"This tool helps to compositing directly in the scene."

3D Viewport Mask or Mask:

• This tool creates a mask based on the Curve or Mesh.

• It allows compositing directly inside the 3D Viewport.

• It has various mask settings for further control.

• Can be stacked for multi-mask layers.

Plane Sudivisions: The plane can have a different aspect ratio while importing an image as a plane. Thus using the Subdivision modifier does not give uniform grid divisions. This tool allows subdividing the plane by considering the aspect ratio, producing uniform  grid divisions, which are essential for the 3D Viewport Mask.

A video demo is also available on my YouTube channel: 3D Singh VFX
