# Objective - Custom render passes, or future passes in the engine (such as https://github.com/bevyengine/bevy/pull/10164) need a better way to know and indicate to the core passes whether the view color/depth/prepass attachments have been cleared or not yet this frame, to know if they should clear it themselves or load it. ## Solution - For all render targets (depth textures, shadow textures, prepass textures, main textures) use an atomic bool to track whether or not each texture has been cleared this frame. Abstracted away in the new ColorAttachment and DepthAttachment wrappers. --- ## Changelog - Changed `ViewTarget::get_color_attachment()`, removed arguments. - Changed `ViewTarget::get_unsampled_color_attachment()`, removed arguments. - Removed `Camera3d::clear_color`. - Removed `Camera2d::clear_color`. - Added `Camera::clear_color`. - Added `ExtractedCamera::clear_color`. - Added `ColorAttachment` and `DepthAttachment` wrappers. - Moved `ClearColor` and `ClearColorConfig` from `bevy::core_pipeline::clear_color` to `bevy::render::camera`. - Core render passes now track when a texture is first bound as an attachment in order to decide whether to clear or load it. ## Migration Guide - Remove arguments to `ViewTarget::get_color_attachment()` and `ViewTarget::get_unsampled_color_attachment()`. - Configure clear color on `Camera` instead of on `Camera3d` and `Camera2d`. - Moved `ClearColor` and `ClearColorConfig` from `bevy::core_pipeline::clear_color` to `bevy::render::camera`. - `ViewDepthTexture` must now be created via the `new()` method --------- Co-authored-by: vero <email@atlasdostal.com> Co-authored-by: Alice Cecile <alice.i.cecile@gmail.com>
