Bevy: How to Load Multiple Texture Atlases

So I'm currently working with Bevy to make a game with a style similar to that of Octopath Traveler. I'm using the bevy_sprite3d crate to render sprites in the 3D space. I'm currently working on writing the code for the battle scene of my JRPG. However, whenever I try to load multiple sprites into the scene, it gives me the following error:

error[B0002]: ResMut<bevy_asset::assets::Assets<bevy_sprite::texture_atlas::TextureAtlas>> in system load_sprites conflicts with a previous ResMut<bevy_asset::assets::Assets<bevy_sprite::texture_atlas::TextureAtlas>> access. Consider removing the duplicate access.

Am I doing this wrong? Is there a better way to load multiple texture atlases for the different entities in my battle scene? Thanks in advance!

- Hello! So I ended up fixing this issue with sprite loading and figured out how to load multiple sprites in the scene. It turns out that I can't load the images and then spawn in the sprite objs in the same function because of Rust rules 🤷
  Anyhow, I am having a different issue now, and I've made a new post about it here.
You should probably ask over here as well: https://github.com/FraserLee/bevy_sprite3d/issues I havent used this library before but I might take a look once Im out of the bath
- ok so I'm out of the bath.
  rust
  
  #[derive(SystemParam)] pub struct Sprite3dParams<'w, 's> { pub meshes : ResMut<'w, Assets<Mesh>>, pub materials : ResMut<'w, Assets<StandardMaterial>>, pub images : ResMut<'w, Assets<Image>>, pub atlases : ResMut<'w, Assets<TextureAtlas>>, pub sr : ResMut<'w, Sprite3dRes>, #[system_param(ignore)] marker: PhantomData<&'s usize>, }
  It seems like Sprite3dParams is already accessing Assets<TextureAtlas> which is why you get the the error. So you need to either remove texture_atlases or sprite_params. in your system.
  have you looked at this example? I won't be much help sorry :(
