The nXt Image Editor can edit native image files (.nXtImage) produced by any of the nXt platforms. These native files retain all of the information gathered during rendering. By using the nXt Image Editor, you can:
To launch the editor
On the Flamingo nXt 5.0 menu, click More Tools > Flamingo nXt Image Editor.
Opens a file saved in nXtImage format for editing.
Saves the nXtImage file.
Saves the nXtImage file under a different name.
Saves the edited image as a bitmap image file.
Piranesi is a 3-D painting tool that creates images with a hand-painted appearance.
nXtImage files contain three additional channels that can be used as masks for advanced compositing in most bitmap editors. These channels carry alpha, distance, and material information for each pixel, encoded in a gray-scale image. Each channel can be viewed and saved to a .png file.
Saves the material channel mask.
Saves the alpha channel mask.
Saves the distance channel mask.
Saves the lighting scheme.
Displays information about the image.
Allows piecing together or overlaying segments of images rendered using the Render Farm Single Image function.
Note: Do not select the first image (000000.nXtImage) again or it will be added twice.
Adds pixel values of one layer to the other. When values are above 255 (in the case of RGB), white is displayed.
Subtracts pixel values of one layer from the other. When values are negative, black is displayed.
Subtracts the top layer from the bottom layer or the other way round, to always get a positive value. Blending with black produces no change, as values for all colors are 0. Blending with white inverts the picture.
Takes the transparent alpha-channel mask into account when blending.
Combines images rendered using the Path Tracer engine so that, for example, when you combine ten images rendered with 20 passes each becomes the equivalent of an image rendered with 200 passes.
Rendered with 20 passes (left), ten 20-pass images combined to create a 200-pass image (right).
Inserts an image rendered as a selected portion into the rendered image.
You can animate by changing the image information.
A sequence of images will be created that can be used to create an animation using software designed for this purpose.
Specifies what to display in the image.
Displays the original rendered image.
Displays the image and the alpha channel mask together.
Displays the material mask.
Displays the distance mask.
Tone mapping is the process of converting the luminance data used by nXt into RGB pixels that can be displayed or printed.
See Render Window: Brightness. Note: In nXt, the overall brightness of a scene cannot be controlled by boosting the intensity of the light sources. The automatic exposure adjustment built into the tone-mapping process will defeat this. Adjust overall scene brightness by using the Brightness control.
See Render Window: Burn.
See Render Window: Saturation.
See Render Window: Histogram.
The status fields are located at the bottom of the screen. As you move your cursor over the image, these fields display information about each pixel.
The pixel coordinate, measured from the lower left corner.
The first three fields display the RGB colors displayed in the image after tonemapping. The fourth field shows the alpha (transparency) channel, which is used for compositing.
The luminance value for each of the red, green, and blue sub-channels.
A weighted average of the luminance values stored in each pixel.
The distance of each pixel from the viewer in meters. Negative values indicate a background pixel.
The name of the material used to render the pixel.
Special Effects can be added to an image. Many of these effects use the extra information the NXTimage format stores. For instance the glare uses luminance space working on actual light values and the haze uses distance in the image.
Adds color to pixels farther from the camera. This effect can be used to add a haze or fog effect to a scene or to mask a background with color or change the background color.
Original image (left) and with haze (right).
Specifies the intensity of the haze color.
The distance from the camera where haze will start adding color to each pixel.
Pick a point on the image to specify the distance.
The distance where the haze effect is at its maximum. All pixels beyond this point have the maximum haze effect added to each pixel. Pixels between near and far have haze added in a linear fashion from the near to the far pixels.
Pick a point on the image to specify the distance.
The haze color.
Pick a point on the image to specify the color.
Since each pixel in the image contains a distance value, this can be used to blur the image between specified distances.
Original image (left) and with depth blur (right).
Specifies the amount of blur.
Specifies a distance in the image that will be in focus.
Pick a point on the image to specify the focus distance.
The distance around the Focus that is sharp. This value is in meters. All pixels within this distance will be sharp and will be ignored by the Blur filter. Pixels beyond this distance will be progressively blurred with neighboring pixels to give the illusion of depth of field.
Controls which direction the blur filter will work. The default value is Background. This means all pixels farther away from the camera than the In-Focus Zone will progressively blur.
Blur foreground (left) and background (right).
Blurs pixels farther away from the camera than the In-Focus Zone range.
Blurs pixels that are closer to the camera than the In-Focus Zone range.
Blur pixels both in front and behind the In-Focus Zone range. This is a quick way to get a depth-of-field effect. It is not as accurate as using the built-in pre-render Depth of field.
Glare affects pixels that are brighter than the Threshold in lumens by creating a halo effect on the surrounding pixels. Only the brightest pixels in the image are affected. Hold the cursor over the pixels to see glare and read the total lumens of that pixel.
Original image (left) and with glare (right).
Adjusts the amount of halo that affects the surrounding pixels.
The lower limit of the value affected by the glare filter. All pixels brighter than this value will be affected.
Pick a point on the image to specify the brightness value.
Blurs and blends the colors on the edges of the image to create a halo effect.
