How to make node connections in Blender 2.8 not straight, but curving as before
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.
How to randomly shift texture on objects
To shift the texture randomly on different objects, the easiest way is to change its location along any of the axes by a random value.
Random Per Island
In Blender 2.82 we can get a random index of UV islands in the Shader Editor through the “Geometry” node
Works only for the “Cycles’ render engine.
Base PBR-materials scheme
The basic scheme for making a PBR (physically based) node shader in Blender looks like as follows:
Note that all the “ImageTexture” nodes, except for the “Base Color” node, use the “NonColor” colorspace.
Node Font – font shader by nodes
Procedural shader with Latin font made with Blender nodes.
By Sam (Worldsday) Brubaker
Available in the BIS library.
Simple way to manage the SSS radius
In Blender 2.81 with the “Vector Math” node we can simple regulate the subsurface radius:
Creating a circuit board with shader nodes
Simon Thommes published his stream about making a circuit board with shader nodes in the nodevember challenge.
Making a procedural zipper shader
Hans Chiu shared a stream about making a procedural animated zipper material.
Nodevember
Nodevember is a monthly challenge you invited to make procedural objects for Blender every day. It can be a material, a shader, an object, anything, if only it would be procedural. “If you can call it nodes, you can call it Nodevember!”
