Rendering water in front of a background image
show user profile  br0t
Hey there,

so it seems I am a bit rusty in terms of rendering... I have a realflow mesh that I would like to render in a way as such the background image comes through but is distorted by the refractive material where the water mesh is. I thought this would be easy but it does not seem to work. The background image is used inside the environment map slot.



The material is fully reflective + refractive with fresnel checked. Why is it so dark...
Any help, what is the normal workflow to do this?

Note: Please herfst and LionDerp, hold yourself back :D

never get low & slow & out of ideas

Strange. Have you tested the transparency by putting a bright object behind it and rendering? The reason it's black could be because it's reflecting what's behind the camera (i.e. blackness).

Could you post a pic of your material setup?

Hm stupid me. Seems an environment map in the background is not enough and I need a real plane object. Used this script
to create one, now works fine

EDIT: might also have been the mappinf of the environment map, which was set to Screen...

Hey, I was right! Was just a stab in the dark. Anyway, your shot looks great now, with that water. Good job.
