White spots in reflection with vray IES lights

[Equanima]

Hi,

How to avoid the white spots in the reflection materials when the vray IES lights are used? Thanks.

The black edges are caused by sharpening AA filters. Briht spot artifacts can be removed by ticking "clamp output" and "subpixel mapping"

Thank you, Thorsten.
I ticked "clamp outpout" and "subpixel mapping" in the "color mapping" panel.
The black edge is gone but the white spots are still there.
Usually I use photometric lights and I untick " specular " in the "advanced effects" panel to remove the white spots.
Any ideas?
