We will be adding the ability to prevent an animation from looping in the future but in the mean time, you can workaround this by:

• Right click the current step name>then continue step.
• Create an event invocation referencing the new step.

Note

• Although this gets the desired end result, by essentially creating a new step, keeping the transforms of objects in the last frame, this may appear to clutter up the editor with multiple static steps.
