Creating Conditional Actions

Conditional Action

Select a group you want to affect by Condition Action from the Group section (in our case, it is Light Transform).

Then:

1. Select the Condition as the Equal

2. Define an Input Value

3. Drag & drop your Group to the Conditional Actions panel

4. Repeat the same process for different conditions and adjust the values

"Else" Condition

• Select the Else condition

• Drag & drop your Group to the Conditional Actions panel

• Optionally define new property values

Deleting a single item from any section (Controller, Behaviour, etc.) sometimes crashes the Unreal Engine. For this issue, please refer to https://issues.unrealengine.com/

Workaround: You can remove all items and then add them again.
