Threejs WebGL vertex shader help

We need help with vertex shaders in our threejs app. We want to add the control segments "Blob Noise" and "Blob Surface noise" from [login to view URL] to our project: [login to view URL] The source code of the blobmixer website is on github: [login to view URL] We have already attempted to implement the vertex shader, but we have some difficulties. In this sandbox you can see the attempt. [login to view URL] The issues are: The slider "surface frequency" does not do the same as on the repo project The two PoleAmount Sliders dont work as expected. Deliverables Implement the functionality of the "Blob Noise" and "Blob Surface noise" sliders from [login to view URL] to our project: [login to view URL] You can use our implementation of the vertex shader: [login to view URL] and fix the discussed issues. As a result we want a codesandbox that is forked from ours, with the sliders working and the transition between slider settings to be the same as on the blobmixer site. (smooth transition between states).
