Hi~
I make a test Cutscene like this, it’s work good in most times.
But still report some errors:

This PlayableGraph is invalid. It may have been deleted.

And then the Animator is not work.
Please fix this, thanks.

Hello,

Thanks for the report.
Please try opening up AnimatorTrack.cs and replace line #273 with this code:

1 2 3 4 5

if (graph.IsValid()){ graph.Destroy(); }

This change should prevent the error and handle it correctly. If the error ever appears again, please let me know.
Thank you.

Thanks for your reply, it’s working good now.
But report another error:

Hello,

Next version will be coming this week.
About the errors, can you please let me know WHEN these errors are happening?
I honestly have not encounter any of these while working with Slate.
What are you doing when these happen? Is there any way for me to reproduce these errors?

Please let me know.
Thanks!

Thanks for your reply.
I am sorry for I can’t give more infomations for now, because this is a temp test project..it’s happen very accidental, hard to descript the steps…

Thanks again.
