Bathroom

[Simas9]

Hello, now I'm playing with bathroom interior:



CPU- Pentium D
Settings - qirmap_medium
Lighting - sky, multiplier-3

Render takes 4h. and 20 minutes

Can anybody tell my about, lighting, thats wrong ?
Or I just had to make multiplier bigger ?

Re: Bathroom [HELP]

I think you should leave the sun multiplier at 1
and change the iso value to 800, and shutter speed to 60 or something.. To add more light to the scene..
Or should it look like the lights are off?
Just try different settings until you have the right result.


And i don't know if you use a lot of displacement maps?
Those usually takes a lot of extra time to render.

Re: Bathroom [HELP]

Thanks I will try.

About lighsts, you mean rectangular, omni..?

Re: Bathroom [HELP]

I don't know how SU works with lights.. In rhino rectangular lights are fine.

I only know that the iso value and shutter speed are very important for the brightness of your rendering.

Re: Bathroom [HELP]

How many sudivs did you set for the light cache ? I think this link will help you: http://www.spot3d.com/vray/help/150S...lightcache.htm
It's explained on Vray for 3ds max but principally it's is the same.

Re: Bathroom [HELP]

well i think you maybe try with prefilter in light cache

Re: Bathroom [HELP]

Thanks I dont think about that before ???

Now I'm try to set Subdivs-1000 and Sample size 0,01 it helps



Now I have a problem with light reflection on the ground, how to make it lower ?

Re: Bathroom [HELP]

i see you are having some trouble with light, is it a closed room? look i will upload the visopt of the chairs render i managed to get good quality shadows and no artifacts on the light, a bit slow tough.

i created that visopt for this render

now if you want it to have daylight and not controlled rectangular light i recommend you to use vray sun, that way with very little effort you can get light to reach anywhere

in this bathroom i used GI with vray sun, if you wish i can share with you or anyone interested my visopts. feel free to contact me via PM.
