Hello!There is a theme about rendering dynamic animation in V-Ray.As for the rendering time, of course, 30-40 minutes per frame, this is quite bad. Three-second animation will be rendered for three days😁However trivial it may seem, in fact, the solution lies not so much in the render settings, as in the financial possibilities. If to be more concert, then three.The first, uncompromising - to send animation to the render-farm, of course, its services are paid.The second, a compromise - to collect the render-farm itself. For example, we did so. We have six system blocks based on six-core processors at 3.2 GHz each core. And that:6 (processors) * 6 (cores in each) * 3.2 (GHz core) = 115 GHzThis mini render-farm has long since completely bought off itself. The operativity is the ultimate. No settings, queues, sendings and receiving results, all locally. This is its plus.However, compared to the real rendering of a farm, where a thousand, not GHz, can be provided, the speed of the rendering itself and the complexity of the rendered image, and hence its photorealism, are very limited. I can say that 100 GHz is extremely small for photorealistic animation and you have to speed up the rendering by unloading the scene, simplifying objects and lowering its settings, by itself, to the detriment of the quality of the resulting picture (video). And this is her compromise.The third, most not desirable, is to lower and simplify the animated version of the scene so as to shorten the render time to an acceptable one. What is an acceptable time, of course, everyone determines for himself, but in reasonable side-chapels, the rendering of one frame by the whole system should not take more than five minutes. Otherwise, the rendering of minute animation will last for a week.Some special settings or secret techniques that allow you to render animation of any quality on any computer - no 🙄 So you have to decide what compromise you are ready to make. Or pay for quality or lower it - saving money.
