You're absolutely right and I've been struggling for years now to find a balance between tree scale and mountain scale. Big trees make mountains look small but small trees look goofy compared to the player. I think your solution is the right one, in making trees shorter as you increase in elevation. Right now, I'm using trees made by other people and there's not that much variation in height, so in the future I'm just going to have to build my own set of trees to use. Thank you for the compliment on the transition, I worked really hard on making that look right.

Go for it!
