Hi everybody!

So this is may setup:
-render is mental ray
-a studio setup which contains 3 photometric lights and simple mesh with a
a glossy arch& design material on it:

reflection gloss: 1.0
ior: 2

in the scene there is also an hdr witch has a dimension of 2000x1000. it is plugged into
a environment blur map.
for the overall exposure control i using the logarithmic control.

as you can see that the photometric light above is completely blurred.
i used work with vray but now i want to take a closer look on mental ray.

is there a way to get sharper light reflection?
