I’m not sure of this… but yhis just happend to me.
I set the Viewport Top perpective
And the Viewport was comple black.
The distance was vey huge (a exponential number)
I was selecting several actors in the scene but it didn’t work (the camera did not focus the actor and the distance still huge)
After several attempts it finally worked
Is not the fist time this happen to me.
But is the first time i see this.
I was looking for information about this but it seem to have different reasons
¿Niagara?
¿Threads?
I think it could be related with the Top perspective of the view port (i’m not sure)
The exception only occurred once.
I don’t know how I can reproduce it. And the viewport top perspective is working now.
So… i have no idea.
If someone know what really the problem is let me know please.
Thank you so much!!
