Rotating props without PropRotatingParams mod (based on a script by Ronyx69) - Single rotating part

prop-rotating-single.cs

// Warning: Do not save vehicles after running this script without a game restart!

// Prop Rotating Script
// Control rotation axis, pivot and speed.

// Run in asset editor and see effects in real time.

// Animated faces must be vertex painted black! The rest reimains white.
// Google how to do vertex color painting in your 3d software of choice!

// The LODs are not rotating, they are like regular props.

var speed = 60.0f; // rotations per minute
