What's the Error? when attempting to spawn a sprite3d and upon calling bundle this line of code panics: let image_size = params.images.get(&self.image).unwrap().texture_descriptor.size; however bevy is able to load the image just fine. here's my full code.

use bevy::prelude::*;
use bevy_inspector_egui::quick::WorldInspectorPlugin;
use bevy_sprite3d::Sprite3d;
use bevy_sprite3d::*;
use std::sync::Mutex;
use kira::{
	manager::{
		AudioManager, AudioManagerSettings,
		backend::cpal::CpalBackend,
	},
	sound::streaming::{StreamingSoundData, StreamingSoundSettings},
};
#[derive(Resource)]
struct Epic
{
    manager: Mutex<AudioManager>
}

fn main() {
    let mut manager = Epic { manager: AudioManager::<CpalBackend>::new(AudioManagerSettings::default()).unwrap().into()};
    App::new()
        .insert_resource(manager)
        .add_plugins(DefaultPlugins)
        .add_plugin(Sprite3dPlugin)
        .add_plugin(WorldInspectorPlugin::new())
        .add_startup_system(setup)
        .run();
}

fn setup(mut manager: ResMut<Epic>, mut commands: Commands,  asset_server: Res<AssetServer>,  mut sprite_params : Sprite3dParams) 
{
    println!("do something");
    
    let sound_data = StreamingSoundData::from_file("assets/audio/isle.mp3", StreamingSoundSettings::default()).unwrap();

    manager.manager.lock().unwrap().play(sound_data).unwrap();
    commands.spawn(Camera3dBundle {
        transform: Transform::from_xyz(0.0, 0.0, 0.0),
        ..default()
    });
    let image = asset_server.load("bf.png");
    
    commands.spawn(Sprite3d
    {
        image: image,
        unlit: true,
        ..default()
    }.bundle(&mut sprite_params));
}

Setup: bevy 0.10 + bevy_sprite3d Issue: A part of character sprite disappears at some positions

The character and all tiles are individual 3d sprites. The tiles are rotated PI/2 along x axis to make a flat floor. (as shown in the video, the floor is indeed flat)

The character moves along x/z and after passing half of the tile, the lower part of the character disappears. This happens for every single tile.

Other than this issue, everything else works fine, including lighting and shadows.

it seems to be turned into a PbrBundle so i cant figure out how to access the index. Id like to achieve something like https://bevyengine.org/examples/2d/sprite-sheet/

There's an open bevy issue for this at https://github.com/bevyengine/bevy/issues/4372, seems like the most straight-forward path would be to go in and resolve this in the engine. Barring that, there are a few more patch-style fixes we could try:

• Manually creating a far simpler interim shader for sprites, possibly at the cost of PBR
• Analytically modifying mesh shape to fit the contours of a non-transparent sprite
  • This might have some side-benefits in collision, mouse picking, etc.

Will look into this more later.
