I'm using Revit Architecture 2009 and are currenlty having difficulty trying to come up with sharper mirror reflections in my renders. Attached is an example of the distortion in the wall mirror. Since rendering this image I've tried experimenting with many render settings but still can't seem to get a better result. I've searched the forums but couldn't find any more information to help me on this topic. Any help would be greatly appreciated. Is it better to use glass or mirror material selection. Is chrome better than stainless steel etc. Any good info on how to best gain sharp reflections in mirrors would be useful information.

Did you look at the seetings of your mirror / glass. I have not experimented with these in 2009 but with accurender, you had to set in the materials propertiese how images mirrored and the quality of the mirror.

My materials have a material called 'mirror - vanity' that seems to reflect fine - see image.

So, is that the same material as in the first image?

I got my mirror from this site. I did a search using the term "mirror" and up came about five or six different types. I selected a couple and have been using them. All give the same result. The original material setting was mirror. Stainless steel, polished etc. I tried Chrome with no better result. I've also tried using glass with 100% reflectivity... again no better result. Is it possible for tim123 to post the mirror here so I can try it out in my model? My renderings have been of varying lengths, about six hours my longest.. still distorted. I've also played with the advance rendering settings, but still can't seem to make the reflection sharper. Maybe it has something to do with the exterior light coming into the room? Its obviously something fairly simple which I'm overlooking.

I created the mirror as a simple extrusion and created a material from the standard glass. I went to render appearance, replace and used the 'mirror vanity' material see image.

Thanks for that feedback. I setup my materials the same way and feel the results are slightly better. However, after playing around with mirrors in different locations with different results, I've come to the view that the distortion might be actually caused by the light refraction of the exterior light coming thru the big glass sliding windows at the rear of the render. I've also learnt in the past few days that setting up renders can be extremely complex! Varying levels of Artifical Lighting, exterior lighting, reflection, refraction, can change the outcome considerably. Its a very slow learning curve, trial and error.....does anyone know of any good learning material that explains all the in's and outs of setting up renders correctly with revit?

It would still seem that your material is not reflecting properly - I attach another image for comparison.

tim123 appears not to be using 2009. Stainless steel is a poor choice for mirrors. In 2009, under material settings, there are adjustments to reflectivity when viewed directly and obliquely. You should investigate those settings.

The first image that I posted shows that I am working in 2009 and the material from the 2009 library that I used to create it. Sorry - second image shows the material.

Thanks Tim. On your advice I had another go at solving this problem. The first attempts I was just changing the material to "Glass Mirror Vanity" of the mirror I had all ready being using - a download from RevitCity. This time around I created the mirror from scratch using the same method you used. Extrusion tool and then add material "Glass Mirror Vanity". The result is below. As you can see the distortion has now gone. However the mirror is much darker in appearance. Is a mirror made with a layer of chrome covered material - followed by a top layer of glass sheeting? I don't want to loose the colors in the reflection either.... trying to get a mirror just right is quite a job!
