first interior in vray

[silverioneto]

hello guys,
im here on more time to ask you some advices about time to render. Im not so experience in interior view, so , this is one of the first... and if i cant getting better with times, it will be the last. I explain why, This should be only a test, but takes 5:30 HOURS . I cant spent the whole day wainting for a test.... i was thinking to save irradiance map and use it in final resolution, so my settings was : -3 0 / .3 .3 .1 / 20 60

now please, give me a solution to decrease this so crazy time

Hi...

I think u can change that to -3 -1 / 0.5 0.5 etc
but if u can please tell as more about the scene - like what lights u use and more

best thing is if u want it - send me the file and i'll try to tweak the settings to get faster result.

what system do u render on ???

regards,
bakbek.

The time was that high at the resolution shown? That is high, as above
perhaps some more information about the scene or the scene itself
would help.

And what pc are you using?

Also, what took long, the irradiance map calculation or the rendering itsself? With for example vray area lights with high subdivs, high AA settings, glossy reflections with high subdivs etc... rendering can take very very long!

hello guys
thanks by replay but i found what was wrong, was the floor material ... it was taking too much time to render. Here is another update, but i would like to know whats hapen with reflects... sometimes they appear, sometimes not... this image of very hard for me because i havent experience yet, because this , i know that it has plenty of problems..., dont know why some objects are showing too dark, and i had also a problem with background: i did the irradiance calculates without glasses, and everything was ok, but when i put glasses to render the final image, they stayed too much lit, and i could not see background, as you can see below...

I believe your glass needs to be on when calculating the irradiance map, that might be one of your problems with the reflections, but you still have failed to mention what light setup you are using which may also play a role in problem solving...

when i test i drop set the samples from -3,0 to -3,-3 and drop the hsphere and hsubdivs from 20,60 to 15,15...that makes things faster. Also i globally limit my reflections to 1 and set glossy samples and area shadows down to about 3. All this helps make the test images run faster, and as i get stuff sorted i wind them back up.

Your bg problem is because you probabely use color mapping with affect background turned off.

Without windows, you see the bg, untouched because 'affect bg' is off. When you add your glass windows, the bg is affected, because it's not bg anymore but bg refracted in te glass, so vray considers it as an object and not as bg anymore. There has been several posts about this problem before (not so long ago). i'd suggest to do a search on this forum for that.

thanks by replay, will use all the advices and as soon as i finished, post here for you see. I had anothers problems... the architect change almost everything so i will need to really recalculate the whole image

anyway
thanks for comments

Hi

Another very useful tool, to reduce Rendertime, while making up the overal lighting of the Scene, is to use the QMC Sampler.

Standart settings down there are 0,85 0,005 and 15.

If you make them for example to 1,0 0,1 and 5,

you get a very fast preview about five to six times faster than standart settings. Of course Quality isn´t very good. but for the first setups it is very good. after this you can go on with standart settings.
