-- Il faudrait peut Ãªtre faire un lÃ©ger shift vers le bas pour que l'on ne voit pas la texture de l'eau initialement. (le 0 de la simulation vaut 0.001 dans les donnÃ©es)
-- Le cube reset est bas et petit en VR
-- Avec le bug de reset sur l'eau, est ce qu'il serait possible d'associer un des boutons des manettes du Quest Ã  l'action "Recharger la page" ? Comme la simulation est courte, cela permettrait de rafraÃ®chir facilement.
-
-Extra
-- Couleurs batiments/toits plus neutres
-
-Problematique
-- Au niveau du sol, en dÃ©but de simulation, on a un effet de scintillement entre le sol blanc et l'eau qui peut Ãªtre dÃ©sagrÃ©able.
-- J'ai un utilisateur qui m'a demandÃ© si c'Ã©tait possible d'animer un peu la texture de l'eau
-
-A discuter
-- Il y a un bug avec la position du modÃ¨le 3D et des bÃ¢timents procÃ©duraux (au moins sur la Ruelle) cf capture
-Etonnant car arbres OK?
-
-A reparer
-- faire le test in_situ quand la localisation sera gere
-- Il faut un peu revoir les hot-spots dans le quartier des Baquets, certains sont dans des jardins et on peut se retrouver enferme
