im trying to use a foreach to build one volume, but i dont know how to get it to use the results of the last iteration in the current one. i know how to do this in a solver over time, but i need to do this on every frame.

in the hip ive attached, im trying to get foreach1 to return only 1 volume, with all of the boxes sampled into it.

thanks

I did not get a change to look at your file, but I have attached an example that uses the volume that was the result of the previous iteration in the current one.

The trick is the “merge results” toggle on the foreach sop. With this on, each iteration gets the same original input, while turning this off provides a feedback loop, the result of the current interation is the input to the next.

Hope that helps.

yeah this helps a lot, thank you!
