Change material or transparency?

Unity Engine
1

If either scenario is equally applicable, which would be the most sensible option?

  1. Change gameobject from material1 to material2. (no alpha necessary)
  2. Change alpha from 100% to 0%.

Would the answer depend on the number of gameobjects involved?

I’m not sure if any other details might be necessary.

Thanks.

Changing transparency from 100% to 0% makes no sense, changing material for the same purpose either.

If you want to hide object, just disable MeshRenderer.

obj.renderer.enabled = false;

I would still need collision, though. That wouldn’t be an issue? I feel a bit dumb now : /

Beauty of a component-driven engine like Unity: turning the Renderer component off has nothing to do with the other components (such as a Collider).

No need to feel dumb. Asking questions is part of learning!
