Mise à jour Unreal Engine 5.4.3

Le Hotfix Unreal Engine 5.4.3 est en ligne et règle de nombreux problèmes de la version 5.4.

Les équipes d’Epic Games ont corrigé beaucoup de bugs dans cette version avec notamment le problème de ghosting sur les landscapes sans Nanite qui est toujours présent mais il suffit d’activer Nanite pour qu’il soit résolu; le problème des textures en lowRes ou floues; les crashs d’UE5 qui plante lors du chargement/traitement de certains assets; le problème du build des niveaux qui se bloquent lors de la diffusion des textures; et les problèmes des performances très instables avec un gain de l’ordre de +/-30%.

La mise à jour Unreal Engine 5.4.3 est donc disponible, voici la liste complète des correctifs :
