Parameters
These properties control the core behaviours of the node.
Parameter Details Preview In Viewport
Preview the generated image as an overlay in the viewport.
- Off : No preview is generated.
- RGBA : Preview the image blended with alpha in the viewport.
- RGB : Preview the colour channels in the viewport.
- Alpha : Preview the alpha channel in the viewport.
- PIP : Preview the image blended with alpha in the viewport, in a smaller picture in picture display, on top of the existing content.
Apply PostFX Before Alpha Image Input (Legacy)
When enabled, the alpha input image is applied after the postfx pass, overwriting any effects the postfx would have applied to the alpha channel.
Depth Scale
Control the scale of the depth in the normal map.
Invert Normal X
Invert the direction for the normals generated along the X axis. This will affect the direction lighting appears to come from on the surface.
Invert Normal Y
Invert the direction for the normals generated along the Y axis. This will affect the direction lighting appears to come from on the surface.
Invert Normal Z
Invert the direction for the normals generated along the Z axis. This will affect the direction lighting appears to come from on the surface.
The properties control the time at which the node is active. See Timeline for editing time segments.
Parameter Details Duration
Control the duration of the node’s time segment.
- Composition Duration : Use the length of the composition for the node’s time segment duration.
- Custom : Set a custom duration for the node’s time segment.
Node Time
The custom start and end time for the node.
Duration (Timecode)
The length of the node’s time segment (in time).
Duration (Frames)
The length of the node’s time segment (in frames).
Time Segment Enabled
Set whether the node’s time segment is enabled or not in the Timeline.
