modo saves images in various ways, depending on how the image is generated and/or applied. Understanding the individual instances will ensure that no image goes unsaved, or is inadvertently saved either.

Saving Rendered Images

When rendering by way of the 'Render' command (menu bar option 'Render > Render' or by pressing 'F9') modo obviously renders the image, but once finished, the image is in a limbo state within the Render Display window. It is cached to disk temporarily for you to preview; this is useful for the iterative process of adjusting scenes. However, the image itself is not truly saved until the user specifically tells modo to do so using either of the two options for saving; the 'Save Image' and 'Save Layered Image' functions. Each time the 'Render' command is invoked, modo will calculate all render outputs simultaneously. They appear in the layer list of the Render Display, highlighted here.

Render Display Window

When using the 'Save Image' option, the currently selected (i.e. visible) render output will be saved. Pressing the button opens an operating system appropriate dialog window, allowing users to specify a location and filename for the image, and most importantly a format. modo supports a wide variety of bitmap image formats, each with their own benefits and limitations. By itself, modo support the following formats--

Format Name Extension Bit Depth
per channel
Compressed Type
Flexible Precision Image Format .FLX 32 bit Yes Lossless
Targa .TGA 8 bit + Alpha No  
Windows BMP .BMP 8 bit + Alpha No  
Radiance High Dynamic Range .HDR HDR Yes Lossless
JPEG 2000 .JP2 8 bit Yes Lossy
JPEG 2000 16-bit .JP2 16 bit Yes Lossy
JPEG 2000 16-bit Lossless .JP2 16 bit Yes Lossless
JPEG .JPG 8 bit Yes Lossy
Portable Network Graphic .PNG 8 bit + Alpha Yes Lossless
Portable Network Graphic 16 bit .PNG 16 bit + Alpha Yes Lossless
PSD (Photoshop Document) .PSD 8 bit No  
SGI RGB .SGI 8 bit No  
Tagged Image File Format .TIF 8 bit + Alpha Yes Lossless
16-Bit TIF .TIF 16 bit + Alpha Yes Lossless
16-Bit Uncompressed TIF .TIF 16 bit + Alpha No  
Open EXR .EXR HDR Yes Lossless

 

Render Display

When using the 'Save Layered Image' option, modo will save all available Render Outputs simultaneously, when pressed an operating system appropriate dialog window opens allowing users to specify a location and filename for the image(s), and a format as well. The following options are available--

Format Name Extension Bit Depth
per channel
Compressed Type
Layered PSD .PSD 8 bit No  
Multi-File PNG* .PNG 8 bit Yes Lossless
Multi-File PNG 16 bit* .PNG 16 bit Yes Lossless
Layered Open EXR .EXR HDR Yes Lossless
*Multi-File PNG saves all outputs with appropriate output name appended to each

 

Saving Animation Sequences

Saving an entire animation of still images individually would be pretty tedious, thankfully, there are several options for saving sequences automatically. Utilizing the 'Render Animation' command from the menu bar (''Render > Render Animation') presents three options for saving-- 'Image Sequence', 'Movie' and 'Layered Images'. Choosing 'Image Sequence' is highly recommended; this allows users to render entire animations of individual frames that can be assembled in a video editing application that accepts them. It also provides an easy means of updating frames without having to re-render the entire sequence, should the need arise (additionally, it offers the ability to recover from system crashes, allowing user to pick up where the system left off, without the fear of a corrupted video file). When invoked, an operating system appropriate dialog window will open allowing the users to, again, specify the File Name, Location and File Format. The 'Image Sequence' and 'Layered Images' options offer identical file format options as their respective commands from the Render Display window (listed above). The 'Movie' option provides choices specific to the users platform and operating system.

Render Outputs--

Individually, file location, name and format can also be specified within each Render Output. This is useful as it is saved within the file and is therefore portable and persistent across modo sessions. modo only utilizes the 'Output Filename' option when the 'Render Animation' command is invoked. Once specified, and the command initiated, a pop-up requestor will prompt the user if they wish to use the filename as specified in the render output. Select 'Yes' to use it, and 'No' to specify an alternate name.

