  • Saving Irr Map on a Renderfarm

    Hi...can anybody show me how to render an Irr Map for a walkthrough using a render farm? What I have done now is to calculate the Irr Map on one pc and shoot the Incremental add to current map to 6 pc's on the render farm, but I am not really sure if this is how it is done...An emergency please, so an early response would be great and highly appreciated! Thanks in advance!
    Show me how to do that...please!!!

    its always best to calculate the irradiance map on one machine. Then send the actual animation to your renderfarm loading the saved irradiance map.

      why not just use DR? you can calculate irradiance maps with DR for flythroughs. i do it all the time

        and if something goes wrong with one machine during that DR process, its likely his irradiance map will be bad. No Id recommend the safe way, use one machine.

          Have u tried to send a DR IM calculation to backburner? Or this process should always be done locally?

            backburner isnt involved with DR

              Also, AFAIK, incremental add doesn't work over DR. I've found that on my small farm (4 machines) it's much faster to use the incremental add on one machine than to recalculate each frame over DR. This may have changes in 1.5 though, I'm not sure.

                Start with no IRmap, set it to multiframe incremental and the rest of those settings and render it on only one machine, then let the ani pick up that IRmap file and youre sorted.

                  strange. i did a flyby animation on an island recently and the irradiance map was calculated on my farm of 6 systems. this was with a 1.49.x version though. so maybe vlado disabled it when he went 1.5

                    Its never worked for us, going back to 1.47 - after each frame is saved from a new node it overwrites the other ones instead of merging them together before saving.

                        Ahh, sorry, I was talking backburner.

                        Not used DR yet.

                            never tried to calculate GI solutions, but when testing a small animation some slaves droped the render once and a while...

                              What im talking about is exactly that: using backburner to manage several DR IM calculations with incremental ADD to current map. I dont like the idea of having my local workstation locked because of a DR. This is the work rendernodes should do.
                              AFAIK, vray 1.5 can render incremental IM too, but my farm is too busy to try and calculate a DR Im test, mainly because DR doesnt care about if a rendernode is rendering some backburner tasks or not; it will send the part of DR to that machine and therefore will make it crash if that machine is already working on some other scenes.
