Hi Guys,
Yup - my first newbish question
So far things are going fairly smoothly learning this new fangled VRay renderer, but there are a few problems that I was hoping you folks could help me out with.
My first problem is that I am getting alot of blotching and artifacts when I use displacement mapping in my scene. For this render I used Irradiance Map / Lightmap. I tried using the "high quality" preset and the problem becomes more pronounced. After reading through the manual, it looked like it was the sort of thing that increasing the subdivision and "interpolation samples" might correct the problem, but even with very high values such as 16 subdivision / 30 interpolation the problem still exists, albeit much less pronounced. The downside of doing this though is that the rest of the shadows in the scene become blurred.
Just wondering how you guys would go about handling this. I also tried changing the light cache Subdivisions and sample size but these don't seem to make much of a difference at all.
Thanks in advance for any info - I think once I get this renderer all figured out I am REAALLY going to like it.
Here's a link to a render of the scene in question.. You can see the blotchy portions on my displacement mapped siding.
