Texture pixelization

The simplest way to pixelate texture, procedural or not – get the color from the single pixel and fill the region with required width and height (resolution) with this color.

Here is the gradient texture with red – green – blue colors:

To pixelate it with the first step of resolution we can make some vectors manipulations.

Quick Instance Add-on: grouping-like workflow

This add-on for Blender 2.8 creates a grouping workflow using Blender 2.7 group style. Add-on doesn’t “brokes” the scene, so you can properly work with groups made with this add-on having no add-on installation.

By Michael Soluyanov.

  • ctrl+g – group selected objects
  • f9 – manage the group name and origin
  • tab – enter/exit group edit mode in separate space

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.

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.

Changing objects visibility in the viewport and while rendering

The easiest way to hide and show rendering objects is to assign animation keys to them. To do this, move the cursor over the eye icon (visibility in the viewport) or camera (visibility when rendering) in the Outliner window, press the “i” key and then manage the created condition in the Graph Editor like the ordinary animation keys.

But this method is not always available. For example, we cannot assign visibility animation keys for collections, Blender will generate errors like:

“hide_viewport” property cannot be animated

or

“hide_render” property can not be animated

However, using the Blender Python API, we can control the visibility of such objects.
