• copy the path, and go commandline (type D: enter if your blender in D drive, C drive no need):
  • for Mac and Linux, same, just cd to that directory, and do above. the drive letter thing is just for windows, if you prefer to put app in other drive
  • run command code

    cd D:\YourPathToThat\blender-2.83.0-windows64\2.83\python\bin
    D:
    .\python.exe -m pip install PySide2

Blender Special shortcut

modelling shortcut in blender

Blender is 2nd 3D application I picked up when I was starting the 3D learning. (Cinema 4D is my first 3D app, Maya is my 3rd, 3DS Max is my 4th).

Before 2.6, the Blender interface is the most struggling thing to cope with,

• short named buttons
• unconventional shortcut oriented operation, wield layout

But now, as 2.6 comes with a new interface, it pops up and let you use optional Maya user interaction;

Now I started to pick it up again.

• number pad
• focus on selected: Num (.)

Seperate object

• Tab to EDIT mode, SPACE-EDIT-VERTICES-SEPARATE .. “p”

Select edge loop

• alt + RMB click

Steps:

1. Many surfaces need to be “cut” to make it possible to unwrap them.
2. The edges that will be cut “Seams”. In Edit Mode, selected edges can be marked or cleared as seams, using Mesh → Edges → Mark Seam (Ctrl E)
3. UVs → LSCM Unwrap (E Key) in the UV editor will launch LSCM unwrapping
