It’s definitely not difficult to implement. There’s two types of the Snow FX in the pack - one that is sort of a “point area of effect” that only places snow in a certain radius, and the other is a large cylinder that is bound to the player camera that fakes the effect of snow filling the scene. Check out the video at the link above to see it in action. Thanks for your interest!
Make sure you’ve downloaded our latest update. The pack doesn’t automatically stay up to date, unfortunately. So you’ll have to manually do so in your Vault. If that doesn’t work, would you mind sending us some screenshots of your scene or perhaps a video of the issue to “marketplace@supergeniusstudio.com?” Sorry about the trouble, we’ll get it figured out!
