I've figured out a way to automate the metasurface using external hardware, but is there a way to do it internally in mulch? Like meta-automation? Sorry if this is a noob question, but I took a quick browse through the forums and didn't see anything.
View > Parameter Control
Metasurface > Interpolate_X
Check the "Automate" checkbox. Same for Metasurface > Interpolate_Y
Is that what you were after?
