Glass reflections when rendering in Alias

[dak76]

Hello,

A question for all out there, hope you can help.

I'm rendering a scene with glass materials in it (both clear and frosted). I want to get good reflections on the glass to add more realism to the scene but I'm struggling at the moment. I know that if you drop a abstract hdi image into the environment shader you do get this result... but it changes the colour of the background to match whatever the colour of the imported image is. I want to keep the background colour white.

Tried mapping a ball and image to the reflection setting on the actual glass shader but that only shows up if I turn the shader to almost a solid colour.

Any ideas or suggestions??
