I posted this as a question on the Answer Hub but it may be more complex of a discussion than that’s suited for.
I’m wanting to create a material like the one used in the “Showdown” demo shop windows but with an added refraction effect on the “window” that distorts the parallax background (like water droplets).
Here’s a short video of the Showdown VR Demo parallax material I’m talking about.
The “Showdown” demo uses Bump Offset to shift the texture(s) as your perspective changes and I’ve gotten that part to work just fine. However, I’m not sure what to do to the material to have droplets or ridged glass that further distorted the already distorted parallax background texture.
Here’s some example images showing the effect I’m after:
Or like the window is made out of a ridged glass defined by a normal map or height map.
My guess is perhaps another bump offset node at plane zero with a height-map defining the glass distortion that further modifies the uvs coming out of the parallax bump offset node?
