Info:
For 3ds Max 2022 added

FloorGenerator is a plugin for 3ds Max which generates floor objects consisting of individual boards which can easily be textured using MultiTexture. It?s a great tool if you?re doing architecture visualization and need to make floors that are NOT going to tile and that you can see up close without any pixilation.

Copy the .dlt file that correspond to your version of 3ds Max to the
/plugins/ folder located in the root folder of your 3ds Max install.
