Do you have more detailed steps to reproduce this? We can look into the issue if you share how to trigger it or log a ticket with our support team.

Thanks for the iteration variables in H22! That helped a lot. I partially solved the problem by using $F+@iter/@count in transform formulas. This is for a simple single formula animation. A slightly more complex option for a non-formula animation is to copy from the animation outside the block chf("...", $F+@iter/@count ) or cht(..) with $T+@iter/$FPS/10. But remember, this is for a single controlled parameter. If the layer is complex with several animated elements, this won't help. I was hoping for timeshift and timepack here, but frankly, I haven't been able to use them in the block yet. Either they don't work, or I don't understand the concept. As soon as I plug in the Time Pack cable, everything stops working.
Feeding a Time Pack cable should work if you set that input of the block to be Cable type. Inside the block, you can then use Cable Split or Cable Unpack to extract the frame of interest using the
@itervariable. The attached scene file shows this.Unfortunately, we can't yet use Time Shift to change when the input of a block should cook...
Edit: looks like Jeff and I made two versions of the same example for you! Renaming every wire to the same thing, then simply relying on the Index of Cable Unpack is a good way to generically loop over every field of a cable. The approach I'm using is stitching the name using a backticked expression, which is a little less elegant.
I'm curious. Why is rasterizegeo so slow? July 21, 2026, 8:58 a.m.

First of all, thanks for version 22! There are so many improvements!
But am I right in thinking that Rasterize still hasn't received a speed update? I tested it and see the same slow speed as in version 21. Has the issue been resolved?
We're witnessing the same memory leak under latest GPU drivers, so the interop feature is still disabled by default on Windows. The previous remedy with
HOUDINI_COP_RASTERIZE_INTEROPstill applies, and we have an active ticket to try fixing this problem fully. Thank you for your patience with this issue.
