Pure white plane (floor) with Shadows of Daylight

[Anonymous]

Hi Experts,

Can you please suggest how to have a "pure white" as a floor (plane) with shadows on it and using daylight system.

Attached pic will give you the idea as i have assigned "pure white" material to plane(floor) and after rendering it is turning a bit grey rather than pure white.

Thanks a lot in advance.

daylight system uses the physical orientation of the sun in real world so the color will vary on sun's location. meaning it cant give you the exact white color for your ground plane.
(see figure 1)


to mimic the effect, you can adjust the intensity amount
(figure 2)


or adjust the exposure of the rendered images either by photoshop or by 3dr party plugins within 3ds max, here i use Virtual Frame Buffer ( VFB)

Hello there.

With Arnold:

You can have complete control over the ground color no matter what angle the sun has by injecting a shadow matte shader into the matte closure and feed that to the plane.

This returns a situation where you can override the background with an abitrary color, and it will be fixed no matter what you do with the sun positioner.

you need to adjust your "White balance"

just like in photography, every image gets affected by the colors of the main light and the colors spill from the environment and objects in the scene, Image a white room with a redwood flooring, the ceiling will look reddish.

Adjusting the white balance in your exposure control with doing just that, will tell the render what is really white and balance all the colors in that direction. Now, this has its limitation of course, but that's what it makes it look real.

If you need to bend the rules then you can do other overwrite trick with shaders and so on.

White balance can be found in any modern render engine, Anorld, VRay Corona, Octane and all of them.
