Vray proxies in animation-too slow

[Boris Horosavin]

hi,

in my renders I often use Vrayproxy, mainly for grass, foliage and similar stuff and it worked perfectly for me. however, for several days I've been trying to compose an exterior animation with Vrayscatter-made forest using pretty much standard sets (light cache:fly-trough/irradiance map: multiframe incremental). without vrayscatter it works OK, but when i activate it things get painfully slow. of course, I'm aware that the problem comes from too many polygons and not vray proxies , but, on the other hand the scene is realy not oversaturated with proxies (there are just several spots of shrubs and trees). bottom line-with all elements turned on animation consisted of 1200 frames takes 10 days or more to render (I wasn't stubborn enough to wait and see exactly how long ...) my experience with animation is very limited, so I'm asking if I am doing something wrong and if there is a relatively easy way out. note that I've already simplified proxy objects and textures as much as I could. thank You.

 

ps oh, yeah, all the elements in scene are completly static

Hi Boris

 

there are two things I would check, maybe you did it already.

 

Select all the greenery objects (shrubs, grass, trees, ect) and turn of generate GI in their vray properties settings.

Then, check you're bitmap settings for you're textures for the vray sctatter object. set the bitmap filtering to none. Also I won't advice to use refraction and a vray scatter object as it can increase the render times as well

to be quite honest, I didn't do any of this... i will set up these changes as soon as i can and report with my results. thank you very much.

There is a section for Vray.

Also, how many IES lights? ....maybe try making these not effect the proxies if the proxies are not close to them. IES lights are more intensive as it is, and lots of IESness can hurt render times if you are not careful.

 

Also, unless necessary, don't be afraid to make the proxies not visible to reflection/refraction.

thanks, Koper & Crazy Homeless Guy, I followed your suggestions, basically lowering the quality of proxy objects to gain on rendering speed, and it had really quickened things significantly. the trees, however, did loose some of their charm, but I suppose that's not a big problem since they are far off in the background. nevertheless, the rendering will take several days to complete. and if that is to happen any time soon i will post the results. so, in conclusion I would say that relatively complex animation in Vray is hard task for standard, single machine, unless you have all the time in the world.

yeah, and DelfoZ, sorry, I know there is Vray section, but I was also looking for some more general answers, for example: can I try using Mental ray and it's proxies and materials for faster results? and also, can I maybe try using VUE (which I had never used before) to generate background coulisse, thus excluding proxies from the scene. I work with the Cultural Heritage Preservation Institute and we mainly deal with forts, crappy old houses and similar, and that sort of scenery asks for lot of foliage (example attached). thanks again.

nice

second imagen really looks nice, glad u post this images here, bcuz i never read vray forums

 

PD: I don´t use mentalray for animation and to be honest im afraid to use it , right now im doing a personal project based on a scene from kickass(the movie) and im gonna try to make a video, and i didn´t want to sound mean with my comment, but there is a lot of Vray experts that only read Vray forums so maybe you can get more info there.

 

Have a great day
