Also have this same question!

Am currently spawning blueprints with Houdini Engine and am looking for a way to set the values of the blueprint variables in Houdini.

Yes, looking forward to playing around with this in Unreal!

I am watching a tutorial on using Houdini with Unity, and I am trying to do the same thing in Unreal. The Unity plugin doesn't seem to have this delay which is why I thought something was wrong, but I guess it's just a difference between Unreal and Unity.

Thanks for the reply.

I'm having an issue in Unreal where if I click and drag a parameter for an asset, it will not update and cook until after I have let go of the mouse button.

All I have done is a simple test with a box a parameter to adjust the height of the box. If I click and drag, then release the mouse it will eventually cook and update after a few seconds (I also thought it would cook faster…) If I click and drag the parameter but never release the mouse, it never cooks and never updates.

I've found the option in the project settings “Cook Curves on Mouse Release”, but this toggle doesn't seem to change anything.

Any ideas anyone?

My Unreal Version: 4.18.3
My Houdini Indie Version: 16.5.378
