Unfortunately the recent 1.15.7 patch appears have rendered this and your other excellent Air Canada express liveries incompatible. The problem doesn't seem to stop there however, as when one of these 2 liveries are present in the community folder it affects ALL other third party Longitude liveries. The problem is one of missing paint surface effect textures, i.e., shine, reflectivity, pbr effects, etc., so that all Longitude liveries have the appearance of of flat/matte non-reflective surfaces. Very strange, I know, but it took me quite some time to isolate the problem. Once your liveries are removed from the community folder all other third party liveries work properly once again. Would appreciate your looking into this and correcting if possible. Obviously something has changed in the new default Longitude file structure that causes this problem ...through no fault of your own.

Excellent livery, crisp and precise. Thank you for sharing.
