Geometry Node Tension Maps

[Amethyspian]

I’m currently researching Tension Map creation with Geometry Nodes, and I’ve hit a frustrating roadblock.

Below is my setup.

(The lower half contains the Geometry Node setup. The upper leftmost region contains the Shader Node setup. And the Render is the object affected by the setup.)

This works well as-is, and isn’t the part I need help with (Though, quality of life suggestions are welcome). I have an issue regarding one vital step. I am told I need to duplicate the mesh, and hide it, so I get an undeformed version to use as the basis. Even the Blender Developers have cited this method- and may have created it. Though, I noticed people claim to use the Rest Pose Attribute as a stand-in.

How would I go about implementing this? I have only seen this method brought up in comments under videos on YouTube, but an actual tutorial has never been made on it- to my knowledge.

Any help is welcome!

Here, tick this then use rest_position as a named attribute to access.

Hope that Helps

Oh wow, thank you! That saved me more hours of scrolling I’m surprised it worked so well.

This is a common issue, so I thought I’d share the final result for others!
