Fresnel Shader or similar effect

Apologies for replying to you directly, but I think your code might be exactly what I’m trying to achieve.

I’m trying to achieve a look like the third bubble from this picture, transparent material with white fresnel basicaly. I actually found a few routes to apply a shader using ShaderFrog which is another tool that has been written to try to combine shaders from Shadertoy into ThreeJS, this is the closest one that I’ve found and I’ve got it working, but crucially it’s breaking my animations, and that seems like it’s a thing with some shaders and skinned animations.

I found these replies of yours, and I can see the preview for the Codepen, but when I actually open them, none of them are working with Fresnel effect, and I just have 0 idea about how shaders work to understand what I’m doing to try to fix them.

Is there any chance you can help me?
