Re: Sprites and environment maps refraction

No Alan I'm not using the rasterizer atm.

 

You can see the problem here:

What I think I would like is the Environment node to have Background Intensity split into refracted and non refracted rays - perhaps there is a way to do that in the Render Tree but I haven't found it yet.

If I had to take a guess it'd be that you're using the rasterizer. Soft hasn't updated their shaders to ensure they all work properly with the rasterizer.

I assume you mean you see what's behind an area which should be opaque right?

Cheers,

Alan.

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?
