Problem with mia material x transparency

[how-cg]

Hi there!

I am trying to make an object A with the mia material x a see-through object with reflections, as there are other objects just right behind it. However when i render, the objects that are behind this object A become blurred.

I've tried grouping all the objects and scaling them up significantly, and it renders fine, whereby the objects behind the object A is crisp. So the problem lies with the scale/size of the material or whatever. And also I am thinking it may be because of the refraction index value or something, since tweaking that produces the most drastic change in results with everything else kept the same.

Will anybody be able to share their insights here? thank you very much

There's a bug in 2011 that causes unwanted blur on transparent objects that are in front of textured objects that use filters. http://bugs.thnkr.com/view.php?id=201

hi there thanks for the reply

I'm using maya 2009, and as it appears, the blurring of the objects behind will be gone if I scale up object A, meaning the blurring only happens within are particular size range.

If I scale up everything in the scene uniformly by say 10 times, the blurring doesn't happen, but if all the objects in the scene remains at scale x1 and below, the blur will be there. Not sure if this is a bug, but I'm leaning more towards certain settings in the mia material X that I am unfamiliar with and need to tweak before I get the desired result.
