How to start render in the main window in Blender 2.81

Render starts in a new window in Blender 2.81 by default. And there is no more render display mode settings in the “Render” menu. These settings were moved into the “Preferences”. To configure render execution window – open the “Preferences” window, press the “Interface” button and in the “Temporary Windows” configure the “Render In” parameter as you need.

How to move cursor to vertex

To translate cursor to the desired mesh vertex execute the following code:

Attention to the multiplication order – world matrix should be left.

How to move the cursor to the active strip start/end position in Blender VSE

To move the cursor to the start position of the active strip in Blender VSE:

To move the cursor to the end position of the active strip:

 

How to get vertices from Vertex Group by its name

To get a list of vertices from the vertex group by its name we can use the following code:

 

Drag and drop files to Blender

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.

Autoclick in Pie Menu

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.

15 changes that you need to know when migrating from Blender 2.79 to Blender 2.80

  1. Object selection

2.79: selecting with the right mouse button
2.80: left-click selection

  1. T-panel

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

  1. Deselection

2.79: “a” – select all and deselect all
2.80: “a” – select all, “a – a” or “alt+a” – deselect all

Constants

There are three mathematical constants in Blender which you can enter in any field and immediately get its numeric value.

They are:

  • pi – “Pi” number = 3.1415…
  • e – Euler number = 2,7182…
  • tau – “Tau” number  = 6.2831…

Node displacement in Blender 2.8

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.

How to detect if Local View is on in 3D View window

The following command returns the 3D View areas list with enabled Local View mode:

 

Where are the icons for managing objects visibility in the Outliner window in Blender 2.8

In the latest Blender 2.80 builds, the visibility control icons are disappeared from the Outliner window.

They were not removed, they are just hidden from the interface by default. To return them to their usual place click the button with the funnel image and mark the icons you need to display.

After closing the dialog box, the icons will appear in their places.

Where did the Remove Doubles in Blender 2.80 disappear

The convenient Blender 2.7 feature to remove duplicated vertices “Remove Doubles” has disappeared from the Blender 2.80 menu. In 2.8 it was renamed to “By Distance” and moved to the Vertex – Merge Vertices menu.

In Blender 2.83 this menu was moved to the context menu, activated by the right mouse click. And quick call by the “m” hot-key.

How to get global vertex coordinates

To get the vertex coordinates in the scene global coordinate system when the object’s scale was not applied, we need to multiply the local vertex coordinates by the object world transformation matrix:

How to return the familiar selection mode from Blender 2.7 in Blender 2.8

In Blender 2.8 the selection mode has been changed. The “select all” command is still mapped to pressing the “a” key, but the “deselect all” command in Blender 2.8 is now mapped to a double-click of the “a” key or to the “alt + a” key combination. However, it is easy to return the familiar selection mode from Blender 2.7 – selecting and deselecting all by pressing one “a” key.

To do this, in the “Preferences” window in the “Keymap” section type “object.select” in the search field. In the search results in the “Object mode” section in the line with “a” key snapping set the “Toggle” value to the “Action” parameter.

This will return the familiar selection in object mode.

How to resize panels in Blender UI

In order to resize the T- or N-panel of the Blender UI, you just need to hold the edge of the panel with the mouse and drag it left or right. However, in this case, you can only change the size of the panel itself, but not the interface elements on it.

To change elements size and the font size of the panel, you need:

  • hover cursor on the panel
  • hold together the “ctrl” keyboard button and the middle mouse button (scroll wheel)
  • move the mouse up or down

This works not only for the side panels but also for all the “Properties” window.

Fast moving modifiers in the stack

The “shift+r” key combination, which repeats a perfect action, works not only with editing a mesh but also with the Blender interface. For example, with this key shot, we can simply move the modifier in the modifier stack up and down, without hunting the runaway arrows.

Simple rotation around edge

It is difficult to rotate mesh polygons around an edge if this edge is not parallel to the global X, Y, or Z axis — we need to switch to the edge local coordinate system, fix axes, and then rotate polygons about these axes. However, this can be done easier and faster – position the viewport parallel to one of the edges local axis and perform a rotation by simply pressing the “r” key.

To quickly rotate polygons around the edge:

  • switch to the “by Active Element” mode,
  • select geometry to rotate
  • next select the edge, around which you want to rotate the geometry. Selected last it becomes an active element,
  • press shift + Num1 (Num3 or Num7) to set the viewport parallel to one of the edge axes,
  • rotate geometry by pressing the “r” button.
