Does anyone know how to fix this?
Is is possible to have the Mary's Arcade Models on Blender and then be ported?

Does anyone know how I remove this stupid line from the animation? I tried going into the camera view before I rendered it but its still here. Any help?
It seems like Manora is so hard to port from Blender to SFM. I don't know what I'm doing that won't let her be ported.

Just curious would you all like to see my unfinished/ Cancelled/ unrelease sfm animation?
