Need help for Toggle "Remove BackFace" Parameter


Lampay

Recommended Posts

Hey Houdini wizards!

I'm currently working on an HDA (still in the process of building the parameter interface, so it's not fully finished yet). I’d like to know how I can use a toggle (on/off button) created in my HDA to control the Display > Optimization > Back Face parameter.

The goal is to be able to turn this parameter on and off directly from my HDA, without having to open the display settings each time.

I’ve tried solving this with ChatGPT, but the suggested solutions and Python scripts didn’t work for me.

I’m using Houdini version 20.5.332.

Thanks in advance for your help! Any suggestions, scripts, or guidance would be greatly appreciated.
