Blender is selecting vertices from behind WITHOUT XRAY

Support Modeling
#1

While doing retopology, I came across a super irritating problem of selecting vertices. Every time I use box, lasso, circle select, I find myself selecting not only the vertices from the front but also vertices from behind, which I cannot even see, (but they happen to align with the front ones) and don’t care to see, because I am not using x-ray for this exact purpose. This issue slows down the workflow by a lot . Tested on 2.8, 2.83, and different computers.

Please, which tickbox to click to solve this problem?

top right corner , turn off X-ray, this way background vertices disappear and can’t be selected.

But, i already have xray disabled.

#4

hmm , its not supposed to happen, maybe i’m missing something else.

#5

Can you try with other objects, etc. or give link to scene file ?

Welcome to the community, @Gorlomi! Have you tried turning on/off the OpenGL Depth Picking option in the Preferences:

Thank you!
Yes, i tried. No luck.

I was trying to reproduce with simple scene, and noticed something.
We all know that we can select vertices from behind. Well, i still can, even if there is another mesh inside, that is clearly blocking the view of vertices on the back.
I guess it is rather a feature, but i would like to disable it! :grinning:

So you’re saying you have an outer mesh and an inner mesh, and you are able to select through the inner mesh to select vertices on the back of the outer mesh?

#10

Yes, exactly.

Are you using any addons or modifiers? A screenshot would be great - a shared .blend file would be great, too! You can use https://pasteall.org/pic/ to share images to link here and https://pasteall.org/blend/ to share .blends here.

#12

No Modifiers, except subdivision, which I applied.
No Addons, except from those that have been added automatically by blender.

Here I proceed to select 3 vertices. And I end up with 14 selected, including vertices from the back.

Cant unfortunately add more than 1 pic at the moment.

It would be interesting if it can be reproduces by someone else, or i have 2 laptops cursed or something

#13

I can reproduce, what you’re describing. It seems like meshes, that aren’t in Edit Mode as well, are not accounted for when occluding vertices from selection. I don’t know of a setting that would change this behaviour.

I’ve been recently learning about the differences in the selection tools, and I am curious:

Does this same behavior exists with the lasso and circle select tools?

Does this also happen for other selection modes (edge or face)?

#15

Ok… this is normal.

#16

Yes, it is also reproducible with lasso and circle selection tools.
As well as faces and edges.

#17

But it is not what you would want. If i do not see a vertex, i dont want to select it, obviously

#18

You should post this as a feature request on right-click select

If you open an entry for the request, you share that image with the spheres and explanations you posted above and with a title similar to this: When selecting, respect occlusion by other objects in Edit mode

So, to make it a little less confusing than this thread.

Okay, very weird question: Now that 2.8x allows multiple objects in Edit Mode, if you have both your inner and outer object in Edit Mode when you do your selection, does Blender respect occlusion?
