SPeckled effects from Vray light - plane type

[nigelwilliams]

Good morning
Please help me out with this one,

I am attempting to render some white concrete slabs, and find when I use the V ray light, type - plane, I get speckling on the surface, also the shadows are a bit weak this does not happen with with a standard directional light with a vray shadow map, what is most likely to be the cause of this

Is this a common thing with the v ray light

thanks
Nigel

Can you post an image?

Can you show an image of the problem area?

Those speckles are because your light subdivisions arent high enough - are they still on the default of 8? going to 12 or 16 will probably sort it out.
