A fast search shows (few) posts with the same problem.

This one (  https://forums.unrealengine.com/t/ensure-condition-failed-on-level-load/509428  ) says that it was solved by taking care of the default pawn (whatever that means).

Thank you for responding and providing a link Buffo. However, it doesn't give me enough information for a solution. Also, I forgot to mention that I am using the ActorSequence inside an actor blueprint.

Thanks!

Hi,

You probably would need to cook with Epic's UE with the right target to replicate this issue there.

You could try using a Level Sequence to animate the FBXs if you are not already doing that.
Also, can you show the relevant blueprint and Actor Sequence, that could greatly help us to figure out what is going wrong.

Warmest regards,

Thank you for your response.

This is basically my blueprint. That's it.

I can't think of any reason for it to cause some errors, other than this warning:

Any solution would be helpful if it doesn't require recompiling unreal engine.

Thank you

Hi,

Using experimental plugins can lead to all kinds of issues.

Did you rebuild the lighting like it is said here?: https://docs.unrealengine.com/5.2/en-US/sequencer-blueprint-component-in-unreal-engine/
You should actually Build All Levels:

Are you sure you really need an Actor Sequence Component, can't you do it with a Level Sequence for example?

Warmest regards,
