Looking at the code regarding the crash

TGraphMessageType* Message = nullptr;

		SharedContext->MessageStack.TopMessage<TGraphMessageType>([&Message](TGraphMessageType& InMessage)
		{
			Message = &InMessage;
		});

Would suggest that AnimNodeBase is expecting information in it’s message stack
SharedContext->MessageStack.TopMessage but is not receiving anything

Do you have a proper connection setup between unreal and your other software (both seen as connected and transferring data?), is your firewall blocking the exchange of information?

In your case it’s failing to get the Message and returns a null pointer causing further parts of the system to cascade fail (surprised they didn’t add a null check)

thx for reply.
but can more expaline to me what i do exactly ?
what can i do ?

4

What are you connecting unreal to? Maya? Iphone face tracking? Optitrack plugin?

5

iphone facce tracking live link face
`

6

And you have the apple ar face livelink setup in the livelink panel with a green light indicator showing a good connection?
(sources configured)

7

i can capture sequence and record me face to unreal but when i put in the sequence my character head not moving(just lipsync) and when i disable bluprint or play sequence unreal will crash.

8

Sequencer is pretty brittle. It also has problems with unreal rigs. Have you tried baking out the animation after recording it?

9

hi siory for late . how can i bake my record?

10

In sequencer select the object => select actions (looks like a spanner / wrench icon) and there you can find bake transform.

11

ok when i bake my head is go to hiden :(((

12

why my head dont move and no rotate in sequncee?

13

Do you have a separate face track for you metahuman setup?

14

no i just conect my iphone to metahuman and chois livelink in bloprint for face and head
