Chapter 67: Render Preferences

Parameter Description
Preview Options

Enable Blur: Renders blur effects derived from the Blur-Directional Module, Blur-Radial Module, and the Blur-Variable Module in the Render View window.

Enable Line Texture: Renders line texture in the Render View.

Enable Focus: Renders focus effects from the Focus-Apply and Focus-Set modules.

Preview Images

Cache Size in RAM (in Mb): Cache size in RAM for intermediate preview images (Mb).

Cache Path and Capacity in MB: If this field is left empty, Harmony's temporary directory will be used to off-load intermediate images. There is no disk usage limit for the temporary directory.

When you specify a folder, you must type in the capacity (in MB) inside the path. Use the following method: path;capacity in MB;
ex: C:\user\tmp_image_folder;2000;

Note: The specified folder must already exist. If there is an error in the path, Harmony’s temporary directory will be used. You can also specify a RAM drive in the path.

Multi Threading

The Multi Threading preference lets you specify the level of parallel processing done during the final image calculation (soft-rendering). Allowing parallel processing speeds up the soft-render process.

Number of Rendering Threads: Lets you specify the number of parallel processes during the soft-render process. A value of 1 disables the multi threading process because it specifies that only one rendering thread will be used during the process. The maximum number of threads value is 64. The recommended starting value is 2 threads per CPU core, meaning that if you are using a 2 Quad Core CPU, the preferences should initially be set to 16 threads.

  Enable Graphic Card Acceleration: Optimizes the rendering blurs by using the GPU's acceleration capabilities. This option is on by default. Not all cards support this acceleration.
