Red viewfinder on matinee's exports

Hi guys,

I’m producing an ArchiViz video with UE 4.13. I have spent whole yesterday exporting PNG sequences via Matinee; today, looking closely, I found that every single png has a little red viewfinder in his center (!?!). :G
I haven’t had this problem with 4.12, does any of you have a clue of where this cross comes from?

Thank you!


Andrea, there will be a HUD blueprint somewhere in your content browser that is being activate when the level starts. Have a look in the level blueprints or character blueprint to see if there is a node activating it.
