How do you reccomend we work with large levels?

I'm trying to create a large level in ldtk (1600 x 900) and load them into my game however it seems to crash due to too many textures trying to load onto the GPU at once. I noticed that bevy_ecs_tilemap under the hood implements Frustum culling by default, but as I understand this doesn't apply to layered tiles.

thread 'Compute Task Pool (3)' panicked at 'wgpu error: Validation Error

Caused by:
    In Device::create_texture
      note: label = `texture_array`
    Dimension Z value 3128 exceeds the limit of 2048

I tried to load the LdtkWorldBundle with visibility: Visibility::Hidden, computed_visibility::HIDDEN but this had no effect. I'm assuming that the solution probably involves ray-casting from the camera onto the tiles and only rendering those in view?

Hi - This is because of a sort-of bug that was fixed recently: #183. You can use this fix now by patching in that branch in your Cargo.toml

[patch.crates-io]
bevy_ecs_ldtk = { git = "https://github.com/Trouv/bevy_ecs_ldtk", branch = "fix/smaller-cached-white-image" }

I will likely release a new version in the next week or so w/ this fix implemented.

Edit: There actually is another possibility that this is a problem w/ your tileset being too large for your current wgpu settings, or static hardware limitations. If you're still experiencing this issue after patching, try this too: #176 (comment)

Now you will need to depend on the main branch - since that branch has been merged (and deleted).

[patch.crates-io]
bevy_ecs_ldtk = { git = "https://github.com/Trouv/bevy_ecs_ldtk", branch = "main" }

This bug fix is now in bevy_ecs_ldtk 0.7. Does it resolve your issue?
