Houdini 20.5 Nodes

VEX networks

Containers for VOP networks.

These nodes are containers for VOP networks.

Nodes

Channel nodes

Channel nodes create, filter, and manipulate channel data.
Compositing nodes

Composite nodes create, filter, and manipulate image data.
Copernicus nodes

COP nodes provide real-time image manipulation within a 3D space.
Dynamics nodes

Dynamics nodes set up the conditions and rules for dynamics simulations.
LOP nodes

LOP nodes generate USD describing characters, props, lighting, and rendering.
Object nodes

Object nodes represent objects in the scene, such as character parts, geometry objects, lights, cameras, and so on.
Render nodes

Render nodes either render the scene or set up render dependency networks.
Geometry nodes

Geometry nodes live inside Geo objects and generate geometry.
VEX networks

Containers for VOP networks.
VOP nodes

VOP nodes let you define a program (such as a shader) by connecting nodes together. Houdini then compiles the node network into executable VEX code.
TOP nodes

TOP nodes define a workflow where data is fed into the network, turned into work items and manipulated by different nodes. Many nodes represent external processes that can be run on the local machine or a server farm.
APEX nodes

APEX nodes provide operations for building up the functionality of APEX graphs, which are used in KineFX to create character rigs and perform other geometry manipulation.
