# Objective Fixes #16525 Fixes #19710 ## Solution Not allocating a mesh if it is empty. ## Testing I tested using the following minimum repro from #16525 ```rust use bevy::{asset::RenderAssetUsages, prelude::*, render::mesh::PrimitiveTopology}; fn main() { App::new() .add_plugins(DefaultPlugins) .add_systems(Startup, setup) .run(); } fn setup( mut commands: Commands, mut meshes: ResMut<Assets<Mesh>>, mut materials: ResMut<Assets<ColorMaterial>>, ) { commands.spawn(Camera2d); let mesh = Mesh::new( PrimitiveTopology::TriangleList, RenderAssetUsages::default(), ); commands.spawn(( Mesh2d(meshes.add(mesh)), MeshMaterial2d(materials.add(Color::hsl(180.0, 0.95, 0.7))), )); } ``` I was able to test on webgl2 and windows native and the issue seems to be resolved. I am not familiar with how mesh rendering works and feel like just skipping meshes should cause issues but I did not notice any. |
