• react-doctor/r3f-no-shadows-on-unsupported-light

  Use a directional, point, or spot light when the scene needs a shadow-casting light

  All repositories warning · 1 : warning in React projects
  No fix No autofix ↗
• react-doctor/r3f-no-state-in-pointer-move

  Keep pointer-move previews in Three.js refs or transient state and publish one semantic React update when the interaction commits

  All repositories warning · 1 : warning in React projects
  No fix No autofix ↗
• react-doctor/r3f-no-state-in-use-frame

  Mutate Three.js refs or an external transient store inside useFrame; reserve React state for guarded, infrequent transitions

  All repositories warning · 1 : warning in React projects
  No fix No autofix ↗
• react-doctor/r3f-no-sync-readback-in-use-frame

  Move readback to a discrete or serialized async path and reuse the latest completed result during frames

  All repositories warning · 1 : warning in React projects
  No fix No autofix ↗
• react-doctor/r3f-no-unstable-args

  Keep reference-valued constructor arguments stable with module scope or useMemo so React Three Fiber does not reconstruct and dispose the Three.js object on a later render

  All repositories warning · 1 : warning in React projects
  No fix No autofix ↗
• react-doctor/r3f-no-use-frame-dependency-array

  Remove the dependency array. Pass a numeric render priority on R3F v9, or supported scheduling options on R3F v10

  All repositories warning · 1 : warning in React projects
  No fix No autofix ↗
• react-doctor/r3f-prefer-gpu-instanced-animation

  Move repeated per-instance transform motion into instanced attributes, a vertex shader, or GPU simulation

  All repositories warning · 1 : warning in React projects
  No fix No autofix ↗
• react-doctor/r3f-prefer-gpu-position-animation

  Animate repeated vertex or particle positions in a vertex shader, instanced attribute, or GPU simulation instead of rewriting them on the CPU every frame

  All repositories warning · 1 : warning in React projects
  No fix No autofix ↗
• react-doctor/r3f-prefer-instanced-mesh

  Render repeated meshes that share geometry and material with <instancedMesh> so they can use one draw call

  All repositories warning · 1 : warning in React projects
  No fix No autofix ↗
• react-doctor/r3f-prefer-use-loader

  Load render resources with R3F useLoader so Suspense caching can deduplicate them and a parent error boundary can surface failures

  All repositories warning · 1 : warning in React projects
  No fix No autofix ↗
• react-doctor/r3f-require-animation-mixer-update

  Call mixer.update(delta) from useFrame after starting mixer actions

  All repositories error · 1 : error in React projects
  No fix No autofix ↗
• react-doctor/r3f-require-data-texture-update

  Set texture.needsUpdate to true after changing data-texture pixels

  All repositories error · 1 : error in React projects
  No fix No autofix ↗
• react-doctor/r3f-require-dynamic-buffer-usage

  Set usage={DynamicDrawUsage} on buffer attributes uploaded from useFrame

  All repositories warning · 1 : warning in React projects
  No fix No autofix ↗
• react-doctor/r3f-require-environment-for-metal

  Provide scene environment lighting or an envMap for strongly metallic standard and physical materials

  All repositories warning · 1 : warning in React projects
  No fix No autofix ↗
• react-doctor/r3f-require-frame-delta

  Scale incremental transforms and interpolation by useFrame delta, use delta-aware damping, or assign from absolute time

  All repositories warning · 1 : warning in React projects
  No fix No autofix ↗
• react-doctor/r3f-require-global-effect-cleanup

  Register addEffect, addAfterEffect, and addTail from an effect and return the exact disposer so remounts do not retain global render-loop callbacks

  All repositories warning · 1 : warning in React projects
  No fix No autofix ↗
• react-doctor/r3f-require-instanced-buffer-update

  After setMatrixAt, setColorAt, or setMorphAt, set the matching instance buffer's needsUpdate flag to true

  All repositories error · 1 : error in React projects
  No fix No autofix ↗
• react-doctor/r3f-require-lighting-for-pbr

  Add a light, scene environment, material envMap, lightMap, or intentional emissive source for PBR materials

  All repositories warning · 1 : warning in React projects
  No fix No autofix ↗
• react-doctor/r3f-require-lit-material-normals

  Attach a normal BufferAttribute or compute vertex normals before applying a normal map to custom geometry

  All repositories error · 1 : error in React projects
  No fix No autofix ↗
• react-doctor/r3f-require-owned-texture-cleanup

  No fix No autofix ↗
• react-doctor/r3f-require-render-target-reset

  Call gl.setRenderTarget(null) on every useFrame path after rendering to an offscreen target

  All repositories error · 1 : error in React projects
  No fix No autofix ↗
• react-doctor/r3f-require-render-with-positive-priority

  Render the scene or composer from the positive-priority useFrame subscription, or use a non-positive priority to keep automatic rendering enabled

  All repositories warning · 1 : warning in React projects
  No fix No autofix ↗
• react-doctor/r3f-require-root-unmount

  Unmount component-owned R3F roots in React cleanup, or return an exact disposer that unmounts the root
