An optional camera input. The scene is rendered from the perspective of this camera. If the camera input is not connected, SplatRender uses a default camera positioned at the origin and facing in the negative Z direction.

Connect to the scene you want to render.

Specifies the mask pattern to target the splats you want to include in the render. This defaults to Custom: {isa:ParticleField_3DGaussianSplat} which targets any splats in the scene.

You can also use standard glob-style variables, such as /*, to create masks.

Default - Injected/All Roots - selects the default prim(s) for the node. The default will be the injected mask prim paths if there is an upstream node with this. Otherwise the default mask for this node type is evaluated.

All roots - selects the top level Xform(s) in your scene.

Last modified - selects whatever the last node modified was.

All Cameras - selects all Cameras in your scene graph.

All Lights - select all lights in your scene graph.

All Meshes - selects all meshes in your scene graph.

Custom - sets a custom selection of prims that exist in your scene graph.

on: Output classic-style Nuke Z which is l/Z-distance. ‘No Object’ is black 0.0 and the Z value *decreases* the further from camera. This is convenient to use in a compositor because it looks and acts much like a color channel and can be directly viewed. It will also pass through a filter without creating illegal ‘nan’ floating-point values.

Note that 1/Z is -NOT- normalized Z. 1/Z is easily converted back to absoluteZ-distance by using another 1/Z. Normalizing involves scaling the Z by some near/far range and thus destroys the scene- space scale of the distance value.

off: Output absolute Z-distance where ‘No Object’ = inf and the Z value increases the further from the camera. This is the world-space distance from the camera to the object.

The number of ‘time segments’ used to interpolate motion blur. A segment count of 0 effectively disables motion blur, while a segment count of 1 creates a straight line blur. Increasing the number of segments beyond 1 subdives the straight line into more time segments, which is normally only necessary for heavy rotational blur. The greater the number of segments the greater the quality of rotational motion blur.

Note - if the camera or object motion is mostly linear increasing shutter segments should not produce any significant change in the motion blur’s appearance.

Select when the shutter opens and closes in relation to the current frame value when motion blurring:

• centered - to center the shutter around the current frame. For example, if you set the shutter value to 1 and your current frame is 30, the shutter stays open from frame 29.5 to 30.5.

• start - to open the shutter at the current frame. For example, if you set the shutter value to 1 and your current frame is 30, the shutter stays open from frame 30 to 31.

• end - to close the shutter at the current frame. For example, if you set the shutter value to 1 and your current frame is 30, the shutter stays open from frame 29 to 30.

• custom - to open the shutter at the time you specify. In the field next to the dropdown menu, enter a value (in frames) you want to add to the current frame. To open the shutter before the current frame, enter a negative value. For example, a value of -0.5 would open the shutter half a frame before the current frame.

Nuke has always defaulted to start and going forward in time, so at a given frame the shutter is open. However often it can be useful to change this to end when you want a motion blur trail to an impact point on a specific frame.

Shifts the time frame of input geometry, lights and cameras while keeping the renderer at the same output frame.

This means you can slip your render in time (with subframe accuracy) without affecting the camera or the objects in the stage, which can be really helpful when you are trying to slip the camera to get vector motion blur aligned properly.
