The link below is to a image which shows the kind of lighting i am tryin g to create.

yeah- look at my signatuer (fav work in maya), its not as good- but whatever.

How I did it-

I went to www.cgtalk.com and into the Maya Rendering Section- VRay Style Renderings With Mental Ray.

And I read about half the thread (took a good 3 hrs to do that). That taught me 'nuff!

Hope that helps

I have started to model and render a vray style interior

i have managed to get somewhere by reading the forum that matt recommended thanks matt very usefull !!!

i have basically modeled a empty room and have created to windows on one wall of the room next to each other i have managed to successfully illuminate the room using final gather global illumination photon immisions all this done by two mental ray area lights acting as the main source of light coming through the windows i created.

heres my question does anyone know how i can create the rays of light coming from my area lights i have used for my windows ? basically sun light rays coming through the windows and into my room !!!

Do i need to attach something to my area lights?

Plz Can someone help !!!

yeah, well, what I do is I have a far away spot light as my sun source, and I use the area lights outside of the windows as sources for my ambient light.

hey no problem.

All of the materials are Mental Ray materials.

DGS for all but the metal on the chair- the DGS with specular and glossy on 0. The diffuse is the color.

Dilectic Material for glass- color is the col, and the IOR is Index Of Refraction. Glass has IOR of 1.52. Diamond has IOR of 2.3. Air has IOR of 1.0002. A vacuum (no air, no nothing) has perfect 1 IOR. Water is 1.3.

Hope that helps,

Yep thanks for that matt but the thing is i apply the dgs material for the walls but when i apply white for the ceilings or walls it doesnt look like its white like the white in ur interior render? i really do not know wot im doing wrong!!! when i render my walls which i want to look white they look grey.

i will attach to this message my render of the project and also after i will attach the maya file and maybe u could download it and work with it and see if u can come up with any different results.

Umm, can you post a .MA version, since you have Maya 7.0 and I have 6.5, I can't open your file.

If you post a .MA, then I can edit the file header and it will let me open it in my 6.5

And then I would gladly look at your scene.

Later,
