How to fill holes in decimated geometry?

Support Modeling

Hey there,

I’m creating this retro lake scene and downloaded some rocks/boulders off sketchfab. They’re high poly so when I decimate the geometry I get all these little holes. I’ve never had this issue. I’m not sure if it’s because they’re glb files or what, but this is VERY annoying. Take a look:

How do I fill all these little holes???

thx!

My only guess is that highpoly model has unwelded vertices. Otherwise not sure what is going on.

You might try some remeshing ??
