# Objective
Alternative to #24004.
https://github.com/bevyengine/bevy/pull/23288 adds ltc luts for rect
light support which implicitly requires `bevy_image/ktx2` and
`bevy_image/zstd` otherwise loading ltc luts will panic.
We either accept to always enable area light supoort (#24004), or add a
feature to opt out it (this PR).
## Solution
Gate ltc luts behind a feature and merge them to a texture array.
## Testing
`rect_light` example works.
