My version is Tourweaver6.5.00 111121.
I add two scenes in the tour and one named A and the other one named a Chinese character 05XX.
Then i add lens flare for both secen.
But when i preview it .
The A scene lens flare works very well ,while the 05XX sence does not work.
So the reason is the name of the secne.
Please try the English word or letter as your scene name but not use special characters.
