Can I use modifiers to indirectly cause a 'loop in parents' error?

Yes, certain modifiers can indirectly lead to a 'loop in parents' error. For example, modifiers like 'Solidify' or 'Subdivision Surface' can distort the mesh's geometry, potentially causing vertices to overlap or become misaligned. Also, modifiers that create new vertices or edges can contribute to non-manifold geometry, ultimately leading to the error. It's important to inspect the geometry after applying modifiers and use the clean tools to fix any issues.
