To copy an object you have to be in Object mode, right click on the object that you want to copy and the press Shift + D to duplicate it first. The duplicate will be in grab mode so right click to get out of grab mode without changing its location. The object will still be selected but if it isn't, you can look in the Outliner for it. It will have the ...

Disable lock layers to scene in 3D view > Header to use local layers: Then each 3D view can have it's own visible layers.

Layers Layers are a way of splitting up and organizing the objects in your scene. In the 3D viewport. You can select the currently visible layers in the footer of the 3D view or under properties panel > render layers tab > layer rollout > scene layer selector. (With any layer selector you can hold down Shift to select multiple layers.) You can see ...

For a better scene organization I'd suggest use the layer management addon, which is shipped with blender by default: In addition, the Outliner provides some functionality to display the desired data types like Groups, Same Objects, Selected Objects etc.:

How Metaballs Works A metaball object can contain multiple metaballs which you can add in the edit mode of the object, all metaballs in the same object tend to be polygonized together, that is, they combine forming a single mesh. Moreover, if another metaball object that possibly contain multiple metaballs have the same "predot" name (Object, Object.001, ...

As far as I know, you cannot do such modifications in the layers table of the 3d window header. Solution: Enable the Layer Name addon. You can then change the layers names. You'll find the Layer Managment tab in the Tool Shelf (T).

Shift + LMB on the layer boxes in the Relations section of Properties->Object. Or in 3d view hit M in Object mode, and Shift + LMB on the layer boxes there

#add to layer 2 first - needs to be on at least one layer profile_object.layers[1] = True #wipe other layers for i in range(20): profile_object.layers[i] = (i == 1)

No. A Scene object only contains exactly 20 layers, no more, no less. But if you mean render layers, the upper limit is 32768.

Blender 2.8 re-implements the scene layer system, as it had limitations. How it now works is explained here: Layers Manual and here: Blender Dev blog. The scene layers are gone and their functionality was implemented in Collections (=groups) and View Layers. Instead of sorting objects onto different scene layers, you can sort them into different ...

Select the objects that you want to move and press M, then select the layer you want to move them to. You can also have an object in several layers, for that after pressing M, Shift + LMB select the layers.

There is no special property or method to retrieve all objects on a certain layer in Blender. There is a context member visible_objects, but multiple properties affect it (visibility of object, visibility of layer). Thus, you should use a plain Python list comprehension: objects_on_2nd_layer = [ob for ob in bpy.context.scene.objects if ob.layers[1]]

You can press ` which is usually found immediately to the left of the 1 and directly above TAB. This will make every layer visible so now using a will function as you would like it to. Or you could just select something using a mouse/pen click, this will also release any hidden layer selections.

Select the suspicious layer. In the Outliner, set the Display Mode to Visible Layers: If there's anything there – hidden or not – you'll see it there. If nothing appears, please upload your .blend file for further diagnosis.

Cycles: Set the renderlayer with the reflective object to Exclude layer one: Now objects on layer 1 will not have any affect on layer 2. Example .blend Blender Internal: In BI this is more complicated, because it appears to be impossible to separate reflections into separate layers with BI. In other words, you can either reflect every object in the ...

"The best" is certainly opinion based and bound to personal preference, there are definitely different approaches, workarounds and valid alternatives. Working daily in archviz in Blender however I end up exclusively using Groups for organizational purposes instead. Haven't really touched Blender's Bit Layers for scene management in quite some time, except ...

Select them all. Without knowing the layout of your scene, it's hard to say what the best way to do this is. Manual: Try pressing ` (the key below Esc, at least on qwerty keyboards) to set all layers visible. Then use Border select (B) or circle select (C) in wireframe mode to select all the shards (you may also want to try hiding (H) any other objects ...

In render tab, film options just click "transparent" to get alpha

the outliner does show it, and it corresponds with bpy.context.scene.active_layer

As indicated by the tooltip when hovering the mouse pointer over it, the Render Layer Samples setting allows you to override the Number of samples used. Setting it to 0 (the default) tells Blender to use whatever is the default for the scene (ie, the number of samples set in the Samples panel of the Render properties). Setting it to a non-zero value will use ...

You can animate layer's Disable or Enable using I. Set keyfrimes like you set keyframes for object visibility: For example, for start frame on the 20th and end on the 35th, you should set 3 keyframes: off - anywhere before 20 frame, on - on the 20th frame, off - on the 35th frame

small utility function I use: put_on_layers = lambda x: tuple((i in x) for i in range(20)) obj.layers[:] = put_on_layers({2,6,5,11}) {2,6,5,11} is a set, can be 1 or more values, starting from 0 ending at 19.

On a localized keyboard this key is often only accessible with a modifier like Shift. If it doesn't work as described by Marc check the settings in the User Preferences: Note that this key can be configured separately for the different modes. In other modes than 3D-View it defaults to Ctrl-'.

While the 3DView is fixed at 20 layers, you can get similar functionality using groups. By having the outliner list groups you can show/hide all objects in a group at the one time. This method hides objects, so is basically a shortcut to hide/unhide multiple objects without having to manually select each one. The catch with groups is that while an object on ...

When you click append, select all your objects then in the lower left hand corner, there should be an option panel. Untick the Active Layer option.

You hold Shift in order to multi-select many objects. After you selected all your objects, you can move them to a new layer by pressing M to select the layer you want them to be in. Or use M folowed by the layer number, for example: M3 will move the selected objects to layer 3

You might be able to accomplish the effect you want using Compositing and Render Layers. https://www.blender.org/manual/render/post_process/layers.html Put the red sphere on one layer and the blue sphere on another layer. Make sure the red layer is transparent ( Can Blender render pngs with the background transparent? ) Some of the compositor nodes you ...

Try selecting the object and pressing M to move between layers. If all the layers are selected in the dialog which subsequently appears, press 1 (or click on the first layer in the dialog with LMB) to move the object to just that layer.
