Last week's video was about adding variety to foliage.
Here are three new videos that show something similar but at a larger scale. The first two show transitions from snowy terrain to green terrain. The last one goes from green to some kind of rocky desert.
Do not pay too much attention to the sound, you will hear chipping birds no matter if it is snow or desert.
I did some improvement on the LOD switches. They are still happening pretty much on your face, but in general should be smaller.
