I need to blur raytraced reflections.  Not sure how to go about it.  Diminishing the strength makes them faint, not blurry.  I want the environment reflected in a textured metal, just fuzzy.

Ideas?
Thanks.

This was always a problem with scanline, Raytrace just does not blur. You can fake it by applying a blurred environment map to your material, but the reflections won’t interact with scene objects. You could try the Reflect/Refract map which does allow blurring, but is less accurate than raytrace. You can try adding a very small noise bump to the material, though that may give grainy results.
This is easily done in mental ray with A&D materials, but I assume there is a specific reason why you cannot use mr in this project.

I forgot to mention......I am using MR for rendering.

Then use A&D materials. A Glossy Ref value any less than 1 will blur. 1 is sharp, the lower you go, the more blurred
To get smoother reflections of the environment faster, try this.

Thanks.  Will do Zap Brannigan.
