Struct bevy_internal::render::prelude::MorphWeights

pub struct MorphWeights { /* private fields */ }

Controls the morph targets for all child Handle<Mesh> entities. In most cases, MorphWeights should be considered the “source of truth” when writing morph targets for meshes. However you can choose to write child MeshMorphWeights if your situation requires more granularity. Just note that if you set MorphWeights, it will overwrite child MeshMorphWeights values.

This exists because Bevy’s Mesh corresponds to a single surface / material, whereas morph targets as defined in the GLTF spec exist on “multi-primitive meshes” (where each primitive is its own surface with its own material). Therefore in Bevy MorphWeights an a parent entity are the “canonical weights” from a GLTF perspective, which then synchronized to child Handle<Mesh> / MeshMorphWeights (which correspond to “primitives” / “surfaces” from a GLTF perspective).

Add this to the parent of one or more Entities with a Handle<Mesh> with a MeshMorphWeights.

Implementations

impl MorphWeights

pub fn new( weights: Vec<f32>, first_mesh: Option<Handle<Mesh>> ) -> Result<MorphWeights, MorphBuildError>

pub fn first_mesh(&self) -> Option<&Handle<Mesh>>

The first child Handle<Mesh> primitive controlled by these weights. This can be used to look up metadata information such as Mesh::morph_target_names.

pub fn weights(&self) -> &[f32]
