MDD Deformer

Updated: 3 Feb 2025

Deform a mesh based on an MDD file

Method #

This node deforms a mesh based on an MDD file. MDD files are linked to the mesh they are exported with, and not all tools can export them.

Parameters

Transform

These properties control the 3D transforms of the node. Transforms will generally be inherited by child nodes, although they can be ignored through the Inherit Transform Channels attributes.

Parameter	Details
Position X	The objects position along the local x-axis.
Position Y	The objects position along the local y-axis.
Position Z	The objects position along the local z-axis.
Rotation Heading	The objects rotation around the local y-axis.
Rotation Pitch	The objects rotation around the local x-axis.
Rotation Bank	The objects rotation around the local z-axis.
Scale X	The objects scale along the local x-axis.
Scale Y	The objects scale along the local y-axis.
Scale Z	The objects scale along the local z-axis.

Parent Transform

Control the inheritance of the transforms from the parent.

Parameter	Details
Position	Toggle inheritance of the Position from the parent.
Rotation	Toggle inheritance of the Rotation from the parent.
Scale	Toggle inheritance of the Scale from the parent.
World Position Only	Inherit the world position from the parent only, rotation and scale will be ignored. Overrides above properties.
Inherit Time	Toggle inheritance of time from the parent.

Attributes

These properties control the core behaviours of the node.

Parameter	Details
MDD File	Source file for the MDD Deformation.
Playback Time	Absolute time the animation is played at.
Loop Start	If the MDD Deformer loops, choose where it loops back to.
Playback Offset	Offset the time the MDD deformer starts at.
Playback Speed	The speed at which the MDD deformer animates.
Loop Mode	Control how the animation is after finishing Play Once : The animation plays once and no longer effects the mesh. Looping : The animation loops infinitely.
Blend Mode	Choose how the falloff blends with the model. None : No falloff is applied. Blend : Finds a middle value between its deformation and the model’s current positions. Additive : Always adds the new deformation on top of the model’s current positions.
Falloff	Controls the falloff of the MDD deformation.

Inputs

Name	Description	Typical Input
Falloff Node	Use an input node to control the transformation values of the falloff.	Null
Transform Modifiers	Apply the transforms of another node to this node.	Null
Target Node	Modifiy the rotations of the node to always direct the z axis towards the input.	Null
Local Transform Override	Apply the transforms of another node to this node, relative to its parent.	Null
