Vray+Sun problem??

[christitan]

Hello there,

 

I'm a bit new to V-ray and here is my first question:

When i use V-ray Sun to light a House ( my own ) and use standard materials ( like Vray MTL GREY) all goes right, but when i change the color of the ground box to say grass.. the complete building turns into a green shade... like the sun is reflecting the color of the grass onto the house...

Can anybody tell me where i can change such a thing?

 

thnx alot..

can you post screen captures of your settings and a render showing the problem.

try using the vray override material

Hi,

 

If i'm using the override material all turns grey, i just want to use Textures to make my home "realistic" , but when i textured the groundfloor (terrain) to grass it reflects the light (greenish) onto my home, i just used a standard material and added a grass Bitmap to it (Diffuse)

 

When i change the diffuse of the terrain to let say purple there is a purple "glow" to my house... even when i put a box near my house and give it a color , the color glows onto the house..

 

i'm at work now, tonight i will post an image of it...

 

for now Thanx alot

its called colour bleed, and is being generated by your GI solution, there are numerous ways to get rid of it, i should have gone into more detail about the vray override material, when i see your scene i'l set up a similiar one to show you the difference

use LWF

[Dave Buckley]

nic nic, you better hope this guy knows what your talkin about when you say LWF, otherwise you got a lot of explaining to do

[Eric Sosa]

use LWF

LWF = Lets Wait Friend ..... or...what LWF stands for?

 

nah, it means LOW WORK FLOW. I suggest u to learn first the basics and then u can start thinking about using "low work flow" in your work ..... a little later.

[Dave Buckley]

Low Workflow?? I thought it was Linear Work Flow

[christitan]

I read something about LWF but didnt got to use already, i seen alot of Tutorials using V-ray for interiors or exteriors so the basics i know ( unless these Tuts. are incorrect ) i shall experiment tonight a bit longer with the settings of the V-ray Sun...

The scene is just too simple, a simple house on a box , with an V-ray sun and Physical camera thats it

If you're using Global illumination (Indirect illumination) then try lower your secondary bounces (the one below). Otherwise send your scene to my mailadress and i'll take a look for you.

 

Groeten,
