Removing custom normals from all selected objects in Blender

Most often, we need to clear custom normals when importing objects from external scenes. We can remove custom normals manually by selecting meshes in the scene and pressing the Clear Custom Split Normals Data button in the Properties panel on the Data tab of the object. However, if there are many such objects, we can write a simple script using Blender Python API that will quickly clear the normals on all selected objects.

Solving the problem of the discrepancy between the size of the track section and the profile applied to it

By Andrew M.

“Many letters about the simple”

I need a frame. No, two frames: one larger, the other smaller, but made from one profile. I drew a rectangle, set the desired dimensions, duplicated, set other sizes. I drew a separate profile. For a section to both rectangles I applied this profile. … why did I get different frames? And none matches the size of the profile? Ah, I forgot to apply the scale. Applied. The dimensions of the cross-section changed, became different, but again not equal to the profile. How to make them equal – read below!

Solving the problem of the discrepancy between the size of the track section and the profile applied to it

This problem occurs when the path for profiling is constructed in any way but then scaled to the desired size. In this case, it does not matter if its scale is 1 or not. If we apply the profile we need to it, then it will be different in size from the set … Why? We will see now.

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

Fake-bpy-module

Code autocomplete greatly simplifies writing scripts or developing add-ons for Blender. One of the best autocomplete modules for today is developed by Nutti. Last updated 20190718.

The project is hosted on the author’s GitHub: https://github.com/nutti/fake-bpy-module

The modules are distributed via pip or as a pre-generated-modules. Author also provides a module generator with which you can assemble autocomplete modules yourself.

How to protect your add-on from downloading through aggregators

With the Blender popularity growing, the number of add-ons created for it by third-party developers is growing too. A lot of high-quality professional add-ons are written for Blender now. Over time, the number of add-ons is becoming more and more. And on this wave aggregators appeared – programs and services independently searching for add-ons and allowing Blender users to install add-ons quickly, many at once, and bypassing add-on distribution channels selected by their authors. What caused a negative reaction of add-on developers.
