I will need to have in my animation an mesh object suddenly to appear from nowhere, also a light (it will be electric bulb)… is this possible to do simple or I need kind of workaround…
What falls on my mind is to have that bulb and light in a layer not included in render, and then include it somehow dynamically in the render, and turn it off when needs to dissapear, but is that possible ?
Or is there another way ?
Two other ways to do it (eg. if you wanted them to fade in or fade out): animate the alpha value of the materials, or use a “time” node in a composite that has the background on one render layer and the objects on another, combined using an alpha over node. I don’t think that’s what you want to do, though, so I won’t explain them in more detail.
