Wireframe updating bug

[DoC-Noah]

Hello, I'm trying to remove triangles from a mesh and view its wireframe, but the wireframe doesn't update when triangles are updated.

Here is a sandbox showing the issue.

Edit:
Solution found! Thank you drcmda and bananu7!

i don't think this is related to react. i don't know how wireframe is implemented but it's probably something that isn't updated when you change buffer attributes.

You were right! The version wasn't updating.

I think enabling wireframe might actually override your modified index buffer.

See here: https://github.com/mrdoob/three.js/blob/fadb6ab1cfcf917e8287e2cca6292aae6ef15793/src/renderers/webgl/WebGLGeometries.js#L155

It's most probably not an R3F issue, it's a three issue.

Thank you for the link to that code! The reason why the indices weren't updating was because I was making a new indices buffer attribute which would always start with a version number of 0, so the code you linked to wouldn't trigger the update since the version number wasn't incrementing. When I started incrementing the version number by finding what it was on the last indices buffer attribute, it started working! Thank you again!
