VrayLightMTL causing noise

[mjaco]

Hi

I am trying to make cove lighting, the way I did it was I applied a Light MTL to a renderable spline set the amount to 10, But as you can see in images below that it gives me this unwanted noise I cannot figure out why this is happening?

Please give me some advice; I am new to vray, and have a deadline approaching

Thanks


I am using vray 1.5 with viz2006
My settings are
IR map set to high- LC Subdivs 1000- Fixed image sampler subdivs 4





With the cove lighting object

Without the cove lighting object

You should increase the hemispheric subdivs for the irradiance map, or alternatively, use VRayLight's instead of the VRayLightMtl.

Best regards,

I tried that already, I was at 30 and pushed it to 40, should i try 50, wouldn’t that give me huge render times?

I guess I will rather use vray lights,

Thanks
