Vertex snapping does not work - Unity can't "find" vertices

Unity Engine

Hello,

The vertex snapping feature in Unity seems to work great. (select object in scene view, press W for move command, then press and hold V for “select vertex.” Then you click fhe vertex you want and drag it along with its mesh to snap it to another vertex.)

However about 30% of the time, Unity cannot “see” or “find” the vertex at the tip of the object you want to move. You can grab it in the middle, or on the other side, but one side is not able to be selected or “grabbed”, as if Unity thought the vertices there did not exist.

Is there a fix for this? Version 3.2 perhaps? It adds literally 30 minutes to every hour worked because you just can’t grab the pieces in the right place … very frustrating.

thanks,

Charles

I’m having the same problem, only when I add a box collider to a object, or duplicate it, I’m able to snap it.

We have a report that this sometimes happens when the scene camera is in one of the orthographic views. Does this explain the cases where snapping doesn’t work? (It’s still a bug but this information would help narrow down the problem and perhaps give you a temporary workaround.)

I’ve tried it in multiple views, but I’m getting the problem in all of them (also in perspective).

What you mentioned sounds a bit different from what I found, but I have noticed that if you drag something from the project straight into the scene it has a higher probability of not being able to use the vertex snap capability over if you drag it from project view into the hierarchy view which then always works. Maybe somewhat connected to the oddity that if you select multiple objects in the project view and drag them into the scene view only 1 ever shows up, but if you do the same into the hierarchy view they all show up.

This might be obvious, but it’s something that confused me for a moment: make sure that you’re selecting the object with the mesh and not the parent object, if the item has one. This might explain why it takes multiple clicks on the object in the scene view before vertex selection works, as the first click will probably select the containing/parent object and not the mesh object itself.
