Instance animation start frame offset

[Ryuji]

Hi, 

I've been playing around with instancing and I didn't manage to change the animation start frame on a per instance basis. 

For example, if I instantiate a cube with an animation (keyframes or bgeo sequence) onto points, all the instances play the animation the same way. (See file below)

How can I change the animation start frame on a per instance basis to randomize things a bit (be it keyframes or bgeo cache)? 

Thank you in advance.

bump would also be intersted in seeing a way to do this!

Perhaps use instancepoint()? http://www.sidefx.com/index.php?option=com_content&task=view&id=1050&Itemid=216

Correct me if I'm wrong, but as I know, the only way to do this is using delay load procedural in conjunction with instancing, i.e. you have to bake your animation to bgeo sequence and then read it via delayed load procedural. Then you are able  to override path to geometry on per particle basis. Check local overrides settings in Material SOP node.

Here is a small example of this technique. render the sequence to see the effect

Hey Gosch,

 

Thank you very much for your answer. I'll take a look at your file.

For simple animation, I used a vop sop to animate my instances, and used ptnum to offset it on a per instance basis.
