How do I add a procedural confetti pattern to a plaster wall?

Question

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.

Answer 1

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.

Answer 2

This answer gives a basic polygon-distance-function, which can be used to make a polygon-shader. Here, it's slightly adapted to give inputs for sides and size:

.. and incorporated in a group which:

• Gives a UV-per-cell of a Voronoi buy subtracting 'Position' from the texture coordinate
• Scales the polygons in that UV by the N-sphere radius of a parallel Voronoi, to prevent clipping by the cells.

it outputs the polygon-mask and color sparately.

It can be used on its own for a non-overlapping scatter, or masked against another version of itself for overlaps:

With results like this:

( The polygons could have as many sides as you like)

Answer 3

I was making my own scene in Blender when I cam across this question and thought I'd give my own interpretation. Pretty much the same as Duarte, but with some real specific placement on the Color Ramp in 2022. idk.

Answer 4

The closest thing you can get with procedural textures alone is Cycles Voronoi texture set to Cells.

Run it through a Color Ramp node to control the output color,
