ok so I'm out of the bath.
#[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 :(
They still put drm in the games sold on their store though.
