In Unreal Engine, the “Cast Shadow” property can be accessed via Blueprint by using the “Set Cast Shadow” node.

Here are the steps to do this:

1. In your Blueprint, add a “Set Cast Shadow” node.
2. Connect the output of your Niagara System to the “In Particles” input of the “Set Cast Shadow” node.
3. Add a “True” value node and connect it to the “Cast Shadow” input of the “Set Cast Shadows” node.

This will set the “Cast Shadows” property of your Niagara System to “True” by default every time it is activated.
