Whats your average rendering time in vray interiors?

ecastillor · June 20th, 2005

My interiors in vray tend to be on the slow side....

Especially if i have the knick knacks like Blury refs, displacement, refractions, fresnel refs,vray lights,area shadows,hdri, etc...

In exteriors, vray cuts trhough renders like butter, but the interiors take about 4, 5, 6 hours or more to get a decent resolution.
Is this normal?

How can i seepd up interiors?

lightscape used to take no more than one hour for the same kind of images, but is way too obsolete now..

If I can bring it down to 1 hour per frame, I'm happy. There are things you can do to speed it up without killing the quality. Though I have a small render farm, without that I would be toast.

I am working on one image and its 4 hours. I have a lot of stainless and I have glossy reflections on them. What I have works but I may try to work backwards to lower the settings till they look bad. I never know if the settings I have are too high and could be optimized.

Well, if you run a low resolution prepass, save out the IR map and then run a full pass along with a seperate pass with no GI - only complete specularity for a reflection pass, you can keep frame times down.

well, I guess the question that really needs asking is: "is this an animation or still???" For a high rez still 4,5 or 6 hours isn't too bad. I've had some stills render for 40 hours, of course they are like 10,000 pixels wide and such... For an animation I always render out the irradiance map first. Saves a TON of time.

John, Can you give a more in depth example of doing this?

But on the other hand with Exteriors you spend many hours doing the environment, so there you have the compensation with Interiors!!