IMPORTANT: Users should note that pressing 'F9' or utilizing any of the other various render commands will not automatically save images as specified in a 'Render Output'. Only the 'Render Animation' command utilizes this option.

 

Saving User Created Images

modo offers users the ability to create bitmapped images directly in modo eliminating the need for an external image editing application. Within nearly every image loader and image browser viewport, users are offered options to create a 'New Image' or 'Image Sequence' (Alternatively, these commands are also available in the menu bar under the 'File' option). When utilizing either command, a operating system specific dialog will open prompting users to choose a filename, location and format. Once specified, another dialog opens allowing users to choose various options related to the image.

New Still Dialogue

Once the user clicks 'OK' or presses 'Return', the image is saved to disc. It's important for users to understand that this file is not imbedded into the modo file itself, but acts like any other imported image remaining linked to the saved external file as specified. This newly created image is effectively a blank canvas for users to use for painting, sculpting and baking (or any combination thereof). The image appears within the images viewport and is immediately available as a texture layer for placement anywhere within the shader tree. However (!!!) any modification made to the image once created will not be saved unless the user specifically requests modo to do so. FIles can be saved several ways. First, by way of RMB-clicking the image in the image viewer palette, and choosing either the 'Save' or 'Save As' command. Secondly, by way of the menu bar commands 'File > Save Image' or 'File > Save Image As'. In the case of scenes with multiple images, the highlighted or selected image in the image viewer palette is the image saved when utilizing either command. Lastly, if any modifications have occurred to images present in modo when exiting the application, users will be prompted if they wish to 'Save' the changes, overwriting the files previous saved state.

modo has the ability to save scenes rendered in stereo into several different formats. To render a scene in stereo, users must first enable the 'Stereoscopic' option in the Camera's properties viewport under the 'Camera Effects' subtab. Adjustments can also be made to the 'Interoccular Distance' and the 'Convergence Distance' if necessary. Once enabled, each time a render command is invoked, two images will be rendered representing the left and right eye views, filling two slots of the Image Cache. Users can simply save these two images separately (as specified above) for compositing in an external application. In order to save still images as a combined stereo image, users will need to use the 'Render Animation' command.
The 'Render Animation' command provides several options for saving images. For composed stereo images, users must choose the 'Movie' format as the 'Save As' type. Users may also prefer to set the scene range to the same values to avoid rendering out additional unnecessary frames. Clicking 'OK' opens the OS specific dialog, where there are several options for saving formats. Choose either the 'Anaglyph Stills' or 'Side By Side Stereo' PNG options. Once the 'Save' button is clicked, modo will render the stereo image and save it to disc. Searching on-line for stereo viewers will provide options for users to find the additional equipment necessary to view the rendered stereo result. modo provides a number of options to adjust the composing of the stereo images in the 'Preferences' section of the documentation.

TIP: Users often ask which is the best format to save in. Unfortunately, there is no one correct answer as it is highly dependant on the intended use; particular workflows impose specific requirements. Visual effects work is enhanced by the additional information afforded by HDRI formats such as HDR and openEXR, but these formats also require the greatest amount of storage space. Advertising and visualization are often further edited in imaging applications such as Photoshop. The layered PSD format could be a good choice, but the 16 bit flavors of TIF and PNG can afford additional editing leeway with their extended bit depth. Any of the compressed formats will help reduce the amount of disc space necessary, especially when storing long image sequences, but lossy formats may also introduce compression artifacts that can reduce quality of the final deliverable. For best results, users should thoroughly test their chosen format to ensure they receive the intended outcome.

When render animations and saving its frames as image sequence, one only needs to specify the main name, Modo will automatically append a frame number. If one names the image sequence as "animation", Modo will name each frame as "animation0001", "animation0002", ..., so it's advisable to name it as "animation_", then Modo will name each frame as "animation_0001", "animation_0002,..., this workflow will save time a later stage when renaming the frames!

Would like to see Layered 16 bit TIF support. Thanks!

Please help on how can a L and R image from stereoscopic render can be saved separatedly? (imageR, imageL)
Camera item is marked stereoscopic (both) I see them on the renderviewport (and the combined mode) but when I save layered passes as image, only saves imageL.
