This output operator is used to write an MDD animation file based on point locations in a particular geometry. The number of points in the geometry must not change, and the frame range must monotonically increase.
Begins the render with the last render control settings.
Opens the render control dialog to allow adjustments of the render parameters before rendering.
Render with Take
Uses the settings in a particular take while rendering. Choose Current to use the current take when rendering.
Valid frame range
Limits the rendering of frames, when set to Render frame range or Render frame range only.
Render any frame
Allow the renderer to render any and all frames.
Render frame range
Only render the frames in the range set below, but allow the renderer to render other frames if they are referenced by in-range frames.
Render frame range only (strict)
Only render the frames in the range set below, and don’t allow the renderer to render other frames, even if they are referenced by in-range frames.
The SOP node which contains the points used to write the file.
Name of the MDD file to write.
Specifies the frame at which to cook the rest geometry.
Specifies whether the geometry should be transformed into world space before written out.
Specifies a scale on the geometry before written out.
The coordinate system used in the MDD file. If this is set to Right-Handed, z coordinates will be negated upon writing from Houdini’s native left-handed coordinate system.
Relative Time Values
If set, time values will be written out relative to the starting frame.
To import an MDD file that was saved with this option enabled, the
Frame parameter of the MDD surface node should use the
$FF+1-start frame instead of
$FF. For sequences
starting at frame 1 though, this is not necessary.
Initialize Simulation OPs
Force all simulation OPs to be reset. This includes DOP Networks, POP SOPs, and other OPs that cache their results.
This is the safest way to render out a simulation, because it starts the simulation from scratch and discards any partial simulations you might have done with different parameters.
The current frame of the range specified. This always starts at 1.
Total number of frames being rendered.
