render in vray

[rachelC]

i was wondering if someone could point me in the right direction? i am having my 'debut' using vray advance. in the attached scene, I have 1 vray light with a multiplier of 1.2 white to light up the facade. could you tell me how can i get the white render on the facade to look white please?

 

Many thanks

maybe you forgot to turn the light on? or maybe it's shining on the back. see the small back roof is white

nop. light is definitly on. i can see that the roof is white and it's the same material that the front facade. any other suggestions?

switch to Vray shadows instead of raytraced shadows.

problem solved

did you uncheck your default lights on global switches parameter

Have you tried upping the multiplier 1.2 is a bit small for a vray light.

Also make sure the light is facing the model to illuminate it well. If the back roof is being hit the illumination may not be blanketing the right areas.

thank you for all your help. by increasing the vray light to 2.0, i got the following render. Now, i have added a direct light (with ray trace shadow) to my scene as well as the vray light to try to get crips shadows. could someone tell me which settings this light should be for best results please? eg:

the setting in the indirect illumination settings and also general parameters?

In fact, any tips to make the attached image better would be brill.

many thanks,

The default settings are a good starting point with VRay.

 

Your direct light should be set to VRay shadows not ray trace, never use ray traced anything with VRay.

 

Here's some starter settings for you:

GI ticked

Irradiance map / Quasi Monte Carlo

 

Irradiance Map:

-4 -3 everything else default

 

Environment ticked

 

Your direct light:

shadows ticked

VRay shadow

colour yellow/orange/white

VRay shadow parameters:

transparent ticked

area shadow ticked

sphere ticked

subdivs 16 ( for straters )

Hello There.

Well as siliconbauhaus says, you never should set your shadows to raytraced or any other, just Vray Shadows.

I never put any vray light for exterior, i suggest to put that direct light and set the multiplier lower than 1, and just play with the envioronment override multiplier, and of course the Indirect Illumination, allways Irradiance Map, and for second bounces Quasi Monte Carlo
