Vray distributed net rendering?

Craig Ramsay · April 10th, 2003

Can any of you guys tell me how well the Vray distributed net rendering works and does it re-assemble the image afterwards like brazil?

Im looking at geting Vray for a large project that we are doing instead of buying another licence for brazil.

Cheers

Craig

You may want to take a look at the official vray forum..
Vray DR setup

You may need to register, but is free..

A few things to note about the current distributed rendering.

How it works:

Similar to the way Mental Ray does it, it sends buckets over the network to render. Therefore you can use up to 10 computers to render a single images, and it is being rendered by all the computers at the same time. Each of the buckets has the name of the computer that is rendering it so you can see who is rendering what bucket. So if you have 10 computer each witth 2 processors, you will se 20 buckets rendering your image.

GI and distributed rendering. When using the fast and preferable method of doing GI, where you use irradiance maps and use the single frame mode, this process of the rendering is not distributed.

How do you get around it:

- set the GI the bucket mode... advantage, all the processors will render each of the irradiance maps in the buckets... disadvantage... you will see seams between the buckets... this is really just good for previewing

- calculate the GI on one computer save the irrdiance map and distribute render using the saved map.

- use direct (or bute force)... this is slower, but with 20 procs will end up being faster and look really good.

I tend to use the brute force qmc rendering with brazil anyway as it doesn't have an iradience map function. I just don't have enough licences for my machines at the moment

I have not tried it in the latest build of Vray, but keep in mind that the latest build, version 1.09.02u has a much better bucket mode so the seems should be much less visible supposidly.

i alway use DR in vray for my large stills. the setup is very easy and it works great. not just in the bucket mode. there are several ways how to work with vray and DR. look at the vrayforum

hi, the link seems to be dead.
it is not easy for me to set it up, I get black screen. Do you have to calculate Irradiance Map first before you use DR?
can you tell me how you set it up?
thanks.

Yes save your irradiance map on a shared network drive along with all your material files...
