# Objective Make it obvious why stuff renders pink when rendering stuff with bevy with `default_features = false` and bevy's default tonemapper (TonyMcMapFace, it requires a LUT which requires the `tonemapping_luts`, `ktx2`, and `zstd` features). Not sure if this should be considered as fixing these issues, but in my previous PR (https://github.com/bevyengine/bevy/pull/9073, and old discussions on discord that I only somewhat remember) it seemed like we didn't want to make ktx2 and zstd required features for bevy_core_pipeline. Related https://github.com/bevyengine/bevy/issues/9179 Related https://github.com/bevyengine/bevy/issues/9098 ## Solution This logs an error when a LUT based tonemapper is used without the `tonemapping_luts` feature enabled, and cleans up the default features a bit (`tonemapping_luts` now includes the `ktx2` and `zstd` features, since it panics without them). Another solution would be to fall back to a non-lut based tonemapper, but I don't like this solution as then it's not explicitly clear to users why eg. a library example renders differently than a normal bevy app (if the library forgot the `tonemapping_luts` feature). I did remove the `ktx2` and `zstd` features from the list of default features in Cargo.toml, as I don't believe anything else currently in bevy relies on them (or at least searching through every hit for `ktx2` and `zstd` didn't show anything except loading an environment map in some examples), and they still show up in the `cargo_features` doc as default features. --- ## Changelog - The `tonemapping_luts` feature now includes both the `ktx2` and `zstd` features to avoid a panic when the `tonemapping_luts` feature was enable without both the `ktx2` and `zstd` feature enabled. |
