In Blender 2.8 node connectors in the “Shader Editor” window are straight by default, unlike earlier versions, where they bent curving. To return the usual connections bend, change the following settings:
Open the “Preferences” window
Switch to “Themes”
Expand the “Node Editor” tree branch
In the “Node Curving” field, set the value greater than 0. 0 means straight lines, the larger – the greater bend. A value of 4 corresponds to the bend that was in Blender 2.7x versions.
Interface elements in custom user panels often do not correspond to each other in size. As a result – the overall panel layout does not look beautiful. As an example, let’s create a custom panel and place an operator button and an input text field on it.
To change the camera height in the “walk/fly” mode in the 3D Viewport window (enables with shift + ` keycode), you need to on the “Gravity” checkbox in the “Preferences” window – “Navigation” and tune the height with the “View Height” parameter.
When you make a button in a custom UI to call the operator with passing the necessary parameters to it, pay attention that only the parameters specified explicitly will be sent to the operator. Other operator parameters will remain with default values.
For example, we need to execute the “transform_apply” operator – applying object transformations with applying just the scale.
In Blender 2.79, mesh vertices were highlighted in the “tweak” selection mode by holding down the “shift” key and a slight cursor movement with the right mouse button pressed. This allows quickly add vertexes to the selection without aiming each vertex with sniper accuracy.
In Blender 2.8x, this method has become unavailable due to the left click selection change. For those users who remained on “the right click select”, nothing has changed, everything works as before. The “tweak” selection was broken only for those who switched to the left click selection.
To use the “tweak” selection with the left click select, you need to make the following changes into the keyboard shortcut settings:
