Blank project missing "add torque in radians" and other physics BP nodes

If I make a rolling ball project in 4.20, the pawn uses the “add torque in radians” node to move the ball.

If I make a blank project in 4.20, this node is missing - it’s not available in the BP graph and copy/pasting it fails.

What is UE4 doing wrong here / what do I enable to get physics BP bodes?

[EDIT] I’m an idiot and was trying to use the node in a construction script.
