Pro Tips
- Re-render with new parameters: Click "Clear 3D" and then "Create 3D".
- Adjust 3D scale and cut-off focus: Set the frame's near plane offset to the
minimum and use 3D preview to evaluate depth scaling. Repeat until the scale is correct and
everything important is in the focus. Set the optimal value for frame's near
plane offset as a last step.
- Increase details: Decrease size of the smoothing filter (also increases noise).
