A small Christmas-themed 3D demo in Defold. The main goal is to share my 3D experience and tool for Defold

Highlights

Character animation pipeline: defmesh fork + Blender Python exporter, GPU skinning with tracks baked into a texture, and a custom fp16 binary mesh format to reduce asset size.
3D character controller: movement, jump, and extra step-up force for small obstacles (stairs, stones).
In-game 3D editor using ImGui: create objects, edit properties, move/rotate/scale.
ECS for 3D world setup.
Forward+ lighting with shadows and fog.
