VRay Test with Adaptive DMC samplar

For long time I’ve been using VRay without even fully understand how the image samplar works and how the changes of the options causes the result of an image. In order to get deeper understanding of VRay renderer, I played around with its options and settings, and the conclusion just blown me away. Basically, with some tweaks of the figures I can achieve much better result in the same amount of time.

VRay_Test_1 VRay_Test_1_Reflection VRay_Test_1_SampleRate

The above images extracted from VRay Frame Buffer with defult settings. I applied RGB, Reflection and Sample Rate render elements. Resolution 1024×768 and we can see the render time was 21.3 seconds.

VRay_Test_2 VRay_Test_2_Reflection VRay_Test_2_SampleRate

And here I did another rendering, which spent exactly the same amount of time to render – 21.3 seconds; the quality however was substantially higher than the previous one as we can see that much less noise been introduced in the image. No Indirect Illumination applied in both images.

For the 2nd rendering, Anti-aliasing filter been turned off, max subdivs 8, clr thresh 0.04, lighting (VRay plane light) subdivs and reflection on material subdivs 86 and left everything else the same.

Ummm this is interesting…
