When I use burn in lwf and reinhard color mapping I got only two specles
This is the first time I see something like this. Is it possible that it has something to do with only using HDRI as light and nothing more in the scene ?
If your using the Adaptive DMC Sampler, up the Max Subdivs to something like 24 and Clr thresh to something like 0.002. I had the same problem and I fixed it by doing that. See stage 5 http://www.mintviz.com/blog/vray-interior-rendering-workflow/
Hmmm..Well it worked for the spot issues that we had on a couple jobs. We found out that when we used a vray sun we would get these spots…Sometimes by turning off visible to reflections on the light it would get rid of them. But i wouldn’t use the universal settings. Here is a good blog about how to set things up… http://www.davidfleet.com/tutorials/linear-workflow
