It has been over 7 months since the release of earlier Service Pack and we will be getting another free upgrade in Q1 of 2017. It’s now in public Beta stage. In this post I point out and review newest features and improvements of upcoming V-Ray RT GPU 3.5. I will focus only on GPU side of the engine as I think it deserves way more exposure than it gets. While it may seem like a small addition to V-Ray CPU (Adv) it’s in fact full-blown production rendering engine that paves the way for better and faster rendering workflow.
Over the course of last months I’ve been crazy enough to keep installing latest Nightly builds of V-Ray RT GPU on regular basis and abusing the hell out of it. As I’m sharing all the my testing data, bug reports and improvements ideas with Chaos Group team I also feel partly responsible for its current shape.
I. Adaptive Lights
First time I’ve got familiar with the concept of better multi-light rendering back in July 2016. At the time I was pointing out poor performance of many lights rendering and I got promised that it will get faster. Adaptive Lights took few months to develop and from what I know it’s quite innovative approach that yields very good results. I’m super happy about that feature as V-Ray RT 3.4 wasn’t effective with many lights and this improvement helps a lot. It did turn out better than expected as it not only made rendering faster for RT GPU, but also for V-Ray CPU Adv.
Pros:
Cons:
Usage:
Based on my tests so far it always performs better with Adaptive Lights turned on. It’s also turned on by default so there is no reason to switch it on when you use “fresh” settings. In case you need to change it for some reason. In 3ds Max you can use it from Production Renderer settings under Global Switches rollout. You may to change settings type “Advanced” or “Expert” if it’s invisible.
II. Aerial Perspective
Pros:
Cons:
Usage:
Example of using aerial perspective for underwater shot. Effect setup starts at 2:50.
III. Procedural Shading
I just love procedural shading, but I’ve missed some things for procedural bump. Around 2 Months ago I compiled a list of things that didn’t work as expected and sent it to Chaos Group, after few weeks most of the issues were gone and I’ve produced this series of cool looking shaders:
Pros:
Cons:
Usage:
