Procedural wrinkled paper lamp cycles material I am not completely new to Blender, but I'm actually on a project of interior design visualization where I would like to create a material that would allow me turn any surface into this kind of paper lamp.

Its basically wrinkled paper extruding from the volume, never intersecting with each other, slightly opalescent, with a light source inside (which could obviously be another object).

I have no idea where to start from. I guess it should involve procedural material rather that using an image, but I'm not sure how to make the lines protrude neither how to generate them and be able to modify their parameters 

I'd be really grateful if someone could show a way into this problem. Cheers!
Ok, so here's what I could come up with. This is what I could achieve with materials only. Not good enough for closeups, but perhaps enough for far-off objects or to save resources.



With modelling I got to this. It's not perfect, couldn't figure out a way to automatically make them not intersect, but its a reasonable time/effort/fidelity ratio.



Star of with an Icosphere, subdivide it enough, for the desired level of detail, then add a Decimate modifier.



Apply the decimate modifier, enter Edit Mode and in Edge Selection Mode with the Random Select operator select any number of edges around 50% to 60%.

Bevel those edges, then extrude them outwards with Alt + E > Region (Vertex Normals).





Add a Subsurf modifier on top, and you are good to go. Material is the same as above without all the texture work.



Additionally you may use Proportional Edit with a Random falloff type, to scale all vertex outwards, and/or rotate them slightly, and give it a more irregular look. Use a fake loose vertex, placed at the center of the sphere, selected for scaling, then use the 3D Cursor as center of transform and increase the influence radius as necessary.
