LIGHT WHERE ARE YOU!? /VRAY for SKP

Portugal881

Hi all!

I am new user of vray, but already tired of it! I got problem with my renders as they are too dark, was trying to do different tutorials, but somehow it didn't work that well.

Also weird things like - the glass doesn't show it's transparency - although it shows transparency on vray materials editor..

I am attaching few slides I done specially for that post, in hope somebody will help me..

I have done render a and b - with slightly different tutorials which I found on Google ( if you interested that the tutorial for render a: http://www.youtube.com/watch?v=K-L5APsenhY and for render b: http://www.youtube.com/watch?v=DCIngKllJnk)

My model it's about 65 mb.. which is not a small size. Renders even with basic options take quite a bit and it took me about 5 HOURS to do just a little like that. I am honestly exhausted and have no Idea what I am doing wrong..

see the attachments and if you know the answer to my problems please help!

V-RAY RENDER DEFAULT SETTINGS + i TRIED TO ADD 1 RECTANGULAR LIGHT WITHOUT ADDING ANY CHANGES

Hi Lila,

One quick answer for you: in render "A" You are using "material override", that is why your glass material is not showing. Go to your glass in the vray material editor, and uncheck the option "Can be Overridden"

A more complicated answer: You'll probably want to do some testing with a smaller file sized model, or you will be very frustrated waiting for your 65MB file to render. Since you have an interior scene, I would try to put in lighting like you have indicated in the model. Make a simple model of a similar shape, and start adding in vray lights. It takes a while to learn all the tricks of vray, so the best is to take one concept at a time. If it makes you feel better, my first renders with vray looked just like yours, but it didn't stay that way for long.

Also, I see that you've started making changes to the camera settings, that is important to know, and I would keep adjusting the camera as you make changes to your GI and your artificial lighting so you get proper exposure of your scene.

Lastly, one hint: If you want daylighting in your space, I would use a high GI multiplier without sunlight. In your "Environment" options, go the the GI (skylight) option, and click on the texture (The "M" button) and change from TexSky to "none" Then, after you change the texture, change the value in GI from 1 to something like 10. This will bring in much more light to your scene from your exterior openings.

Good luck

Andy
