Issue with Threshold option and missing Height option in Quixel Mixer 2020.1.6

Hello,

I am experiencing an issue with Quixel Mixer version 2020.1.6. In earlier versions of the software, there was an option to access the Height settings, but this option is missing in the current version. Additionally, when I try to use the Threshold option for height, the plane does not respond and does not move up or down as it did previously. In earlier versions, Threshold worked correctly, but in this version it does not produce the expected results.

Could someone from the Epic Games team please explain whether this change is related to an update or if it might be a bug? Is there any way to restore these features or resolve this issue?

I would be very grateful for your help.

Thank you in advance and best regards,
