Syntax
UCLASS (Abstract)
class UMovieGraphCoreTimeStep : public UMovieGraphTimeStepBase
Remarks
Provides common logic for typical time-step functionality.
The number of temporal sub-samples is read from the graph for each output frame, and we then take the time the shutter is open and break it into that many sub-samples. Subclasses must implement GetNextTemporalRangeIndex() to indicate the index of the next temporal sub-sample.
Variables
| Type | Name | Description | |
|---|---|---|---|
 |
FCurrentFrameData | CurrentFrameData | Frame Metrics are constant data updated once per output frame, while CurrentFrameData is keeping track across engine ticks to work towards producing a single frame. |
 |
FOutputFrameMetrics | CurrentFrameMetrics | A set of cached values that are true for the current output frame. |
   |
FMovieGraphTimeStepData | CurrentTimeStepData | This is the output data needed by the rest of MRQ to produce a frame. |

Overridden from UMovieGraphTimeStepBase
| Type | Name | Description | |
|---|---|---|---|
   |
FMovieGraphTimeStepData | TickProducingFrames will be called for a frame (before the frame starts) and then this will be called at the end of the frame when we kick off the renders for the frame. | |
   |
bool | IsExpansionForTSRequired
(
const TObjectPtr< UMovieGraphEvaluatedConfig >& InConfig |
When expanding shots, do we need to expand the first frame by one extra to account for how temporal sub-sampling can sample outside the first frame (due to centered frame evals). |
  |
void | Called each frame while the Movie Graph Pipeline is in a producing frames state. |
