Method Migration
The following public methods were renamed because an unprefixed, parameterless public UdonSharp method remains callable through legacy network dispatch:
| Before | After |
|---|---|
ForceDropPickup | _ForceDropPickup |
IsHeld | _IsHeld |
IsOccupied | _IsOccupied |
StopSound | _StopSound |
SlowUpdate | _SlowUpdate |
Update Inspector event strings, SendCustomEvent* calls, delayed events and
nameof(...) expressions, and cross-behaviour calls. Compatibility aliases are
not provided because an old unprefixed alias would restore the same legacy network exposure.
Common Mistakes (NEVER List)
These cause silent world failures, performance disasters, or Quest incompatibility:
| # | NEVER do this | Why it hurts | Use instead |
|---|---|---|---|
| 1 | Enable Mirror by default (active on world join) | A mirror adds another costly scene render; the impact depends on view, scene, resolution, and device | Default Mirror OFF; add a player-controlled toggle and profile each target device |
| 2 | Use realtime directional lights with real-time shadows without profiling | Realtime shadow cost varies with scene geometry, view, and target device and can dominate frame time on Android | Prefer baked lightmaps + light probes; profile the target device before keeping any realtime shadows |
| 3 | Set Respawn Height at or above the world floor | Player respawns → falls → respawns again → infinite loop; players cannot recover | Set to an unreachable depth (e.g., floor at Y=0 → Respawn at Y=-100) |
| 4 | Skip "Setup Layers for VRChat" on a new project | Layer collision matrix is wrong by default — players walk through walls, Pickups clip floors | Run VRChat SDK > Builder > "Setup Layers for VRChat" before placing any colliders |
| 5 | Enable Post-Processing without an Android build profile | Post-processing is disabled at runtime on Android, so the authored effect will not appear and unnecessary resources can still enlarge the build | Use a separate Android build profile with post-processing removed |
| 6 | Place more than 2 active video players simultaneously | Each player adds significant decoding overhead; running >2 simultaneously is a common cause of frame drops and audio issues in practice | Disable extra players at scene start; activate only the currently playing one |
| 7 | Use Cloth on Android, or add many Unity Constraints without profiling | Cloth is disabled on Android. Unity Constraints are permitted in worlds, but overuse can significantly affect performance | Remove Cloth from the Android build; prefer VRC Constraints for new work and profile any constraint-heavy setup |
| 8 | Upload without completing a lightmap bake | Realtime GI adds substantial scene-dependent render cost and is unsuitable as an unmeasured fallback on Android | Bake lights before upload, then verify the result on the target device |
| 9 | Place player walkable surfaces on Default layer (0) | Collision matrix is wrong by default — avatar physics collision is unreliable; players may clip through geometry | Use Environment (layer 11) for all walkable geometry, walls, and floors |
| 10 | Use very high lightmap resolution for large areas without profiling | Texture memory can spike significantly at high resolutions; a common cause of OOM crashes on mobile headsets | Start at 10-20 texels/unit (PC) / 5-10 (Quest) as a practical guideline; profile VRAM and adjust — official guidance says "keep lightmap resolution low" for Quest |
| 11 | Add VRC_UIShape to a Screen Space or Overlay Canvas | VRC_UIShape requires World Space Canvas; other modes throw a runtime Unity error in VRChat — the UI renders visually but is not interactive, with no visible error to the world builder | Set Canvas > Render Mode to World Space before adding VRC_UIShape |

Before Starting a New World — Design Decisions
These decisions shape every downstream choice. Make them first, before placing any component.
| Decision | Options | Implication |
|---|---|---|
| Quest required? | Yes / No | Yes → Quest First philosophy applies from day 0, not as a retrofit |
| Expected player count? | 1–8 / 9–40 / 40+ | Affects spawn count, mirror policy, max video players |
| Primary interaction? | Grab (Pickup) / Sit (Station) / Watch (Video) / Explore | Determines which SDK components are mandatory |
| Lighting approach? | Baked / Mixed / Realtime | Prefer baked lighting on Android; profile each target device before keeping realtime lighting or shadows |
| Networked objects? | None / Physics (Pickup+ObjectSync) / State (UdonSynced) | Determines sync architecture before Udon scripting begins |
Design Philosophy: Quest First
If the world must run on Android, decide those constraints before tuning the PC build. Test each target separately.
Android headsets have mobile CPU, GPU, memory, and thermal budgets that differ from PC and vary by device:
- GPU: Realtime lights, shadows, overdraw, and complex shaders can dominate frame time
- Memory: Textures and lightmaps share limited system memory with the client
- Thermals: Sustained load can reduce available performance during a session
Measure each target device independently; PC results do not establish Android performance, and a single-client Quest result does not predict a particular PC frame rate. Use the Unity Profiler and the official Android content optimization guide before publishing.
NEVER optimize exclusively for PC with "Quest support added later" — by that point, lighting, materials, and mesh density are all locked to PC quality, and the Quest port requires rebuilding everything.
Quest First Cascade — when Quest is required, every downstream decision inherits constraints:
Quest required? → Yes
├── Shaders: World shaders are unrestricted; prefer mobile-compatible shaders and profile custom ones
├── Lighting: Baked by default; retain realtime effects only after target-device profiling
├── Geometry: Budget approximately 250,000 triangles for the whole world; reduce further when profiling calls for it
├── Materials: Minimize unique materials and draw calls; no fixed world upload limit is documented
├── Audio: Mono, compressed, limited concurrent sources
└── Physics: Simplified colliders, minimal Rigidbodies
