curtain system on triangle surface

[ismailgurkanbozkurt]

i want to add my custom curtain system panels to a mass face but it gives me this result. Is there any work around?

What result are you wanting? 

...do you want to replace the panels with another type?  

...select panels, unclip and pick another panel to replace them with.  Of course, only a System Panel will work if you haven't a Custom-Sized Panel to replace them with.

I see you are using a custom panel for the tilt effect.  If so, you need to use a curtain panel pattern base, not a curtain system.  Non-rectangular shapes in a curtain system only works with the system panel type.
