Blender add-on allows setting accurate coordinates for render border.
After add-on installation in T-bar additional “ARB” tab appears. On this tab, it’s possible to set accurate values for left-top and right-bottom render border corners coordinates in pixels. Coordinates establish relative to the render size (Properties — Render — Dimensions — Resolution). After pressing the “Set Accurate Render Border” button render border determines in accordance with the entered values.
Add-on is free and open-source. If you want to support it – you can buy the add-on for a convenient price, or set the price to 0 to download it for free.
One of the essential conditions of comfortable work is the convenience and speed of accessing add-ons functional. It is not enough to write an add-on and register it in Blender API system. Be sure to give the easy call add-on functions ability to the user. So, any add-on should determine a place to put interface buttons that provide access to its functionality.
All available Blender user interface located on panels. Three panels are the most used: T-bar – opens/hides by pressing the t keyboard button, N-bar – opens/hides by pressing the n button, and the Properties panel – called in the main menu of any window, typed it as Properties.
Blender API allows defining users panels to place add-on functional buttons on any of these three main panels.
