Two-Point Perspective is a Blender add-on by Athina-Syntychaki that swaps the active camera for a copy set up with two-point perspective. It's aimed at architectural visualizations and other scenarios where minimizing distortion is essential.
The add-on converts a three-point perspective camera to a two-point one, and lets you set the target angle manually. Version 0.0.2 names the newly created camera after the original followed by the corrected angle, such as MainCam_90deg, so you can identify the corrected camera by the angle applied. The Angle Value input is greyed out when the Custom Angle checkbox is unchecked.
It runs on Blender 4.2 LTS and newer, requires no special permissions, and is released under the GNU General Public License v3.0 or later. In this catalog it's listed as free. The add-on sits at rank 323 in the Blender extensions library.
