For 32-bit systems, this cannot exceed the maximum amount of addressable RAM, apart from that needed by the system itself, typically around 3GB. You can increase this value to render geometry-intensive scenes, such as those using fur and subdivision surfaces with Micro Poly Displacement. When the amount of geometry exceeds this value, an error message is displayed. This value, set as GB (Gigabytes or 1 billion bytes) determines the maximum amount of system RAM Modo uses to parse scene geometry for rendering. Generally speaking, the best performance is obtained when the number of threads equals the number of total cores, virtual or otherwise. However, there is a point of diminishing returns, where overhead of thread management outweighs benefits of the extra threads. The greater the number of threads, the faster scenes render. When Automatic Render Threads is disabled, you can manually set the number of render threads, which reflect Modo's ability to simultaneously calculate rendering information, each calculation taking place as its own thread. When enabled, Modo determines the number of threads automatically based on the number of CPU cores and other factors, such as Hyper-Threading support.
There are three options: None disables the cache functionality, Fast stores a limited data structure that allows for faster display, although less accurate, and Full stores the entire VDB file in memory for faster access, but requires the most RAM.ĭefines the amount of dedicated RAM to be used for the stored data. Note: Modo normally initializes scene files if OCIO color configurations are not stored correctly in the file.įully optional, but can be used to speed up the display of VDB sequences. Consequently, it may be desirable not to use Modo's default color correction on loading the files as they may already have been corrected using an alternative method.
When this option is enabled, the Default View Colorspace option adjusts the display of the Color Picker viewport pop-ups and windows to match the colors of the Render display.Īpply Color Correction Profile to Legacy LXO filesĮnable this to apply the default color correction profile to pre- Modo 801. When this option is enabled, the Default View Colorspace option adjusts the display of individual color input fields in the Properties form to match the colors of the Render display. These options control the colormapping assigned to user interface elements, including the Color Picker Viewport, Color Swatches, the Render Display window and the interactive Preview Viewport. It defines the colormapping assigned to UI elements, including the Properties Image Still tab Color > Colorspace. This option allows you to set a default colorspace to use when displaying images. You can also designate colorspace profiles individually on the Image Map item in the Image Still subtab. These options designate the scene-default profile assigned when reading and writing the associated bit depth of image for any items that have their colorspace control set to Default. You can also designate a config for individual scenes manually in the Scene Item. Each type contains a different set of profiles.
Each separate configuration controls which color spaces are available for use by items in the scene. This option controls the default configuration type for new scenes. The Rendering preferences contains all settings that determine the rendering behavior of Modo.
