Hi,
does anyone managed to do a poisson blending shader for unity using GrabPass ?

Would you like to have only pure shader or full version with mouse and keyboard support (if you think about direct translation from Shader - Shadertoy BETA to unity).

I am too busy right now, but later I am going to help you.
Meanwhile, here you are my another example, where I translated Shadertoy’s shader to unity using GrabPass:

original source: https://www.shadertoy.com/view/llK3Dy

and Unity version Unity3D-CG-programming/rhodium.shader at master · przemyslawzaworski/Unity3D-CG-programming · GitHub

If you want to pass mouse coordinates to shader , you should read about sending data from C# scripts to them:
for instance, method Material.SetVector etc:

Hey man! thanks for the answer.
i don’t need the keyboard and mouse support, i actually forgot it was on the shader toy example.

i am looking to do seamless cloning of one texture on the grabpass texture
(grabpass <== blur * texture <== high pass filter)

like explained on those paper
