please help me with my first Vray scene!!

[ant_sutton]

Hi guys

 

I have created small dining room in 3ds max and rendered in vray. However, I keep getting high contrast black and white patches and other strange marks around the window. I have attached two pics of the problem. Any help would be greatly appreciated.

 

Also, might be too much to ask as I'm sure your all very busy but I have attached the scene file so you can check my material and vray settings. If you look at this file, any pointers on incorrect settings I have would be fantastic

 

I'm thinking some settings are quite wrong as to render the scene with all furniture takes around 5 or 6 hours. The scene will only the walls and lights seems to take a strangly long time too.

 

thanks alot

First off the materials were set way too high for the subdivision. You had 50 on both reflection/refraction for most of the materials. I rarely go over 15. Also the bg was still reflecting black that may have been most of the black splotches. The glass for the door was not a vray mat while the windows were, I just got rid of the standard mat version . The diffuse multiplier was set to either 300-600 for the vray lights. I dropped that down to 100 for each light.

 

I set this to Low default for irr map and set the h subs/interp sapmles to the default of 50/30.

 

I changed the second bounce to light cache and put both first/second bounce at 1. I changed the skylight color to match in bg/vrayreflection/environment.

Also just for this I turned the AA to fixed. This rendered in 9 minutes 04 seconds on my dual 2.8, 2 gigs ram. Any other questions let me know. Unfortunatly you must be on an older max version thatn me but if you can read a 7.5 file let me know & I will send it out.

hi sawyer.

 

thanks alot for your reply. I knew I had some settings really wrong.

 

I tried with your settings but I still couldnt get the background colour right - its now coming out red. I obviously didnt set any background/ environment colours to red and there were some strange patche still. I also tried using the lightcache for bounce 2 but the image turned out a very washed out ornage colour.

 

I have a attached an image of my first attemot, without light cache.

 

any help from anyone is greatly appreciated

 

cheers

I don't know what that trouble would be. In the file you posted the plant material was causing problems so I removed the plant. It doesn't seem like the scene you posted is the same as the last image.

 

What version of vray?

 

If you are having problems it never hurts to add a material overide to the scene, then hide the glass panels. This will narrow down the problem to scene settings or materials, I would imagine its something with the materials you have. Really I would be more worried about that table as I don't think you could have your knees there. Also the chais are floating a tiny bit above the ground, you would notice it on a large print.

 

I dropped the irr map to the preset "very low" with 30/20 h subs/int samples. Light cache at 300, I also dropped the QMC min down to 8. This took 5:29 to render.

hi sawyer

 

thanks for your reply. Really helpful again. I adjusted the settings similar to yours, but I ma now getting a black background again outside the windows and is reflecting into the room. Could you please explain the settings you used to create a white background?

 

thanks for all your help. And yea, I think the table needs changing. lol

 

thanks

5 MIN. Remember to change the reflection in vray environ to match the skylight.

hey sawyer

 

thanks for all your help. your settings have worked really well. I just had to delete and recreate the vray lights and the black shadows dissapeared.

 

I've learnt from this though
