SetMesh(UIMesh)

public void SetMesh(in UIMesh mesh)

Parameters

mesh

UIMesh

Remarks

Atomic: all fields update together, so cross-field length invariants are guaranteed. Prefer this over per-slice setters when resizing the entire mesh.
Validation: every non-empty extras slice in 
mesh
must have length equal to 
mesh.vertices.Length
, AND its channel must be enabled on the panel's ExtraVertexChannels mask. 
mesh.indices.Length
must be a multiple of 3. If any check fails the call is rejected (this draw stays unchanged) and an error is logged.
Metadata (
renderType
, 
phase
, 
texture
, 
userData
) is preserved.
