Editing Physics Asset Physics Bodies

Below are a number of common procedures, and steps, associated with editing Physics Bodies in the Physics Asset Tool.

Editing a Physics Body

  1. Enable Body Editing Mode icon_PHatMode_Body_40x.png.

  2. Select a Physics Body in the Viewport or in the Hierarchy Pane.

    • If it is difficult to see the Physics Body you desire, use the Viewport -> Modes -> MeshRender Mode -> Wireframe/None to adjust the visibility of the Skeletal Mesh.

  3. Move, rotate, and scale the Physics Body using the Translation, Rotation, and Scale tools so it fits the Skeletal Mesh and Skeletal Joint.

  4. Edit the Physics Body's properties in the Details Pane.

  5. Enable or Disable Collision between the current Physics Bodies and other in the Physics Asset using the Collision On and Collision Off tools. Any Physics Body that can collide with the currently selected Physics Body will be blue, if they cannot collide, they will be gray.

  6. If a series of bodies should act as one, such as with the twist joints that form a wrist, use the Weld tool to prevent undesired physics simulation behavior. Welded Physics Bodies will be yellow in color.

  7. Save icon_SaveAsset_40x.png often.

See the Physics Asset Tool Reference for more information on the properties in the Physics Asset Tool.

Copying Physics Bodies

While in either mode, properties from one Physics Body can be copied to other Physics Bodies:

  1. Select the Physics Body you wish to copy data from.

  2. Press Ctrl + C.

  3. Select the Physics Bodies you wish to apply data to.

  4. Press Ctrl + V.

This will not overwrite the shape of a Physics Body.

Deleting Physics Bodies

  1. Enable Body Editing Mode icon_PHatMode_Body_40x.png.

  2. Select a Physics Body you wish to delete.

    • If it is difficult to see the Physics Body you desire, use the Viewport -> Modes -> MeshRender Mode -> Wireframe/None to adjust the visibility of the Skeletal Mesh.

  3. Press the Delete key.

Physical Materials

Each Physics Body in a Physics Asset can have a Physical Material assigned to it. To apply a Physics Material to a single Physics Body:

  1. Enable Body Editing Mode icon_PHatMode_Body_40x.png.

  2. Select a Physics Body in the Viewport or in the Hierarchy Pane.

    • If it is difficult to see the Physics Body you desire, use the Viewport -> Modes -> MeshRender Mode -> Wireframe/None to adjust the visibility of the Skeletal Mesh.

  3. In the Details pane, locate the Simple Collision Physical Material property and assign a Physics Material.
