MDD surface node

Animates points using an MDD file.

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.

Warning

Point numbers in the input geometry must match point numbers in the MDD file.

Parameters

MDD File	The name of the file to be read.
Frame	The frame to read from the MDD file. This defaults to `$FF`. Tip To offset the animation to start at a different frame, use the expression `$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.
Reload MDD	Force a reloading of the file.
Interpolation	Type of interpolation to be used for inter-frame evaluation of the MDD file.
Coordinate System	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.
