Hi. I am very new to Houdini and I could not figure out how can I use mountain node in a more controlled manner. Basically, I have a cigarette. I want it to burn it out from top to bottom over the time, hence displacement. For instance, material_fracture can be controlled by animated volume box. Is there anything similar what works for displacement? I would really appreciate any help. Thank you.

on Mountain SOP enable Blend and change dropdown from Constant to Use Attribute
then specify float attribute that contains your animated mask

Fantastic! Thank you so much!
