Render Mode
This pop-up defines what quality and features are enabled when Form renders a frame. Here are the settings:
Motion Preview
This mode renders each particle as a quick and dirty point. This mode is useful for previsualization.
Full Render
Full-quality render, but explicitly excludes Depth of Field.
Full Render + DOF Square (AE)
Full-quality render with Depth of Field. For custom particles, the DOF blur used is similar to AE's own, a squarish look which, while faster, means less visual quality.
Full Render + DOF Smooth
Full-quality render with Depth of Field. For custom particles, the DOF blur used is smooth similar to a gaussian blur, and will produce better results than the After Effects DOF. This option will increase rendering time.
NOTE: To enable DOF, both the Render Mode pop-up must be set properly AND the Comp Camera's DOF switch in the After Effects camera layer must be enabled.
