Marco Buono dc1f76d9a2 Fix handling of double_sided for normal maps (#10326) ... # Objective Right now, we flip the `world_normal` in response to `double_sided && !is_front`, however when calculating `N` from tangents and the normal map, we don't flip the normal read from the normal map, which produces extremely weird results. ## Solution - Pass `double_sided` and `is_front` flags to the `apply_normal_mapping()` function and use them to conditionally flip `Nt` ## Comparison Note: These are from a custom scene running with the `transmission` branch, (#8015) I noticed lighting got pretty weird for the back side of translucent `double_sided` materials whenever I added a normal map. ### Before <img width="1392" alt="Screenshot 2023-10-31 at 01 26 06" src="https://github.com/bevyengine/bevy/assets/418473/d5f8c9c3-aca1-4c2f-854d-f0d0fd2fb19a"> ### After <img width="1392" alt="Screenshot 2023-10-31 at 01 25 42" src="https://github.com/bevyengine/bevy/assets/418473/fa0e1aa2-19ad-4c27-bb08-37299d97971c"> --- ## Changelog - Fixed a bug where `StandardMaterial::double_sided` would interact incorrectly with normal maps, producing broken results.		2023-10-31 09:44:40 +00:00
