Steps:

1. Start by renaming the collection to "LI-barrel-blue" (Library Instance).
2. Split the viewport and make an Asset Browser window.
3. Go to the Environment catalog and search for Pole. Drag one of the poles into the viewport onto the snow patch.
4. Select the snow patch and assign the snow material from the pole. Enter Edit Mode > U > Unwrap Angle Based. (Make sure to apply scale Ctrl + A before unwrapping).
5. Select the pole, press F3 > Make Instances Real. Remove the collision object and empties.
6. Go to the Object Data Properties (green downward pointing triangle) and break the link. We can now enter Edit Mode.
7. Separate the snow patch of the pole L to select linked. Press P > Selection. Set the origin point of the snow patch, the W > Set Origin > Origin to Geometry.
8. Adjusted the pole length and move the snow patch on top of the pole.
