The Post Processing tab in the Render buttons has new Line Thickness options for defining unit line thickness in two different modes as follows: 1. Absolute mode: The unit line thickness is given by a user-specified number in units of pixels. The default value is 1. 2. Relative mode: The unit line thickness is scaled by the proportion of the present vertical image resolution to 480 pixels. For instance, the unit line thickness is 1 with the image height set to 480, 1.5 with 720, and 2 with 960.
