What are some of the most useful and versatile nodes for 3D modeling and why?

1 Geometry Nodes

Geometry nodes are nodes that create, modify, or combine 3D shapes. They can be used to generate procedural geometry, such as trees, rocks, or buildings, based on parameters and inputs. They can also be used to deform, transform, or subdivide existing geometry, adding detail, variation, or animation. Some examples of geometry nodes are Point Distribute, Mesh to Volume, Boolean, and Subdivision Surface.

2 Shader Nodes

Shader nodes are nodes that control the appearance of the 3D models, such as their color, texture, reflectivity, or transparency. They can be used to create realistic or stylized materials, such as metal, wood, glass, or skin, using different types of shaders, such as Principled BSDF, Emission, or Mix Shader. They can also be used to apply image textures, procedural textures, or masks, using nodes such as Image Texture, Noise Texture, or Color Ramp.

3 Math Nodes

Math nodes are nodes that perform mathematical operations on values, such as adding, subtracting, multiplying, or dividing. They can be used to create complex or dynamic effects, such as gradients, patterns, distortions, or animations, using nodes such as Math, Vector Math, or Map Range. They can also be used to control the inputs or outputs of other nodes, such as the strength, scale, or rotation of a shader, geometry, or modifier node.

4 Group Nodes

Group nodes are nodes that allow you to group multiple nodes into a single node, with custom inputs and outputs. They can be used to simplify, organize, or reuse your node networks, making them more manageable and modular. They can also be used to create custom functions or operations that are not available as individual nodes, such as a cloud generator, a water shader, or a cloth simulator.

5 Switch Nodes

Switch nodes are nodes that allow you to switch between different inputs or outputs based on a condition, such as a value, a boolean, or a trigger. They can be used to create variations, alternatives, or options for your 3D models, such as different colors, textures, or shapes, using nodes such as Switch, Mix RGB, or Mix Shader. They can also be used to create conditional logic or events for your 3D models, such as changing their appearance or behavior based on time, location, or interaction.

6 Input Nodes

Input nodes are nodes that provide data or information to your node networks, such as values, vectors, colors, images, or geometry. They can be used to define the parameters or inputs for your 3D models, such as their size, position, rotation, or material, using nodes such as Value, Vector, Color, or Texture Coordinate. They can also be used to import external data or information from other sources, such as files, cameras, lights, or objects, using nodes such as Image Texture, Camera Data, Light Path, or Object Info.
