Using layers, Layer Manager and Naming Layers in blender

If you have ever used photoshop or gimp then you already know the importance of layers. Like 2d designing software, 3d designing software also have the concept of layers and layer managers. In other software like Max its a bit easy to manage layers, but as you have heard blender is not so good at layer management. Even you cannot name a layer if you are using default options of blender. But the beauty of blender is addons. So don't worry I will show you the way around to do things that are not meant to be done Oooohahahahah...
Lets begin...

 

Where you should use the layers?

Lets take a scenario where you have to make a spoon with a plate and have to place the spoon in the plate then give your objects a nice steel shader and you have to take a render of it. you can do it easily without any need of layers. But think of a big scene where you have to make whole dinner set then place it on a wodden table and that table should be placed in a room under the fan and the switch of the fan should be on and light should be off as windows are open and curtains are flowing and bla and bla and bla bla bla... Now my friend I think you should use layers. The dinner set, the table, walls, switch board, fan, curtain, everything similar should be in there own layers. so if your boss asks you to use different kind of fan or to just give two renders with different kind of fans you can easily turn the layers on and off and take render easily. And apart from these scenario there are many cases where you feel the need of layers.

 

Layers in Blender

There are only 20 layers provided in blender, you cannot add or remove layers. You can turn on or off the layers, switch the layers.



In the above image you can see the icons for 20 layers. If a icon is dark grey it means this layer is active and visible. If a icon has a tiny yellow dot in it that means this layer contains some objects in it. These layer icons are also available in 'Render Layer' tab under 'Scene' label in the property window. There are also Render Layers and Mask Layers, don't confuse them with Scene Layers, we will talk about that when the time come.

 

Switching or activating multiple layers in Blender

To switch layers in blender you can do two things given bellow.

1. Click on the icon of the layer to make it active and visible and hide other layers.
2. Press the corresponding shortcut button of the layers to make it active.

The shortcut key for the first 10 layers is the buttons from 0-9 above your qwerty buttons of the keyboard and for the next 10 layers you can use Sift along with 0-9.

Keep in mind Num Pad button does not belong to layers.

To activate multiple layers you have to press Shift and then click on the layer icons to make them visible and active.

 

Moving objects from one layer to another

In blender you can easily move objects from one layer to another. Follow the steps given bellow to move objects from one layer to another.

1. Select the objects you want to move from current layer to another
2. Now press 'M' on the keyboard and click on the layer icon from the popup menu in which you want to move the objects. M is the shortcut to move selected objects from one layer to another.

 

Relating or Linking one object to multiple layers in Blender

• An object can be linked or related to multiple layers. When moving object after pressing M hold shift when choosing layer to move object. After this the object will be linked to the other layers to but the current layer will also have it.
• If you relate the object with multiple layers that doesn't make copies of the object but the data of the object will be linked, if you delete the object from one layer it will be deleted from all layers it was linked to.

 

Layer Manager in Blender

There is no inbuilt layer manager provided in the blender but they have included an Add-on for the layer management in blender. But you have to activate it to use it. To activate Layer Manager follow the steps given bellow.

1. Go to the file menu and click on 'User Preferences' or press Ctrl + Alt + U
2. In the user preferences window go to Add-ons tab.
3. Start typing layer manager in the search box and the add-on will appear.
4. Activate the add-on by turning on the check box of the add-on and then click on save user setting. and close the dialog box.

Now in the Tool Self of 3D view a new tab is added named Layers. Click on that tab and you will find your new layer manager. You can give a name to the layers, select objects of the layer by one button click, change shading mode of the objects of a layer, lock the objects of the layer etc.

Adding Text, Extruding Text and Changing Text Style in Blender

In this post we are going to learn about adding the text in blender. There are some things that you have to keep in mind. I will tell you these on the way of adding text in blender, whenever its needed. So lets get started.

Setting default font folder in Blender

If you are going to add text in your scene in blender you would probably need to change the font of the text. For changing font of the text object in blender there is no easy way. To make it a little easier you have to set user preferences in the blender, cause you cannot directly choose font for text object in blender from a drop down list. You have to choose the font from the folder. So first set the font folder from the user preferences. To change the user preferences go to file menu and then click on user preferences, or just press Ctrl + Alt + U

Now in the user preferences go to the file tab. Here you can set the default folders. Set your default font folder here by browsing to it or directly entering the path. Usually default font folder for Windows is “C:\Windows\Fonts”. After setting the path click on Save User Settings.

Adding Text in Blender

Now you are all set, just press Shift + A inside the viewport and choose Text. A text object will be added to your scene. See! that is so easy, but you don't want that, you will live happily ever after if you see your name written there instead of Text.

Editing Text in Blender

To edit the text in blender you just follow the same method as for other objects, just press Tab. Just like the other text editors a cursor will appear in the viewport with the text. You can press backspace to delete the Text and type whatever you want. After typing just press Tab to return to the object mode.

There are two more things that you probably want to know

• How to make text thick in Blender
• How to change font of Text object in Blender

You have noticed that the Text you have added has no thickness at all, its just like plane. May be this is not what you wanted. So to add thickness to the text, you have to increase the amount of extrude property of the text object. To do that just open the Text properties tab, its just right beside the Add modifiers tab. Now in the geometry section increase the amount of extrude.

Changing font of the Text in Blender

To change the font of the text go to the Font section of Text properties. Now you have to brows to the font file you want to apply. By default the Bfont is applied.

If you have already set the User Preferences and saved the default font folder then clicking on open will open the font folder.

And one more thing, You have to open all file of a font if you want to use all styles for example Font Arial's Regular in Regular, Bold in Bold, Italic in Italic etc. But its not necessary to open all file, if you want to use only Bold style then only open bold style file. By default the regular style is applied.

After opening the files you can access them from drop down list.

Now After opening text file press Tab in the viwport to go to edit mode while the text object is selected. Now select the written text by pressing Sift + Right/Left Arrow depend on the position of your text cursor.

Now choose the style from tools menu.

That's it. Now you know how to Add Text in Blender, Adding thickness to Text in blender and changing font and font style of text object in blender. And here is a tip for you, you can bevel the text object's edges by increasing the bevel amount, which is placed side by side the extrude. Bye for now and Happy Blending :)
