Faking the presence of object in refraction

Recommended Posts

HI guys! Do you have any idea if is possible to fake the presence of an object in the refraction inside of a shader?

 

I have a piece of glass and I would like to make it refract a grid (or better a texture) as it is below. The point of this is that I am trying to create a shader that always refract the user specified texture without the need from the artist to manually create a grid, set the uvs, position it to a certain height and apply a material with a texture. Ideally the result should be the same between the two options, without  a big difference.

Sounds like a Room / Window / Parallax shader ; Sorry I couldn't find it for Houdini

That's what I was searching for, thanks. Doesn't matter if it's not for Houdini :) There is the paper so probably I can adapt it somehow for the refraction.
