Render Environment Map Dialog (Pro/Studio)

Top  Previous  Next



The Render Environment Map dialog, available in the Pro and Studio editions of Genetica, allows you to render and export HDRI environment maps using common spherical panorama map types such as latitude/longitude and mirrored ball.  This dialog can be opened by clicking the Render Environment Map button found in the button bar running across the top of the interface, or by clicking Render > Render Environment Map... in the main menu.



Render Environment Map Dialog

Although you can click "Open..." and select an *.emap file, in most cases you'll want to begin by clicking "Edit Map..."



The Render Environment Map dialog is divided into four sections labeled Generate, View Settings, Export Map, and Result.  These are described below.




Generate Section


This section controls the environment map that is generated.





"Edit Map..." button

Opens the Edit Environment Map dialog, where you'll be able to select or create the environment map to be rendered.

"Open..." button

As noted in Working with Dialog Presets, Genetica's major editing dialogs contain built-in functionality for saving and opening files from the Genetica User Files folder.  This means that you will usually be able to open previously created environment presets from within the Edit Environment Map dialog that appears when the "Edit Map..." button is clicked.  However, if you have an *.emap file somewhere other than the Genetica User Files folder, you can click the "Open..." button to load it.

"Save..." button

As noted above, the Edit Environment Map dialog can quickly and easily save environment maps to the Genetica User Files folder.  However, if you wish to save an environment map to some other location, you can click the "Save..." button.

Map Type

As noted in Environment Maps Explained, environment maps represent a spherical image that has been flattened onto a two-dimensional surface.  There are a number of ways in which a sphere can be flattened, and this drop-down specifies the desired technique.


Controls the size of the rendered result.




View Settings Section


These sliders modify the lighting and view angle of the rendered environment map.  In addition to making final adjustments to the environment map, the sliders can be used to preview the environment in different ways.  If you are using these settings only for previewing, then you may wish to uncheck the Use View Settings option that is described in the following section.






Brightens or darkens the environment map in a way that imitates changing the exposure setting on a camera.


Modifies the relative brightness of different parts of the environment map using a gamma curve.  This property can help simulate the response to light that different cameras and display devices have.


Rotates the environment map as if a person observing the environment turned his head right or left.


Rotates the environment map as if a person observing it looked up or down.


Rotates the environment map as if a person observing it tilted his head sideways.




Export Map Section


This section allows you to export the rendered environment map as an image.





"Standard..." button

Environment maps are high dynamic range images, which means that they may contain color values that exceed the standard 0 to 255 range.  In other words, areas of an environment map that appear to be solid white may actually contain details that are too bright to be displayed.  Clicking this button will export the environment map using a traditional image format, which means that the high dynamic range of the environment map will be lost.

"HDRI..." button

As noted above, environment maps may contain information that falls beyond the range supported by standard image formats.  Clicking this button will export the environment map using a High Dynamic Range Image (HDRI) format that is able to encode this information.  HDRI files are often significantly larger than standard image files, so you may wish to verify that your intended use will benefit from HDRI before selecting one of these formats.

Use View Settings

Specifies whether any adjustments made in the View Settings section above will be reflected in the exported image.




Result Section


This section shows the rendered result.  The buttons along the top of this section will zoom the preview.






Sets the image to its actual size so that each of the image's pixels corresponds to one screen pixel.


Zooms the image in or out so that it is as large as possible while still fitting within the view area.


Zooms in.  The image will appear larger.


Zooms out.  The image will appear smaller.



If the image is sufficiently large that parts of it fall outside of the view area, you can drag the image in order to scroll it.
