  • irradiance=> qmc / net render irradiance maps

    hi all,

    was just wondering,
    if the qmc lighting method is essentially "unoptimised" and the irradiance map optimises the calculations, i would assume that an irradiance map with settings of 0,0 would be equivalent to a plain qmc render? if that is the case, what do positive values for the irradiance map do? i assume it oversamples the image, so 1,1 would give you the equivalent of a qmc calculation on a larger image..?


    secondly (greedy two questions in a post!)

    ive seen that the new vray saves the irradiance map every frame, which is great!, however, i need some clarifying as to how it actually behaves...

    if for instance, i set a lighting calc going on a single machine on our network (net rendered so if it crashes it will restart..)

    basically im wondering if when the machine crashes, and reloads the job, does it start from scratch on the irradiance again, or does it start from the last rendered frame and load the irradiance map that was previously saved? only reason i ask is this would reqire max to switch from "multiframe incremental" to "incremental add to current map" as well as loading an irradiance map first, neither of which i imagine backburner doing....

    also if it crashes, and starts from the last frame rendered, and stays on "multiframe incremental" you will lose all the lighting info for the first part of the anim, and it will calculate only from the frame it crashed on... which could cause a whole heap of headaches...!

    anyone any ideas?

    no one a clue? this stuff isnt really covered anywhere as far as i know (someone tell me otherwise!) so if someone from chaos could give some pointers, that would be nice!

      Why don't you try to read the online help on the LOGIN site - there you will find a good description of what is irrmap and qmc and how do they work since I sense that you are quite confused now. If after reading the help, you still have some questions on something that you didn't understand - I will be glad to clarify it for you if I can.
      Best Regards,
      Tisho

        hmm.. i didnt look at the manual for quite some time it seems...

        works just like i thought.. cool

        however, 2nd question still stands... anyone can clarify the irradiance map behaviour when net rendering?
