The trees are entirely procedural, built using Geometry Nodes in Blender 3.0 with a number of exposed parameters for easy tweaking, and the text effect is dynamic too (though it relies on a base curve for the actual letter shapes). Should be pretty easy to update it with whatever message you’d like, just download the project file, update the curves, and enjoy. Merry Christmas!
