Help! - Camera Animation and Network Rendering

[Nick DI]

Hi, new to Vray (but learning fast... due to looming deadline!) Unfortunately the tutorial for a walkthrough animation is not in the current manual. What I need to know is what do I need to set in the Irradiance Advanced settings for a flythrough sequence and do I need to install anything on my render farm for network rendering of about 800frames? (not going to be using DR). Currently running Max 6.

Thanks in advance

Hi

it depends a bit on the version of vray you use. (1.09 or 1.45xx.)

most important is to let vray save the i-map incrementaly.

1. Go to the Renderdialog and switch to render every tenth or 20th fr., depending on the speed your camera has.

2. go to global settings, and turn on , dont render final image.

3. switch on your rendermethod ( lightmap with i-map ) ore (quasi montecarlo with i-map), in the advanced settings of the imap switch on "incremental add to current map". this is the most important step, and also : on renderend, auto save to, and switch to , wherever you defined your i-map to be saved.

4. after calculation switch of again: dont render final immage, and turn on again render each frame.

go for it

And how do you manage to save the lightmap to be used for rendering on multiple machines. I know you have to have it set to Fly-through - but how do you save this? I've just come back to my machines after the weekend and found that only one is still rendering because the others had the message :
cannot create file that already exists.
I think that this is to do with the lightmap, but i am only speculating. Any thoughts?

Sorry sv

i havnt been in the forum a while, hope i still can help you.

Well the lightmap still cant be rendered in the network. so what you have to do is the folowing.

just render your scene one time in animaiton modus on a single machine. just do the lightmap and nothing else. switch on dont render final image. and now after your job is finished, go to the lightmap pannel. what here in the current 1.457 is missing is a button like in the i-map rollout, that gives you the abillity to automaticaly save your lightmap and switch to it.

so you have to do this by hand, directly after you rendered your animaiton.

this missing thing will be there in the newest build. in 1.4578 you can save your l-map automaticaly.

save your l-map to a network path where all machines can get acess to it. now point your lightmap path to it, and you will be able to use it for network things.

one thing also, when you use l-map for animations, you have to switch to animation, but also in the mesurement from screeen to world.

god luck.

Is this the Reference coordinate system you refer to Tom? It is currently on View - not screen, if this is what you mean.

Thanks for your reply

sorry i was a bit unprecise,

i mean the settings in the l-map renderdialog.

in the calculation parameters,

theres a switch for the scalle. switch from screen to world. if you move.
