Nadir Patch
In: 3D View > HDRI Tools
Description
This node provides functionality to patch over the central ground point (nadir) of a spherically mapped image. It can be used to hide or “clone out” an ugly nadir, or visible camera or tripod. It works like a Clone Patch, but with adjustments for spherically mapped images. The user selects a point elsewhere in the image, that is the cloned and blended in at the nadir. No other external inputs are required other than a single HDRI to process, but an external mask can be used as alpha for the patch effect.
effect can be quickly checked and validated with Nadir Extract.

Input Color Input
Mask Input Grayscale Input
Optional mask slot used for masking the patch. Function like an alpha.
