AABB Max

Returns the maximum value in each dimension of the axis-aligned bounding box containing the mesh.

AABB Min

Returns the minimum value in each dimension of the axis-aligned bounding box containing the mesh.

Bone Indices

Returns bone indices for skinned meshes. One index is contained in each xyzw component.

Bone Weights

Returns bone weights for skinned meshes. The 'x' component is a max-weighted component clamped to 0.99.

Camera Aspect

Aspect ratio (width / height) of the camera.

Camera FOV

Field of view of the camera in degrees.

Camera Far

Far plane distance of the camera.

Camera Forward

Direction vector that the camera is facing.

Camera Near

Near plane distance of the camera.

Camera Position

World position of the camera.

Camera Right

Camera's right facing direction vector.

Camera Up

Camera's up facing direction vector.

Delta Time

Time elapsed since last frame.

Depth

Returns the camera depth of the surface

Elapsed Time

Total time elapsed.

GSplat Data

Exposes the raw attributes of the splat, which are the parameters to the vertex shader used to position the splat ellipsoid in 3D space.

Hair Debug Color

Visualizes hair strands as different colors depending on their type: green for base strands, blue for strands generated by single strand interpolation, red for strands generated by multi strand interpolation.

The "Debug mode" checkbox must be enabled on the Hair Visual Component for this node to work.

Hair Strand ID

The hair strand ID as a float value, but divided by 65535.

Is Fallback Mode

Provides a way to bypass advanced shader features and effects which can improve stability and performance on a wide variety of devices.

Matrix

Outputs a transformation matrix from the engine, based on the selected Type.

Skin Matrix

Get the skin matrix at a given bone index. Note the skin matrix is not available in the fragment shader.

Stereo View Index

Index of the current stereo view. For stereo cameras, returns 0 for the left eye view and 1 for the right eye view. Returns 0 for mono cameras.

Text Data

Per-pass text data (Pass ID, colors, coverage mask, SDF distance, and UV) for building custom Text materials.
