In this How-To, we will cover the basics of creating a Constraint Profile and adding Physics Constraints to it.
Steps
-
Find or Create a Physics Asset for your Skeletal Mesh using the Content Browser.
If opting to create a new Physics Asset, you will need to set it up before continuing.
-
Double-click the Physics Asset to open the Physics Asset Editor.
-
Under the Windows menu, select Profiles; the Profiles window should appear as a docked tab.
-
Add a Profile using the New button on the Constraints Profiles section, and set its name (in the image below we've named it
DocsConstraintProfile).
-
Select the Physics Constraint you want to include in your new Constraint Profile in the Skeleton Tree panel, the Physics Graph panel, or the Viewport.
To see Constraints in the Skeleton Tree panel, select Show Constraints in the Options dropdown menu.
-
Press the Assign button in the Profiles panel.
1 - Assign button 2 - Constraints selected in the Skeleton Tree panel 3 - Constraints selected in the Physics Graph panel 4 - Constraints selected in the Viewport
-
Adjust the properties for the selected Physics Constraints.
-
Repeat steps 5-7 for all the Physics Constraints you want to add to the Constraint Profile.
You can select, assign, and edit the Properties of multiple Constraints simultaneously. You only need to edit them individually if you want their Properties to be different.
-
Save your Physics Asset using the Save button in the Physics Asset Editor.
You can edit an existing Constraints Profile by selecting it in the dropdown menu, then using Assign to add new Constraints, or using Unassign to remove existing Constraints.
Result
The Physics Asset now has a profile that can be called upon from Blueprint or C++ to change its Physical Constraint properties.
