Hi, just stumbled on this as well. Old thread but can be good to write anyways.

Just make sure that the attribute "pscale" exists on the points of the incoming curve. You do not need to enter anything in the width parameter of the sweep node. I guess pscale works as a multiplier of the width parm value.

Hi!

In Houdini I have simulated and exported a VDB sequence that I am importing into Unreal as an animated SVT.
I am having some issues with aligning the Heterogeneous Volume actor so that it matches the transform in Houdini.

What I have done so far to get the placement of a Static SVT to align is the following:

Location x = Houdini center x * 100 (The center of the Houdini sim)
Location y = Houdini center z * 100
Location z = Houdini center y * 100

rotation x = 90
rotation Y = 0
rotation Z = 0

scale x = 100 * Houdini sim division size (if the sim div size is 0.01 that would be a scale of 1.0)
scale Y = - 100 * Houdini sim division size
scale Z = 100 * Houdini sim division size

If the SVT is animating I can not get the Location to align. I have tried using the first frame center, the last frame center, the "combined center" of all frames of the sim... but I have not been able to align it yet.

Does any one know the correct way to align an animated SVT in UE?

Thanks!

Thank you for your quick reply!
Really interesting to hear about the improvements in H20.
