Blender add-on: Accurate Region Border

Blender add-on for setting render region border with exact values and easily manage it.

The “Accurate Region Border” add-on helps you to set the exact position and size of the render region border.

Add-on functionality:

To set the render border coordinates and sizes simply type the required values ​​to fields on the add-on panel.

The position of the render border is set by the coordinates of its left-upper corner. The render border size can be set in two modes – by the coordinates of its right-lower corner or by its width and height.

If the render border was activated by the keyboard (ctrl+b), to get its coordinates from the viewport, just press the “Sync” button on the add-on panel.

In each separate 3D-viewport area the render border is controlled by the values ​​from the separate add-on panel.

The coordinate values of the render border can be animated. To render the frames sequence with the animated render border coordinates press the “Render Animation” button on the add-on panel.

Only the camera-view render border can be animated.
