Thank you very much!
So you mean that if I package the game with mac,that stuck will never happen?
I have spent some time looking into these warnings concerning widget,and the result is that these warnings sometimes appeared but sometimes not.However,the red error message shown above appeared everytime I start the game on my ios device.(Actually this error just appears for less than 1 second every time,so it’s a little difficlut for me to capture this screenshot…)I think these widgets are not the main cause.
Also,I never came across this red message in the previous ue4 build(such as 4.9 or earlier).Thus,I think this have something to do with the new UE4.10.
I found a thread posted by another person who had encountered exactly the same issue in the forum,here’s the link:Texture streaming error - Mobile - Epic Developer Community Forums
Thanks a lot!
