How to move and snap 3D objects in a 3D scene

Godot Version

4.3

Question

Are there any snapping tools, options or plugins that help with snapping 3D objects to parts of other 3D objects in a 3D scene?

The only option I have found for snapping in Godot 4 is to snap to grid.

Thanks

Perhaps this could be useful

Use collision detection ray to reposition an object already in the scene

Thanks @tomcat

I’m really looking for snapping functionality you get in 3D apps like Blender, Maya and Unity where you can drag a model and snap its position to a part of another model.

In Unity I think you hold the ‘V’ key then select and drag a model by a vertex for snapping.

Here’s a video -

The feature is really useful and handy. Perhaps it will be further developed.

Thanks @alex2782

I can’t get the Extra Snaps to work - not sure if it’s because I’m on a Mac or not using the right nodes.

Snappy works just like vertex snapping in Unity with the ‘v’ key.

I’ve now also tried “Extra Snaps” on a Mac. I think there is a conflict with the shortcut Cmd + W

details

While pressing Ctrl / Cmd + W, move your cursor along a surface to snap the selected object to the surface

In Godot 4.3 Cmd + W = Close

It was possible to change the keyboard shortcut to “V” in a script. My tests were correct so far, there are a lot of setting options.

Thanks @alex2782 - that works well.

I started learning Godot again recently. This time around I discovered Godot has addons like Blender. And you have shown me they are scripts that can be edited.

This is great. Thank you.

very easy:

(soon) Shift + G in the Version 4.4 (dev)

YES!

I will check this one out. Thanks!

I saw this in another video recently (posted below).

Have Snappy and Extra Snaps been removed from the Godot Asset Library?

EDIT:
It’s okay, I found them.

I couldn’t see them in the Godot opening screen Asset Library but see them in the game’s Asset Library for an open project

Does anyone have any problems with the Snappy addon in Godot 4.3? I have it installed and enabled but no vertices show for snapping when I use the ‘V’ key.

EDIT:
Snappy is working with imported meshes but not working with CSG Shapes?
