Hi, I am new to image sampler and I am experiencing issues whereby the sampling of the image i used appears to be inaccurate. I could not understand what is the cause of the error I have tried to simplify my script as much as possible. I would appreciate if somebody can help me with this. Thank You.

As you can see, that’s because you provided the wrong X & Y domain of Image Sampler. You don’t have to change the default domain(which is 0 to 1) if you reparameterize the surface input.
