Quote - No, the other way would be to make 100% transparent all materials for the object, and make them 0% transparent when you want the object to be seen again. Then it depends on what you want if you want a quick change between visibility states, use 2 keyframes between states, or if you want a transition between states, let about 12 seconds between keyframes and say yes when Vue asks you if you want the change of matrials to be animated. Vue will then create a sort of morphing from visible to invisible during the time you left between keyframes. 12 seconds is good for a nice effect.

 

Ok I will give it a go...
