Steps to Reproduce:
Place down a powder snow block
Hold a spyglass
Use the spyglass
Step into the powder snow
Observed Results:
The spyglass overlay will appear, then the freezing overlay will appear very quickly and unnaturally at full opacity.
Expected Results:
The freezing overlay's opacity would slowly ease into a higher value over time.
