This is the field manual for VRChat world building, and it opens with what matters most: a table of disasters you must avoid. The "NEVER List" alone is worth the read,11 ways to silently kill your frame rate or trap players in respawn loops, explained with actual consequences instead of vague warnings. It's organized around decision points (Quest support yes/no, player count, lighting approach) and tells you which reference files to load for each task so you're not drowning in docs. The Quest First philosophy runs through everything: bake your lights, turn mirrors off by default, and treat Quest limits as the baseline. If you're placing VRC_SceneDescriptor or debugging why players fall through floors, this gets you to the fix without guessing.
