How do I add a procedural confetti pattern to a plaster wall? Okay,I'm gonna ask this again and I'm gonna be more specific. Do you remember in FNaF how you see a triangle shaped confetti texture on the walls? The clearest view of it is in the West Hall as displayed in the image below. Well,I am trying to find out if this can be done procedurally or if I have to use an image texture for it.



Can someone please help me out? If you can,I'll give you a big,fat thumbs up and I'll check your question as the answer.
You will need to do this with a texture. (I have created a seamless texture for you) I don't believe there are triangle shapes with nodes, so I dont think this can be done procedural. 

Here is the Link for a seamless 4K texture I made real quick in PS. 

This one below is just a reference of what it looks like. 



Hope this helps.
