Buckets get stuck for hours Konstantin in Windows, they take so much time to render that Window, probably for refraction of a window, two sided material for the garden, something weird happen when You render a very heavy complex interiors, thats why i switched to progresive render. When i render an exterior scene vray gpu works very Nice and very stable, but when i render a Big interior scene and i have a Lot of Windows with gardens, lights, shadows, then vray gpu suffers. Well not everything is bad news, some things work right now with vray 5.1 update 1.5 very Nice for example not vram problems, i can render almost every heavy scene with update 1.5 the 2 gpus share very Nice the vram pool (nvlink works Nice), before that for example with vray 5 i had a Lot of vram problems, but update 5.1 hotfix 1.5 seems very stable and this is very important too. We will do our best to resolve this issue once we can reliably reproduce it.

Is there any other V5 specific feature that you've enabled after upgrading.

Do you have the global Contours enabled? This is an effect that can slow down the overall rendering even if it's only visible on a couple of scene objects.

Which V-Ray 5 version are you using to test this (or is it the same with all V5 builds)?.Which stage of rendering is slower? Is it the model loading time (before the rendering starts) or the render process itself? If it is the rendering stage, is the Light Cache prepass taking longer or the final frame evaluation?.It is very important that you share the 3.6 or Next scene before it has been upgraded to V-Ray 5. To share the models you can use any free file transfer service you like and then shade the link to the file as a direct message.Īnother option is to attach the models to an issue in our support system. The more projects we have for testing the better.

However, there might be something we've missed.Ĭan you guys share any example projects that show this difference? We haven't made any significant performance related change in V-Ray 5. I'm very surprised to hear this actually.
