Now, use the command click dropdown menu again to create your first Math Node. A Numeric ("Val") preview is grayscale, the others may or may not be in color. By clicking on an output connector (the dot graphic) you’ll toggle a representation of the how the input values are interpreted on a 3D sphere. On each Node, the values listed on the left side are input values, the ones on the right are output values. These will be used to create Red, Blue and Green values you can edit manually, as well as an Alpha value, to handle transparency, something even the dedicated Color Node doesn’t do. Under the Add Node item, go to the Constants submenu and create a Number Node. Then, command click in the screen to display the Node Editor’s dropdown menu. Just command click on the Node editor screen and select the PBR Shader from the dropdown’s Shaders submenu group.) With a very few exceptions, it seems to give me greater control of the final texture. (Whenever I do this, nowadays, I almost always replace the default Materials Shader with the newer PBR Shader. There are several easier ways to build a color, but this will get you into the habit of thinking of colors as a set of numbers instead of as a single value.įirst, create a Default Material, select it, and switch to the Nodes Editor by clicking the Nodes Tab located towards in the upper left of the main screen. I’ll talk about them in the first example. To convert between these formats, there are a pair of Math Nodes, Vec2Float and Float2Vec. The Y and Z fields may not affect the output if the process expects a Number instead of a Vector input. The interfaces may not change, but usually, a single value is stored in the X component’s field. Most nodes will generate output as vectors ( X, Y, and Z values, referred to as “Vec” or “Color” ) and/or as Numeric, floating point values ( referred to as "Val".

In this thread, intend to talk more about understanding the numbers than digging into any particular Node. Lots of good info and brief definitions of Cheetah3D’s Nodes. I STRONGLY recommend reading the thread “ Quick And Dirty Introductions to Node-based Shaders” by PodPerson. This is almost all based upon observation, not formal education. Once I get technical, I may very well be wrong. I’ll start with the basics and work my way up, so please forgive me when I run out fo fuel somewhere in the middle, because I certainly don’t know it all. To do that (and keep it comprehensible), I’ve got to explain a few things about what I know, what I don’t know, and many things I’ve guessed.

I’ve been asked to add some comments to the forum about how I approach designing Node-based textures.
