Summary by CodeRabbit

• Refactor
  • Enhanced the resource allocation strategy for skinned mesh rendering to improve overall efficiency when handling complex mesh configurations with multiple joints and blend shapes. This optimization provides better support for devices with varying resource constraints and enables improved handling of edge cases in mesh rendering scenarios.

Walkthrough

A new static member _baseVertexUniformVectorCount is introduced to SkinnedMeshRenderer with a value of 48, replacing a hard-coded constant 44 in the calculation of remainUniformJointCount. This refactoring centralizes the uniform vector count logic for improved maintainability.

Changes

Cohort / File(s)	Summary
Static Member Extraction packages/core/src/mesh/SkinnedMeshRenderer.ts	Introduced static member _baseVertexUniformVectorCount (value: 48) and updated remainUniformJointCount calculation to use this constant instead of hard-coded value 44. Changes affect uniform vector availability determination for joint texture versus macro selection.

Poem

🐰 A number once hidden, now stands tall and true,
Forty-eight vectors, extracted anew,
No more magic numbers to confuse and perplex,
Clean code hops forward, what's next, what's next? ✨

🤖 Augment PR Summary

Summary: Extracts the base vertex-uniform-vector budget used for skinning into a shared constant and applies it in the joint-count calculation.
Changes: Adds SkinnedMeshRenderer._baseVertexUniformVectorCount (48) and uses it when computing how many joint matrices can fit in vertex uniforms to avoid unnecessary shader recompiles.

Using Math.ceil here can overestimate remainUniformJointCount when the available uniform-vector budget isn’t divisible by 4, which may make RENDERER_JOINTS_NUM exceed MAX_VERTEX_UNIFORM_VECTORS and cause shader compile failures on some devices. Consider rounding down instead of up so the computed joint limit always stays within the reported uniform budget.
