vray has gone nuts?!!

Ok, so I'm working on my FIRST interior shot :D . I've only done esoteric engineering aids thus far and decided to learn how to do "other" visualizations. IN ANY CASE....

 

I'm using 5.1 and vray free to render, but with radiosity enabled, I get a really funky result with vray. When I don't have a glass wall (either a solid wall or blocks), the rendering, though slow, works fine (see example filepush.asp?file=example1.jpg . But with glass, the pict goes crazy (see example 2 filepush.asp?file=example2.jpg

 

 

I'm at a loss :???: ..HELP ME!!! HELP ME PLEASE

ok, they said the same thing but I'm a little confused.

 

How exactly do you create a glass material without using raytrace? when you say to not use the raytrace map, are you referring to the entire material, or just in the reflect/refract maps?

Both. If you want a reflective or refractive material using VRay Free you have to use the VRay Map reflection/refraction in the appropriate slots of a Standard Material.

ok, so here's what I did:

trans shader material

 

basic Parameters:

diffuse level 100

self coloration: 0

spec highlight: 0

Glossiness: 40

Backside specular: on

opacity: 27

 

 

here's the accompanying pic:

filepush.asp?file=whatIdid1.jpg

 

and here's what came out:

filepush.asp?file=Snapdragonbathroom9-vraymat.jpg

 

Another weird thing I'm noticing is the strange coloration of the picture. It's looking more and more like an NPR (not that I mind), but I was wondering why this is happening.

 

The radiosity solution is set to 85%, with everything else default. My Environment settings are Automatic Exposure control active and processing background and env. maps (though if I try to hit render preview max ALWAYS (100%) crashes), with brightness and contrast set to 50 each, exposure set to 0, and physical scale set at 1500...and desaturate low levels is on.

 

As for VRAY:

Adaptive subdivision: -1, 2

GI: on

refractive/reflective GI caustics: on

first diffuse bounce: 1.5

second ~: 0.5

irradiance map:

hsph subdiv: 50

interp samp: 30

direct computation:

subdiv 1

depth 3

irradiance map preset: very low

GI Env. override: on @ 0.25

GI reflect/refract: on @ 1

 

This last one took a total of 4:22min to compute

 

 

sorry for taking so long to respond

What are you doing exactly? Are you running Max's radiosity in conjuction with VRay?

 

Also, What's the reason for using the Translucent Shader? I've never used Max 5.1 but I'm pretty sure using that shader will complicate the situation much like the Raytrace Material.

Mark,

 

higher imap setting? I'm not sure I understand

 

kid,

 

don't you have to run them both for a radiosity solution?

 

as for the trans shader, the only reason I'm using it is because it was the only standard material type I know that has translucency.

Let's clarify things a bit. You CANT run Max's radiosity solution AND Vray's GI AT THE SAME TIME. It simply doesn't make any sense! Choose VRay as your current renderer, turn it's GI on and be happy! :D

And check out the various VRay tuts you can find on the web. You'll see what we're saying here.
