Blender has a very convenient ability to set the desired values through mathematical expressions. If we don’t know the exact value, instead of manually calculating it, we can simply enter an expression that will calculate the desired value.

To get a list of vertices from the vertex group by its name we can use the following code:
|
1 2 |
[vert for vert in bpy.context.object.data.vertices if bpy.context.object.vertex_groups['vertex_group_name'].index in [i.group for i in vert.groups]] # [bpy.data.meshes['Cube'].vertices[0], bpy.data.meshes['Cube'].vertices[1], ... |
Blender Outliner supports a sequential selection of a number of objects or collections – hold the left mouse button and move the cursor in a required direction.
Blender supports opening projects by drag and drop. You can hold the *.blend file with the mouse, drag it to the Blender window and choose: open the entire file (replacing the currently open project), add or link objects from the dragged file to the current project.
The “Bloom” effect in the EEVEE rendering engine looks very impressive but does not visible when rendering on a transparent background.
But this can be fixed.
To render only the shadow of the object in Blender Eevee:
To increase the speed and convenience of working with the “Pie Menu” in Blender you can use its “autoclick” option. To use it press the desired “Pie Menu” call keys, don’t release them, move the mouse cursor in the direction of the desired item, and only then release the buttons on the keyboard. You don’t need to click on a menu item, the choice is made automatically.
2.79: selecting with the right mouse button
2.80: left-click selection
2.79: called by pressing the “t” key
2.80: it’s gone, functions moved to the main menu and to the context right-click menu
2.79: “a” – select all and deselect all
2.80: “a” – select all, “a – a” or “alt+a” – deselect all

There are three mathematical constants in Blender which you can enter in any field and immediately get its numeric value.
They are:
In Blender 2.8, the displacement node in Cycles render-engine was changed from scalar to vector. If you simply connect a black and white height map to the Displace input of the material output node, like in Blender 2.7, it will not give the desired result.
To make the correct node displacement in Blender 2.8 add “CombineXYZ” and “VectorDisplacement” nodes to the material node tree. Connect the height map to the “Y” input of the “CombineXYZ” node and its “Vector” output to the “Vector” input of the “VectorDisplacement” node. After that, connect the “Displacement” output of the “VectorDisplacement” node to the “Displacement” input of the material output node.
