Why does my 3D model disappear after applying remesh modifier? I want to apply the Remesh modifier to a 3D model but when doing so, the model disappears.

I have very limited experience using Blender and have been unable to find anyone describing a similar problem (except for 2D text).

A blender file which reproduces the problem: http://www.filedropper.com/remeshtest
Remesh modifier needs mesh with volume to work properly .
Flat meshes gives blank output as it cant compute the volume and mesh with holes produce a result with the holes filled.

also try instantMesh app github link
might give usable results

If you want to remesh flat/surface/text objects then use solidify before remesh then delete the extra thickness after applying the modifiers
