# Objective - bevy_render is gargantuan ## Solution - Split out bevy_mesh ## Testing - Ran some examples, everything looks fine ## Migration Guide `bevy_render::mesh::morph::inherit_weights` is now `bevy_render::mesh::inherit_weights` if you were using `Mesh::compute_aabb`, you will need to `use bevy_render::mesh::MeshAabb;` now --------- Co-authored-by: Joona Aalto <jondolf.dev@gmail.com>
