Caching data in attributes not possible?

[jgjones]

I have a feeling the answer should be obvious, but do changes to ICE attributes not carry over to the next frame? I.e.: If I SetData in one frame, the attribute reverts back to its initial value for the next frame, yes?

For example:

Are you using a simulated ice tree or a normal ice tree?
An ice tree (not simulated) is calculated every frame, a simulated ice tree once it has an initial state always calculates from the previous frame.

In the example you posted an ice tree will set the data, a simulated ice tree will read it again and accumulate every time.

Ah ha! (I was using a normal ice tree.)

Many thanks! That info is probably in the docs somewhere, but I just missed it.
