I want to turn off "Push Transform to Houdini" on my HDA node in Unreal by default. I can't find it in the Type Properties window. How can I change the default to be unchecked?

Forget it. I accomplished the desired result in Houdini by using a transform node with

origin("","..","TX") origin("","..","TY") origin("","..","TZ")
origin("","..","RX") origin("","..","RY") origin("","..","RZ")
origin("","..","SX") origin("","..","SY") origin("","..","SZ")

in the channels and then ticking "Invert Transformation" down below.
