White dots while rendering using v ray.

I  already tried switching on sub pixel mapping   but I had no luck in resolving the issue.

Try change your vraylight material multiplier to 1.0, and check on the compensate Camera Exposure.

Yes, this seems to happen when your lights or self-illuminated objects are too bright for the sampler to resolve.

One way could be giving more samples, another way is using subpixel mapping, but you'll need to use the campling options for better results.

You could change your color mapping to Reinhard and reduce the burning to something like 0.4. this will make the whole image look a little washed out, but you can bring contrast back in the VRay frame buffer or in photoshop.

Hi,

In addition to the good advices mentioned above, i like to add one thing,

In Vray tab, Image Sampler(AntiAliasing) rollout, Image Filter group, choose

One of Vray's filters, like VrayLanczosFilter

You found the solution.Setting Vray light material to 1 and check on the compensate Camera Exposure solved the problem.
