MAX 9 2-sided plane primitive

[owen072080]

Hi guys!

 

im having problems with max 9. all the primitives are all in forced 2-sided mode even though in the viewport config it is uncheck.

 

 

is this really the default setting for max 9? in max 8 it wasnt like this.

 

if this is the default, how do i turn this off? i want one sided polys.

 

i really need some clarifications on this guys. thanks
