Height Map Problem behind Glass object.

[Anonymous]

I have a glass object with a height map plugged in displacement when I render the scene it's look fine but when I use another glass obj in front of it the render doesn't show the height data and the glass is rendered without it. What am I missing here?

When I render the light2_glass_main alone displacement is fine but when there is glass between it and camera the displacement isn't working right.

What you are seeing is not displacement. It is from the auto bump on the displacement. If you turn off auto-bump you will see that you really don't have much detail in the glass. Up your displacement and rerender with auto bump off until you get what you are looking for. You can bring your samples back down to a normal range.

I did the test with a checker map and it worked fine, but first I activated the subdivisions in "clark" with a value of 4.

Which texture map did you use for displacement map @Brian Foley ?

I just used cloth with stacked uvs.
