I'm wanting to use the patch tool the same way I've done in Photoshop to remove the nadir hole in 360 equirec images but it's leaving sort of a halo effect in the the patched area. Is this the same problem you're addressing? If not is there a way of changing the opacity or something of the sort? One of the things that the patch tool an PS does very well is colour blending and I just want to be sure I can get the same results. If so, this may be the turning point for me no longer using Adobe.
