Render Preferences

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

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

This 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 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.
