Ok, so the ray depth solved the problem with the wine glass and transparency. However, I am still having problems seeing my SkyShader through the windows.

Here's a screenshot with the window planes switched off. The SkyShader is right there.



However as soon as I reactivate the planes with the glass material - it looks like this. And yes I have made sure to uncheck the Opaque option for the mesh - the light is still shining through I just can't actually see the shader outside.


Is there a setting I have to adjust to allow seeing the SkyShader through objects?

Again thanks.
