P: Lens Blur brush refinements aren't copied by Sync Settings and Copy/Paste Settings

When I make a virtual copy of test1.jpg, and then Sync Settings from test1.jpg to the virtual copy, the Lens Blur is copied exactly.  Ditto if I use Copy/Paste.

For all of the AI commands (masking, lens blur, generative remove), when you copy their settings from the source photo to a virtual copy of that source photo, LR doesn't recompute the AI results -- it just blindly copies all the internal settings without recomputing. That works because the virtual copy pixels are exactly the same as the master photo's pixels.

So that probably accounts for why syncing lens blur from the master photo to its virtual copy brings along the brush refinements too.  

It's when you sync lens blur to a different photo (different internal UUIDs), that LR decides it needs to recompute the AI results, and that recomputation is failing to include the brush refinements for some reason.

1. First up, yes, I was in error.

Ah, I can now see where I was overlooking this issue. Shame on me, I concentrated on the sliders, not the visible result. And in hindsight it is obviously wrong.

So, that brings up a followup. In the second image, in the Lens Blur panel, if you click on and off the visibility "eyeball" you can cycle though on and off, thereby helping to see what has occurred or not. After doing that I have no idea why I overlooked that before.

So lens blur has occurred, but the result is very different.

2. Second up an additional oddity.

On the initial sync from the first image to the second, in the lens blur panel, notice the grayed out RESET within the Brush Refinement section:

3. And a different twist on the Virtual copy.

So I decided to create the virtual copy. But instead of manually setting the lens blur, I choose to see what might be different if I approached the SYNC differently. That is instead of using /Settings/Sync Settings/, I used /Settings/Copy Settings/, then /Settings/Paste settings/

Dang if the result was better. It matched. (Or so it currently looks to my eyes)

4. Aggggh.

But if I revert the second back to before the sync, and attempt /Settings/Copy Settings/, then /Settings/Paste settings/, the same problem appears again. So works on virtual but not different images.

BUG

Your screenshots show the bug:

1.png shows test1.jpg with default Lens Blur settings applied, Blur Amount = 100  plus the Blur brush applied everywhere except around the lettering on the cup:

2.png shows test2.jpg with no Lens Blur settings applied yet:

5.png shows the result of syncing Lens Blur from test1.jpg to test2.jpg. The background has been blurred moderately (compared to 2.png), but the foreground remains sharp, unlike in 1.png / test1.jpg:

If you make a virtual copy of test2.jpg, reset it, and apply the default Lens Blur settings, Blur Amount = 100. but no Blur brush, you'll see that test2.jpg (after sync) and the virtual copy look identical.

but the brush refinements are not.

What were the brush refinements? Perhaps I am overlooking them.

At any rate, On my Windows RIG (sorry, I no longer have a MAC rig to test with)

Does not look like I can repeat. Or I am confused (it happens)
