode and see if that works correctly. I would probably try the SNAP TO OUTER SURFACE. I find these kind of snapping issues to be very rare, actually, so hopefully this will be the last time you run into such a problem.

Hello!

Dont forget the Z-Bias offset in the Top Bar. It is a virtual offset between Retopo Mesh and Reference. In many cases It is normal that round surfaces stick through a polygon, because its flat. It can be fixed with baking inside and outside scan settings later. Just came up to my mind.

Hi!!

Sorry, I'm a little new at this, but what do you mean by " baking inside and outside scan settings later"?

Hello. No Problem! I meant this dialog, if you plan to 'bake' textures like color, normals, etc on your retopology. It allows you to artificially thicken the mesh, so that you don't have to worry about white spots on the texture afterwards. Just look how badly my mesh is sticking through, but the resulting paint mesh with normal map look totally fine.

Now with your thin cloth it is a bit special. It can also be that the retopo snaps to the wrong side. For that you could try

Increase the subdivisions on Sculpt Mesh, maybe try switching Voxel or Surface Mode, and use a smaller brush to get more snapping on the right side.

Or better, thicken the sculpt surface from the inside or even turn it to a solid if possible.

I think I would retopoligy only the outside and then use extrude shell to thicken the cloth.. 

Or use the Body for Retopoligy and extrude (for skinny cloth) from that. Lastly you can tweak the areas where the body sticks trough the cloth.

Hope this helps!
