We tried to model the Green screen in Blender but somehow we dont have the « wireframe » mode to visualize it inside aximmetry, and for some reason it looks like its not showing after all.

I have used this tutorial : https://youtu.be/emUsjKpjlkc?feature=shared

my mesh is 1 part, 1 UV (not really clean but no overlapping faces and so on).

I wondered it may be origin issue but i just cant monitor anything because the wireframe mode he is using in the tutorial isnt there with my latest version of the software anymore.

This is preventing us to do dynamic clean plate with an iPhone, any help would be appreciated
