vray render

[Boizell]

hi , this is my first render using vray, its a residential building designed by a local architect..

it took 13 hours 28 mins to render 1200x900..

 

my question is how can i reduce render time to a logical limit? or is it by any chance normal??

 

here is the image and the settings i had.. and CC r welcome of course

 

thank you

1st off - using adaptive QMC is ok but i think the settings of 1 / 15 are very high and can be reduced. i usually adaptive subdivision at default setting, i know people tweak it but never by that much

 

2nd - Quasi-MonteCarlo GI defaults at 8 subdivs and 3 secondary bounces, you have 15 and 10, this will make a massive difference on render time. the secondary bounces are nice to turn up, but it will cost you

 

check out http://www.spot3d.com for some advanced understanding of settings

 

the image does look nice tho, unfortunately its too small for a decent view, can you post a larger version, also let us have a look at your Irridance map settings and tell us at what size you render the image at.

May want to check your Irradiance map as well.

here is the irradiance map settings and as i mentioned above the image size for the render was 1200x900.

 

the file size limit for this forum does not allow me to upload a larger image...

Yeah.. the high setting is better suited for animations. For a still you can use Medium. Even set your Subd down to 30 or so. Combine that with the othe suggestions by James and you will see a huge increase in speed.
