Many many thanks Cyrille, Max and Ypatios,

two triangles was the first attempt i made to build the flag
(many thank for remember me the numbers of branchs).

I can not use a set of more simple polygon to create the star because, 
in a second step of work every star mast  came
in front of the stage and show some photos and video of kids 
([pix_texture]), in this case every single shape cam with the same 
texture. The effect is nice but the content is not very clear.

A way to sum (grouping) the triangles ?

or is better the follows steps ?

1) texture a star (jpeg etc.) on a square
2) play with the alpha of result
3) texture the shape resultant with photo and video

Any help and/or example will be great
p.s. apologize my poor english
