| attr | Vertex data attribute to check for. |
bool Returns true if the data attribute is present in the mesh.
Checks if a specific vertex data attribute exists on this Mesh.
Most of possible mesh vertex data attributes are optional, for example a mesh might contain only vertex positions, normals and one UV coordinate. HasVertexAttribute check for these attributes will return true in that case, and will return false for all other attributes.
