[Solved] Ubuntu using blender script error: Numpy cannot be found

When rendering with blender script on Ubuntu 16, use the command blender — background — Python * Py, an error is reported and numpy cannot be found. But I installed numpy in CONDA environment, so I was puzzled.

Later, I learned that blender has its own Python interpreter. When running my py script, the built-in Python interpreter does not install the numpy extension library, so an error is reported.

Solution:

Find the Python interpreter directory for blender in your environment.
Open blender, shift+F4 and go to blender's Python interpreter
You can see the version of Python that comes with it, then use whereis python for that version and find the interpreter's directory
Use sudo apt-get install python version-numpy to install the third-party library for blender's own Python interpreter

Insert keyframe giving keying set failed to insert any key frames (solved)

Blender 2.81 beta

problem description

After entering the posture mode , adjust the posture, and then press the I key to try to insert the key frame, but the error message is very difficult to understand

Frame position to insert key

So switch to the English version

“Insert keyframe giving keying set failed to insert any key frames”

On the Internet, it is said that the channels to be inserted are locked, but I did not lock them. At present, there is no good solution. You have to right-click to add frames in the N panel’s transform menu. I don’t know if this is a bug or not

solutions

In the scene attributes tab, check the insert frame set list. If the data named keying set or keying set.001 is in the list, just delete them

Delete completed

Then press the I key to insert the keyframe normally

Note: in fact, the so-called keying set is a very convenient mechanism. You need to select all the channels you need in advance and put them into a set. Then, when you press I key, blender will automatically insert frames for the channels in the set.

Blender graphic tutorial: loop cut for polygon modeling commands

The polygon modeling command is only available under edit mode

this command is called Loop Cut and Slide short for Loop Cut shortcut key (Ctrl + R)


Blender loop cut operation design is very smooth. The basic steps are as follows:

    first press the shortcut key on the object to be looped Ctrl + R. At this time, different previews will be generated with different mouse positions. When previewing, scroll mouse wheel up and down to increase or decrease the number of ring cut edges, and the preview effect will also change accordingly (this step is optional). If you are satisfied with the preview, click the left mouse button. Slide the mouse to move the cut edge of the ring (optional). If you are satisfied with the preview, click the left mouse button again.

The whole process requires two left mouse clicks
