Why does this guys meshes look like this?

Why are his meshes red and the corners appear slightly rounded? Is this a add-on or a built in feature?

Hi @Lam0rak

Welcome to B.A!

It’s built in.
This is a matcap setting and cavity enabled, can be found in viewport shading.

Hope that helps.

Thanks! That’s exactly what I was looking for.
