  • I recommend you tone it down a little. The Lens Studio team is fairly small and not everyone in the community knows how to work with shaders. I for one have not coded WebGL shaders and don't know how to translate your shader code into material nodes.

    However, following the process in this tutorial I did create a sharpen material. You blur the image, subtract it from the original, add 0.5, and then overlay it on the original. The amount of sharpening is controlled by the blur amount. I have an example project here you can download.

    Note: The Pixel Size on my Gaussian Blur node is set to 0.001, 0.001 - it appears as 0, 0 in the screenshot below, but it should have a value. The bottom input on the Add node is neutral gray (128, 128, 128).

  • no it's me I'm sincerely sorry I'm French it's very difficult to find help.

    for the lens sharpen I would like to modify the source code of the shader or introduce our source code .

    the sharpen that you have it seems to me very well my when a value 4.00 it disappears the most contrast

  • It's a weakness of the technique. Instead of applying the sharpening as a post effect, you could try applying the material to a Screen Image and then scale up the Screen Image by a small amount (make sure you still keep it centered on the screen) to push the band outside of the screen area. If you have other items/effects in your scene you'd probably have to rearrange things, but it's something you could try.
