I have a transparent object, a sheet of water,
where use a sprite shader to clip the edges of the water sheet, creating a nice
animatable edge using animated mattes. Works fine, but I use an environment map
for reflection and refraction, and problem is can see the environment map
through the part of the water sheet which is supposed to be clipped by the matte
through the sprite node, which I don't want. Makes sense? I was looking at
the Ray-Type switch but it doesn't seem to provide what I need.
Does someone have a tip they can
share?
