Install the plugin

This plugin is not compatible with Blender > 2.79.

  1. Download and install Blender 2.79b.

http://download.blender.org/release/Blender2.79/

  1. Clone this repository in the addons folder of blender 2.79 :
git clone https://github.com/ABelliqueux/blender_io_export_psx_mesh.git

You'll need to have pngquant and img2tim utilities installed and in your path for PNG to TIM conversion.
Windows executables are provided for convenience in this repo.
For users with Imagemagick installed, there is an option when exporting to use that instead of pngquant.

On Linux : ~/.config/blender/2.79/scripts/addons
On macOS : ./Blender.app/Contents/Resources/2.79/addons
On Windows : %USERPROFILE%\AppData\Roaming\Blender Foundation\Blender\2.93\

Install the 3D engine

Head over to the 3dcam repo and follow the setup instructions there.
