How do you animate disappearing and reappearing objects?

areg5

I use animate2 and Daz Studio. Is there a way to animate the appearance or disappearance of objects? For example, having clothing fade in or vanish?

Not simply - you could use a Shader Mixer shader and link the opacity to the time/frame number but that might be a lot of work if the item uses a shader other than the default.

What I do to simulate the appearance/disappearance of objects in my scenes is to set the Y coord off-screen (under the ground or really high).

Keyframe one frame before you want the object to disappear, then on the next frame set the Y coordinate higher or lower so it's out of your render/viewport region.

This tactic won't work (obviously) for fading an object. You could use multiple objects of the same type and change the opacity of each to simulate the fade in/fade out. This could get resource intensive, however.

To be honest, I tell you what is the quickest way to do that: use adobe after effects.
Make a first render with clothes, a second render exactly the same but without . Then you put both in after effects , and animate a mask, or a transition between two layers (it's very basic, easy to do)
I m making medical animations, so at first I show a clothed character, then the "inside", clothes/ skin are disappearing, using this way.

Post work does have the advantage that you won't have a partially visible back or interior surface during the fade.

Ok...I have both renders. I put them in after effects. I am very new to this program. How do I "animate a mask or transition" between these pics?

I don't know in Studio but in Carrara, it is very easy!
You create a keyframe in the “visible” line and a little further, a keyframe while making the object invisible.
Here a test that I carried out for my film and the initial character disappears as I have just explained it to you (the particles, it is other thing…).

In AE, you place the first footage at the top layer and the second exactly down the first.
You deploy the properties of the top layer and at the place which you want, you create a keyframe for the visivility at 100% and a little further another with the visibility with 0%.
Attention, small “chronometer” in the left side must be selected to be able to animate this parameter.
You can also create a layout as in Photoshop and animate the various points.
For a simple crossfading, you would have easier in Premiere or a other soft, its very basic.

Here is a pic you have to animate the opacity of upper layer

And the values: from 0% to 100%

If you want to make something more complex, you can create a mask .You can animate the points of this mask, so the layer will appear parts by parts (more control)

Good tip on Carrara, I'll have to try that. My first instinct is the "After Effects" approach, i.e. render the whole thing with and without whatever is supposed to disappear, then layer the two video clips and adjust the "opacity" over time. As I've mentioned elsewhere, I have After Effects but its very expensive, many of the consumer priced video editors do this also (mine is a version of Magix' "Movie Edit Pro").

Thanks guys! That worked out great!

This is true - Carrara can do so many things -
Dudu's video was created for the "Shatter and Disappear " exercise over on CarraraTors - the community site dedicated to Animation and Carrara. We endeavour to create using only Carrara without other software or post effects
If you haven't checked it out we would love to have you join in and share your knowledge and experience

A bit late to the party but if you have two clips (with and without) and a simple multi line video editor just synchronise the two tracks on separate lines and cross fade.

Keep it simple ;-)

Since Studio apearently can't animate visibility, instead of going through that in AE, you can make the object or figure disapear by moving it out of the scene. Animate its position to a place out of view of the camera.  (even simpler workaround)

The easiest way in DS is to to toggle the scale to 0% to make an object invisible.  You can keyframe the scale property  so it works well in animations.  DS does need a lot of work in it's animation capabilities, but it doesn't seem a priority for DAZ3d.

There is a visibility on/off aniblock for animate 2.

animated textures by mcasual

i used it succesfull for animating opacity

Agreed  I  use the vanishing or disappearing ani block works great  they can be used for clothing body parts and on props and on hair as well. if the item is on the time line then you can use the invisible aniblock  if you just want a fade effect then slow down the frame rate of the invisible ani block. and cut it off at the point you want the fade to stop at.. simple and yet works wonderfully

may you please tell me where is this to find ?

They originally came as default aniblocks with Daz3 under "Animate plus folder" in the viability sub-folder.

that is how I got mine anyway.  see capture
