If you want to see snow under Minecraft trees, then download the Snow Under Trees Mod 1.16.4/1.15.2/1.14.4! Trees in the game now become a snowy area.
The author said he created this mod throughout the MMD WinterJam 2019. His purpose is to make the Minecraft world more meaningful in winter. Trees now feature a lot of snow. You will see snow when you create new chunks. However, you need to keep in mind that only biomes that are cold enough will have snow. For other hot biomes, the trees will not be snowy. The mod does not have an influence on the common forests. Also, only the mod works only in the modded biomes.
The mod gives you a tool to add snow under the trees. When you create a new world, it will make a tree there and the tree will have snow under it. However, it will not fill it again. You can use this tool as much as you want. Here are some configurable options available in the mod:
enable_biome_feature: This allows you to disable snow from appearing under trees when you make new chunks.
enable_when_snowing: Snow will not appear under trees when it’s snowing in the world.
filtered_biomes: Some biomes will not be influenced by this mod.
Feel free to use Snow Under Trees in your favorite modpacks. Make sure you give credit to the author of the mod. You have to download and install Minecraft Forge so the mod can run.
