Those are the areas that are occluded in the input images. If you look at the bushes, you can see that the front is clean while the back is a mess. Probably the starting position could be chosen a bit better.

This raises the question, do any of these projects have workflows for combining images taken from different positions? Or does that just work out of the box? (I have no machines atm with anything better than 10yo eGPUs ;~<)

The path to left and right is occluded? By what?

By not taking photos of it... what else? The data wasn't there, so it couldn't be generated

Actually, this might be a lack of understanding, look up what gaussian splatting is.

That's not occlusion.
