This operator allows you to read in an MDD file previously created using the MDD Point Cache ROP, or another package, and animate the input geometry based on the point locations specified in the MDD file.
If there is no input geometry, then points with no connectivity will be created to represent the MDD file.
Point numbers in the input geometry must match point numbers in the MDD file.
The name of the file to be read.
The frame to read from the MDD file. This defaults to
To offset the animation to start at a different frame, use the
$FF+1-start frame instead. Note that when exporting
such an imported sequence, you should set the starting frame value
to be start frame as well in the MDD Point Cache render node.
Force a reloading of the file.
Type of interpolation to be used for inter-frame evaluation of the MDD file.
The coordinate system used in the MDD file. If this is set to Right-Handed, z coordinates will be negated upon loading to match Houdini’s native left-handed coordinate system.
Shift to Frame 1
The frame read from the MDD file will be offset such that it will begin at frame 1.
MDD_FSTART, MDD_FEND, MDD_NFRAMES
The frame range of the loaded MDD file.
MDD_TSTART, MDD_TEND, MDD_TFRAMES
The frame range of the loaded MDD file expressed as times using the scene’s current $FPS.
