Since I installed ArcGIS Earth 1.8 I cannot view any textured slpk files. Going back to 1.6.1 solved my problem.
I can not reproduce this issue. Are you able to share the data or any screenshots? If feasible, please send to email@example.com. The team will check this issue asap.
ArcGIS Earth V1.9 is live and includes some enhancements for Scene Layer. Could you help to check if your issue can be addressed in V1.9? Thanks.
You can get ArcGIS Earth V1.9 from ArcGIS Earth | ArcGIS
