Movie Graph Warm Up Setting Node

C++ Source:

• Plugin: MovieRenderPipeline

• Module: MovieRenderPipelineCore

• File: MovieGraphWarmUpSettingNode.h

Editor Properties: (see get_editor_property/set_editor_property)

• dynamic_properties (InstancedPropertyBag): [Read-Write] Properties which can be dynamically declared on the node (vs. native properties which are always present).

• emulate_motion_blur (bool): [Read-Write] If true, we will evaluate frame 0, and then wait NumWarmUpFrames frames, rendering each one as we go. Then we will evaluate frame 1, and then frame 0 again. This emulates motion blur on the first frame (which normally needs data before frame 0). If false, we will “walk” towards the first frame of the shot, starting NumWarmUpFrames before the shot normally starts.

• layer_warm_up_frames (int32): [Read-Write] The number of warm-up frames to run before each render layer’s final render, with that layer’s modifiers active. Layer warm-up frames let Lumen’s lighting converge to the layer’s contents before rendering the frame that’s actually written to disk. Contrast with NumWarmUpFrames, which runs at the start of the shot rather than per-layer.

  Layer warm-ups are helpful when layer contents change substantially in ways that affect lighting.

• num_warm_up_frames (int32): [Read-Write] At the start of each shot, how many frames should we run the engine (without writing renders to disk) to warm up various systems.

• override_b_emulate_motion_blur (bool): [Read-Write]

• override_layer_warm_up_frames (bool): [Read-Write]

• override_num_warm_up_frames (bool): [Read-Write]

• script_tags (Array[str]): [Read-Write] Tags that can be used to identify this node within a pre/post render script. Tags can be unique in order to identify this specific node, or the same tag can be applied to multiple nodes in order to identify a grouping of nodes.
