1st Day trying Mental Ray

[bully712]

Hi all,

 

I originally posted under the Viz topic asking about 3rd Party Renderers, but now that I'm trying MR I thought I should post here.

 

Long story short: My employer is renovating the office and they want to study IES lighting throughout the building. They also want to see the effect outside indirect lighting will have on the IES lights.

 

Attached is the easy part of the building because the whole wall is windows. I'm concerned about how the light bounces in the other part of the building but I will get to that later.

 

So in the image attached, how do I smooth out the transition between the hard light on the floor to the rest of it? The part that looks like I used the dissolve tool in Photoshop.

 

 

Thanks

Increase the sun samples. Default is 8, try 12 or 16 or more. Good job for your first day.

Yeah, you are off to a good start. Don't forget to try the MR A&D material, as things like rounded corners and ambient occlusion can make a big difference (I'm not trying to rush you on your first day mind!).

Thanks for all the replies. I'm still having trouble with the areas within the red. I feel that it is too bright in areas that should be darker, like on the ceiling beam, and the shelfing under the desks.

Great Start Mark

 

Look start changing the parameters on the Initial Fg Density to 3 to 5, it will clearup some of the areas with blurry spot or noise. I would keep Diffuse Bounces to 3.

Try changing the softness of the Sun's shadows to about 7-10 and when you do your final renders put the shadow samples up to 200-300 ;D
