Reference Display options (image view)

Zooming in and out will scale or shrink the images only by integer amounts (2x, 3x, 4x, etc.).

Generates mipmaps on demand when the image is zoomed more than 3x. This may cause a slight delay during scaling as Houdini generates the mipmap.

Brings MPlay to the front when a render begins.

When this option is turned on, rendering to MPlay will copy the previous image onto the new image as a background so that slight changes can be compared as the new image renders.

Images with pixel aspects not equal to one are stretched (>1) or squashed (<1) to approximate the image on hardware devices with non-square pixels. If this option is turned on, a simple hardware scale is used. If off, a slower but more accurate software filter is applied.

Click to open a window that lets you control various settings that help adapt the display to different video card hardware capabilities.

Split views/single view.

When on, adds images to viewports horizontally first, when the viewport has multiple rows/columns. When off, adds images vertically first.

Keeps all viewports visible, even if whole rows or columns of viewports are empty. When off, the view dynamically adapts the viewport layout to the number of images available.

Specifies the initial layout of viewports, from 1×1 to 4×4.

Controls the amount of information shown in viewports. Minimal shows only the name, Verbose shows all information available.

See image guide file.

Allows you to choose the display mode of stereo images in MPlay. You can choose between Anaglyph, Horizontal Interlace, or Horizontal Interlace (Reverse).

Choose the file to use as the background image.

Manually specify a resolution to use for the background image instead of using the natural size of the image.

Most rendered images are pre-multiplied, which means that the color has already been multiplied by the alpha plane.

However, if you place an arbitrary alpha plane without running it through a Premultiply COP, the resulting image is not pre-multiplied, and you must turn off this option or your transparency will be wrong.

For example: place a File COP, append a Shape COP and have it replace the Alpha plane with a star shape - then enable transparency. You’ll need to turn off Foreground Images are Premultiplied to see the proper image.

Background color of the image viewer, default is black. Click the color swatch to display a color picker.

Choose a LUT file to apply to the images.

When inspecting, run raw values of the image backwards through the LUT file to produce the original values (Cineon values).

The default gamma applied to all images. You can interactively change gamma using the color correction controls.

The names of planes the viewer should gamma correct. Normally, this is just the color plane (C).

Whether to apply the gamma correction to the viewport background color and the background image.

If on, the brightness/contrast (and black/white) controls in the correction toolbar are applied to the color before the LUT and Gamma. Otherwise, they are applied afterwards.

Anti-aliases handle and guide lines.

Makes handle and guide lines slightly transparent.

The default color for handles and guide lines. Click the color swatch to show a color picker.

The size of the handle’s clickable area, in pixels. Larger values make the handles easier to grab.

Current Node(s), Current/Display, Current Node.

Limits the amount of cached image data to the Image cache size.

Dictates how much memory MPlay will use to cache images for playback in Mb.

Flushes the image cache, freeing all memory except the memory used by the currently displayed image(s).
