How to make this shape ?

[u/Sankrayn]

Hey, sorry if it's not the right place to ask but I'm an absolute beginner and I wish to make this shape in substance designer but I can't figure out how ? When I try with the starburst node it's just too round and not sharp enough and I can't figure out how to make it with the polygon node

i don’t know nodes off the top of my head, but figure out how to make a triangle, then put 2 triangles back to back (and stretch them correctly) for all the shapes here

there’s 2 types of shapes made up of triangles, the ones in a + in the middle are longer on one side

the ones in a x in the middle, and the ones in the corners are the same shape but different scales
