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

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.

ParameterDetails
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.

Control the inheritance of the transforms from the parent.

ParameterDetails
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.

These properties control the core behaviours of the node.

ParameterDetails
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.
