Thanks, I think I have read this somewhere before! But I didn't think about a few of the setting you point out. I guess I should read into some of the setting a little more to better understand what it is, and how it effect the scene.

Mr. Everett, I was asking about the mapping on the fascia because that could be the reason for having some colorful spots there - and the irmap settings of course. There is no need of displacement since you don't have a close-up of the fascia - bump is faster in this case.

Matthew, what do you suppose fixed it? Also, what external lighting method did you use - that could have been part of the problem. I just noticed your grass btw - excellent material!

update!

Thanks Guys for the active questions and posts!

The grass was added in Photoshop, as I have yet to see a good grass material, I have been working with the hair modifier, but that causes horrible render times.

TishoChaos:
The material on the fascia is just a standard color with a wood bump map of my choice, since the object is so far away in the shoot,, the detail isn't picked up. I wish i could get it to pop a little more, as it would add that much more realism. The bump on the siding wasn’t giving me the detail I was looking for, that is why I jumped to a displacement map. Even after the fact I have changed the material on the siding per my client, now I am just using a bump map only,

jujubee:
I took the advice of fellow artists, in this forum, I have bumped up the Interp samples, I also adjust my global reflect map, as it was creating a undesirable result. I do think the global reflect was a cause of most of the issue! I still don’t know for sure, as I have 1 annoying spot left above the front door!

As to that spot I can not Figure out why it is there, or where it is coming from, also under the far eve on the boxed window there is a funky dis-colorment happening!



My lighting break down:
Main lighting: Standard Max Direct light with Vray shadows
Interior lighting: I have 5 Vray Plane lights at multi of 5.0 to 6.0
Vray Environment: GI Env. "Skylight" Standard Setting 1.0 Color White

Am I missing something in my setup of exterior lights? I am doing this on how I got it to look right! I don’t know if it is the right or wrong way!? "Someone please comment on this"

I am working with the reflectiveness of the windows! I just lowered the reflect, and boosted the refract....! Is that what you would do?

Thanks again guys for all the help! I think I have come along way since the start of this issue! I have also been reading what each object within Vray actually dose. & I am testing myself on it, so I have a better understanding on how each setting affects the light and lighting
