PREVIEW VIDEO

100% Blueprint with no C++, no additional plugin.

Now it supports animated hands and feet by default, but the former blueprint is still included independently.

There is an improved version for the better optimized experience especially in VR.


IMPORTANT : Cut here until your work is finished!

In UE4, pawns always run its construction script when you do something on them in editor.

So if you cut the construction script while working, there will be no slow down :)


If your humanoid character is rigged to Epic Skeleton,

  1. Remove all body parts except for pelvis (Don't modify skeleton tree) and then import it
  2. When importing, replace its skeleton to "SK_Sliceable_Mannequin_Skeleton"
  3. When importing, replace its physics asset to "SK_Sliceable_Mannequin_PhysicsAsset"
  4. Set it as a mesh of "BP_Sliceable" and replace other static mesh components to proper mesh

Then it will just work!

Else, please send me a mail to request for documentation about how to adopt it to the non-Epic Skeleton from the bottom up.


Technical Details

Features:

  • Slice skeletal mesh while animated or ragdoll
  • Slice every single part of body (except for pelvis)
  • No precut nor designated. Cutting planes are generated instantly as you intended
  • One slicing for each bone is guaranteed
  • Option for multiple slicing for each bone (Physics simulation is partially supported in this case)
  • Option to stop animation or keep playing after sliced
  • Easy to adapt to humanoid characters especially rigged to Epic Skeleton

Notices:

  • Best for robots, mannequins, arthropods and armored men like Stormtroopers or the Black Knight
  • May not proper to organic, elastic, set of meat chunk (because this trick is based on static meshes)
  • Need to import each body part of characters you want to use
  • If you want to use a custom skeleton tree which is different from Epic Skeleton, you have to add some sockets and constraints to your skeleton and physics asset as I did
  • Hands and feet can be animated by renouncing sliceability. You have an option for them
  • It doesn't provide some magical tools, but it shows how to build up your sliceable skeletal mesh based on the procedural mesh
