# Render-To-Print-Blender-Addon
|
||||
|
||||
Render to print for blender 2.9+
|
||||
|
||||
Script used to set the size of the render for a print.
|
||||
You can set the size in centimeters, change the DPI and, optionally, set the pixel size to obtain the actual size.
|
||||
You can choose the size of the render from various print standard size.
