3D World Building for Virtual Environments

This skill covers the principles and workflows for constructing immersive 3D environments in metaverse and VR contexts. It addresses terrain creation, architectural modeling, lighting design, asset pipelines, and optimization techniques specific to real-time virtual worlds that must support multi-user presence and interaction.

## Key Points

1. Heightmap generation
2. Texturing
3. Vegetation
4. Erosion and detail passes
1. Wayfinding      — Users must intuitively know where to go
2. Acoustic design — Spaces should feel like they sound right
3. Social zones    — Areas that encourage groups of 2-6 people
4. Sight lines     — Can users see other avatars from key positions?
5. Personal space  — Provide alcoves and edges, not just open fields
6. Spectacle       — At least one awe-inspiring vista or feature
- All modules share the same texel density (pixels per meter)
- UV islands align at module edges for seamless tiling
