I have an HDA for a procedural building that takes a cube as an input for the size of the building.
When I update the scale of the cube, the HDA re-generates the building, as expected.
My idea is increase the scale of the cube over the course of a few seconds in the UE5 Level Sequencer, and have the HDA re-cook every frame so that when rendered out, the building procedurally grows every frame.
Unfortunately, the HDA only seems to cook on the first frame and does not update over the time of the render.
Of course this wouldn't make sense to have running in-game, but It'd make for an interesting render.
How can I force a re-cook of the HDA every frame? Thanks in advance
Here is what the building should look like at the beginning of the render
Here is what it should look like a few seconds later, as the input cube scales up
Here is my current timeline
