Questions tagged [shader-nodes]

Questions specific to shader nodes, the nodes available for creating materials in the shader editor.

Shader Nodes are the nodes used in the Shader Editor to create Materials that generate the colors and possibly displacement of objects.

This tag should be used on questions about the specific inputs, outputs, or settings of shader nodes as well as questions about how to connect shader nodes to create node trees that compose materials.

Can I measure a light's distance with nodes?

I know I can separate RGB into 3 branches and assign different functions to each one. This selecting method doesn't work if there are white lights in the scene so I need to add an additional criteria to make this system work. Can I add a criteria…

Checker Shader Node - strange distortion Blender 2.92.0

I've been working on a long-term project and am in the process of unwrapping the objects. One of the materials I'm using is created from Checker Shader Node. I tend to use this during unwrapping to help me determine if any major distortion is…

How can I create a 3D radial "beams" with shader nodes?

I would like to create a proceedural texture in which "beams" eminate from the center of an object - think of light beams coming out of a point light source. The following node set-up does this perfectly in 2D: However if applied to a sphere you…

How does blender converts a color into a factor

Say I have a constant RGB color value and plug it into the input factor of the color ramp. Does anyone know how does blender casts a RGB color to a one dimensional value? Does it first compute the amplitude of the color vector and then passes that…

Color burn function in mix RGB node

Hey guys I have a doubt about the color burn function in the mix RGB node in the blender. The formula for the color burn is 1-(1-a)/b, but when I change the first input to 0.8 and the second input to 0 then the color burn function outputs like the…

How can I make Fresnel edges softer?

Below is a poorly drawn representation of what Fresnel does to my model: it covers part of it with a hard edge. And this is what I want to be able to do; this illustration shows the Fresnel with a softer edge: Is there any way to do this?

What's the difference between the Wave Texture Nodes outputs?

Here's the Wave Texture Node: It's got two outputs: "Color" and "Fac" The documentation defines them as "Texture color output," and Factor is defined as "Texture intensity output." Experimentally, these always seem to be produce the same thing, as…

It it possible to rotate the material to match the normal of the face it's on?

I've been starting to look into parallax mapping, mostly to recreate some video game materials for a potential animation. I've managed to get it to work when the mesh is in its default orientation, but the effect completely breaks when I rotate the…

Node group that doesn't touch a certain attribute

I'm trying to figure out how to create a material node group that only affects certain Principled BSDF values. As a simple example I have a cube in which each of the 6 planes have a different Base Color. Let's say I want to create a group and leave…
