@aldomanetti When I select one OBJ as ‘OBJ File for 3D Plugins Sequence’ as you do at 0:30, I am able to load the entire sequence of OBJ’s into After Effects as one footage asset containing the entire sequence.
Are you able to open the same OBJs in other software like Blender? If not, have you opened them in a text editor to see if they have this issue?
