How to make a mask that disables cloth physics on a defined area

Support Particles and Physics Simulations
1

it’s as the title says, i want to make a mask that disables the cloth physics on a specified area, i know that is related to geometry nodes but i can’t find any tutorial that explains that, to make an example i have a sphere that im inflating by tweaking the pressure settings on the cloth tab and i want a mask with a shape of a plane mesh that allows me to turn the object back to normal on the area of effect of the mask

i specifically want to obtain this effect but in this case it was made with shape keys https://x.com/HeavyWomanGuy/status/1775752125131141218, there’s more examples of different applications of that method on this guy’s account (i have to warn you that its full of weird stuff)

Cloth simulation creates a Cloth modifier.
You can make it shape keys, or you can fix it to a specific frame. :thinking:

I want to use the geometry nodes because it will save me the time of shaping everything all the time and I need to keep the cloth modifier on for my animation since the cloth physics will ignore the shape key

Hi,
you could create a Pin group and adjust that with Geometry nodes using the Store Named Attribute node:

Make sure that the Geometry nodes modifier comes before the Cloth modifier:

finally i start to see a path, the problem is that i have 0 experience with geometry nodes so i have no idea of what to do next

Maybe look up some tutorials on Youtube that cover the basics of Geometry Nodes?

This tutorial here might gives you an idea of how to achieve what you want to do:
