Given this game's focus on realism, and taking inspiration from a number of Minecraft mods, I wanted to bring up a mod I find essential in most of my playthroughs these days, which I think it'd be really cool to try to emulate to an extent, or at least take some notes from it, because currently trees look a bit, for lack of a better term, plain.
The mod is Dynamic Trees, and it overhauls how trees generate and grow, with a focus on more realistic shapes and sizes. Some features include:
-Trunks that get thinner higher up
-Branches that extend and, well, branch
-Leaves that constantly grow, regrow, and change
-Trees growing from a small sapling over time into a full-sized tree naturally
-Trunks that can be over 1 block thick, but under 2x2 in size
-Trunks that can be under 1 block thick
-Falling tree physics (to an extent)
-Larger trees generating aboveground roots
-Branches being far quicker to break than trunks
-Tree disease/lack of nutrients from soil causing stunted growth and tree-death
-Saplings planting themselves when leaves naturally decay
-Trees growing taller to fight with other trees for more sunlight under the canopy
-Emergant forests that live, grow, and wane on their own
-Unique generation for each tree type
-Surprisingly minimal performance hit, even in Minecraft, for all the tree updates happening constantly in wooded areas
It makes trees gorgeous and vastly improves their generation, look, feel, and functionality.
I feel like this style of tree, and a lot of the functionality, would feel right at home in Vintage Story's more detailed look and mechanics!
I can even imagine thinner branches being affected by the wind... It would look beautiful-
Of course I'd suggest crediting Ferreusveritas if you were going to take inspiration from the mod.
