# Objective Remove the limit of `RenderLayer` by using a growable mask using `SmallVec`. Changes adopted from @UkoeHB's initial PR here https://github.com/bevyengine/bevy/pull/12502 that contained additional changes related to propagating render layers. Changes ## Solution The main thing needed to unblock this is removing `RenderLayers` from our shader code. This primarily affects `DirectionalLight`. We are now computing a `skip` field on the CPU that is then used to skip the light in the shader. ## Testing Checked a variety of examples and did a quick benchmark on `many_cubes`. There were some existing problems identified during the development of the original pr (see: https://discord.com/channels/691052431525675048/1220477928605749340/1221190112939872347). This PR shouldn't change any existing behavior besides removing the layer limit (sans the comment in migration about `all` layers no longer being possible). --- ## Changelog Removed the limit on `RenderLayers` by using a growable bitset that only allocates when layers greater than 64 are used. ## Migration Guide - `RenderLayers::all()` no longer exists. Entities expecting to be visible on all layers, e.g. lights, should compute the active layers that are in use. --------- Co-authored-by: robtfm <50659922+robtfm@users.noreply.github.com> |
