Environment settings allow you to control DriveWorks 3D Document properties that affect the whole scene. Settings can affect the lighting, model reflections, background colors and more.
Recommendations when using an Environment Map.
(And leave tone mapping at max)
With Environment selected in the Feature Panel the following will be displayed in the Information Panel:
Checking this allows Use Environment Map Lighting and Display Sky Box to be set.
In the Environment Map section of the Information Panel, you can adjust the parameters: Exposure, Rotation and Maximum Brightness.
Checking Use environment map will allow the environment map to be used in model reflections. High reflectivity models will reflect the sky box in the model.
|No Environment Map||With Environment Map|
Will use the lighting from the Environment Map images. Light areas in the images will appear as light areas on the model.
Will display the sky scene around the model.
Will display the Document's Default Camera. Used to hide the Default Camera when Camera Entities are being used in a Document.
The following settings can be applied to the Environment Map:
This is essentially brightness for the Environment Map.
Exposure is slightly different to brightness, in that it’s applied on a curve so bright parts get brighter faster than dark parts.
Typical values vary depending on how bright the scene is required to be and the image used.
For JPG/PNG images, optimal values will be between 0.5 and 3.
HDRI images can be extremely bright so lower values would be more realistic, possibly 0.1 or so.
This rotates the Environment Map in degrees.
Its main use is when the Environment Map is displayed as a skybox.
Typical values are between 0-360 degrees.
This limits the maximum brightness (typically applied to extremely bright HDRI images, that capture the sun for example) which can play havoc with reflections and bloom post effects. This can also happen if there is a really high exposure setting in the image.
Typical values, can be left at 100 unless the image has bright spots, in which case reduce this value.
Sets the color to use for the background (not applicable when using sky box).
Will apply a hexadecimal value to the Background Color in the Parameter Panel.
This adjusts the maximum value for the tone mapping.
Tone mapping puts color brightness on a curve, so there is more room to calculate colors in the renderer, then bring them back into a range displayable on a monitor. This allows a much greater range in light brightness levels but reduces contrast.
A value of 0 keeps colors the same, a maximum of 1 gives a cap of 5 on the curve.
Typically this can be set at 1.
The image above shows the curve where (in the renderer) brightness is on the bottom, to the final displayed brightness on the left (1 is the maximum a monitor can display).
The blue line is the maximum tone mapping of 1. The red line is the minimum tone mapping of 0.
The curve is x / ( x + 0.187) * 1.035
Where x is the tone mapping value.
Brightness is a literal brightness multiplier.
Typical values are between 0.5 and 2.0.
Contrast shifts colors away from the mid range. So it makes dark colors darker and bright colors brighter.
Range of the slider is -1 to 1. Where -1 will be no contrast and will make the entire scene mid-gray. 0 is no change and 1 will significantly increase the contrast.
