reflections from environment?

[Jonathan]

My poor laptop is struggling to render a scene with the environment (an hdri image) on. Left off the black background shows up in reflective materials. Is there a way (in mental ray) to only show reflections from the environment image?

Thanks

Try using the Environment/Background switcher...or with an Arch & Design material, you can just add the bitmap(reflection map) to the "Color at Max Distance" swatch in the 'Reflections' area in the Advanced Rendering Options rollout.
