Hi there. Not sure if this should go in this section or not, so sorry in advance.

I've been further extending my intersection shader to show sobel inside the sphere, and this is using the built-in SobelMain shader function provided by Amplify. I modified it to read screen color directly instead of having to sample a texture.


Problem is, it's checking color differences it seems, and that's causing the sobel effect to appear on shadows, and with any kind of significant color change on a texture (you can read the generator's High Voltage sign)

Is there a way I could stop this, like doing sobel based on depth?

I believe I could do it if I could access _CameraDepthNormalsTexture from ASE, but I'm not sure how to do that.
I'd like to sample the normals of all pixels on the screen, but I don't know how to change that.

Hello,

Thank you for reaching out to us, we would be happy to help.

Have you had the chance to try using a Global Variable? I attached a Shader Function to this thread that should provide a good starting point for your requirements; be sure to let us know if that is not the case.

I recommend checking the Edge Detect sample posted on the ASE Unity Forum for additional information.

Thanks!

All the best,
