Hi, I made a HDA with a landscape input and a curve parameter. When I was editing the curve in UE4 viewport, each time I move the gizmo, the editor will freeze for a couple of seconds, which is very very inefficient(I already turned off Enable cooking on Parameter change).

By debugging, I found when editing the curve, the Houdini Engine will call the this function: UHoudiniAssetComponent::UploadChangedParameters, and therefore HoudiniAssetInput->UploadParameterValue() and HoudiniAssetParameter->UploadParameterValue() is called. I suppose this is the reason.

I want to know how can I do to prevent this calling and make the curve editing more smoothly? Thank you.
