I'm a newcomer to Blender and have created a scene in which I want to animate the disappearance of an object. I don't know if this is the 'right' way to do this, but I managed to get the desired effect by having a big block move over the object to be disappeared, and I added a boolean Difference modifier to the object to be disappeared.
This gets me the effect that I want, but I haven't been able to get my big block 100% transparent. It's almost, but not quite, entirely unlike a solid object, but it still casts a shadow and appears to have other visual effects on the animation that I don't fully understand.
Can anyone hand-hold me through creating an absolutely invisible material for my big block, or teach me the 'correct' way to accomplish my goals?
