The idea is that storing an incoming animated abc's transformation coordinates and read it back in houdini without the need to load every frame from disk. Any idea? thx

Hi,

Maybe you can use chop to store the position and then read it back. But the chop itself would of course read the datas from the abc, so you might have to cache your channel. I don't know if it would really be faster.

What do you want to use that for ? Do you have an example or hip ?

CHOPs should be fast as caching the channels in CHOPs will be able to store the whole animation, so then once channel cache is read to memory, it can play from there

you can also represent your motion paths as geometry trail with instancing attributes, look inside of Crag Test Geo to see how it's using that technique to animate the pieces
