vray fly through please any help/advice

[3rddimension]

hello

I need to render 2 internal animations maxium 800 frames and all in the same room.I am an intermideate user but having said that I have never rendered an interior fly through before with light cache. 99% of the scene, etc is done. my main problem is getting the balance between quality and rendering time. at the moment I am getting a half hour a frame. I am trying to get it down to about 10min.Is there anyone that can help me in any way.be it some settings or friendly advice as the dead line is approuching and sure you know the rest yourself.

many thanks

Patrick

i'll tell you my method, i use medium irradiance as primary with the incremental option so you can get the process by 10 frames, so you reduce calculating time, secondary qmc default settings, one time for house interiors in a hurry i used low settings, i don't know the reason, but it cleaned splotches, the medium solution was darker and splotched, low did great and balanced job, only used vray lights in the windows and fill lights in the center of the rooms

 

normally, you have to avoid materials with lots of reflections, you have to sacrifice quality vs time sometimes, so you can have greater number of objects without slowing down or eat memory, vray proxies are very useful too, but if your materials are highly complex you'll suffer, play with reflections max depth and try to optimize render times with it, the making of a detailed storyboard is a plus, because you know what is the animation about

 

try an irradiance map with half the resolution you need without rendering final image, storing every 10 or pushing things every 15 frames, this depends on the speed of your camera movement, then you use this map restoring to your final resolution an rendering each frame turning on the final image, this saves you an amazing amount of time and memory

 

hope this helps you, maybe the pros can tell you what extra secret tweakings you can apply like thresholds or something, cheers

Check the VRay section of our forum. You'll see there's a lot of info on that matter there (and, btw, please post VRay doubts there only, ok? ).

I think that vray proxies are usuful just to save polycount memory, not to speed rendertimes, well maybe depends on the scene but do not coutn too much on it.
