  • Animation tips needed!

    Hello everyone,

    I’ll be doing my first animation (architectural/18min.) using Vrayrender very soon. It is a project that I’ll have to have finished by the 20th of June.
    As it is the first time I’ll do this with Vray and I also have a tight deadline, please elucidate me on the most import aspects that I should consider.

    Thank you in advance for your help!

      I am doing the tutorial, but the point of this topic is to get some advice in what to avoid...Do you know what I mean?! You always encounter some little problems that take ages to solve.

        You must know first if you have moved objects (it's more complicated if you have this). How have you making your setting?
        In fact you must do your best setting or near and keep in mind that your final render time will by less than it because the irmap will be in memory and you will haven’t to recomputed it.
        You can use the tut in the vray help, there is many way to do that.
        But in all case you must save you irmap or photon map or lightcache.
        if you want to make for example with first bounce irmap and second photon map you must save the different map like this:
        for irmap you have the "mode" and the "on render end" in the mode you set incremental add to current map, in "on render end" you check all and you click on browse to make the way to save your irmap.
        the way is to flash in different position lighting (it's a simply definition) like a texture baking so you must calculate some frame of your animation and not all.
        Example: if you have a scene and a camera which only turn around a cylinder you can just compute 4 or 6 image in your animation so you have enough viewed the object, OK?
        In the render common parameter you can adjust it. you can skip image, you must keep in mind that if in all of these image a part of your object isn't seen you will have bug ( I don't speak about flicquing but GI bug).
        this is right for irmap but lightcache is different.
        So, first you set the frequency of your image skipping, 2 you save the target of irmap, 3 you check don’t render final image in Vray global setting, 4 to save a photon map do the same thing in an other path, (antialias isn’t take in count during this computing and you don’t need to save your images so don't care to the message animation will be lose or something like that ).
        Then render the sequence, when it is finish close the render tab and reopen it, now you can view the size of irmap and photon map inside and the “from file checked” of course it means that you mustn’t need to recompute it.
        So you can unchecked “only compute GI”, adjust AA and render the final full animation. If you have a big scene make proxy etc….
        It's a first approach and I hope that it could help you if I haven’t make a mistake or forgot something, but I can edit this post again to add something .

        And other member can do

          Thanks priad!

          I have done the help file and taken in account your indications. I guess I am just a little bit nervous, because it’s my first animation using GI. Well…I hope it all goes as planed.

          Thanks again for your advices

            Very interested in your progress and any problems that may arise. I may also need to do a similar project very soon, or at least price one. Please give updates as you progress. Thanks.

            Good luck.

            Regards Peter.

              Material properties can be critical for getting your frame times low enough. One slight error in a setting for a frosted glass material almost blew the deadline in my first VRay animation. Glossy reflections and refractions can be costly, and they can be deadly if you have your subdivisions set to high.

              If you are using version 1.4* instead of 1.09, remember that the subdivisions should be around 8 instead of 50. This was one of my problems as I had downloaded a material library from these forums, and all of the materials were for version 1.09 with subdivisions set to 50.

              I like how the tutorial keeps stepping you back in and having you render a single frame to make sure that everything works correctly. If I would have done more of this with my first animation I wouldn't have lost as much sleep trying to get it finished.

                I forgot to tell you that the project was ready on time despite some minor problems. We had to do a 15 min movie in 30 days, but the client took a long time to send us the plans so in the end we had 15 days to do this. Needless to say, that the 5 nights before the dead line we had no sleep.
