Blured Photometric Lights In Reflections

[peterpiper]

Hi everybody.

So this is my setup:

 

I'm working with 3dsMax 2018 and render with mental ray.

 

Simple mesh with a ARCH&DESIGN mat on it.

Reflection Gloss: 1

IOR: 2

 

Lighting:

- 3 squared photometric Lights

- HDR map plugged into an environment Blur map

- The dimension of the HDR itself is 2000x1000

- Using the Logarithmic Exposure control

 

Normally I'm working with vray but now I'm trying to taker a closer look on mental ray.

As you can see that the area lights in the reflection are blurred and i can figure out

why?

The something happens when I'm using Area Lights instead.

 

Please let me know.
