Modelling pollen 3d mesh I am kind of a noob in blender, who's trying to model a grain of pollen for an ai experiment. The pollen grain is this one:


And I don't know how to model that random wireframe that overlaps itself in blender, 'cause the blender wireframe modifier only lets me build a perfect wireframe with no overlapping. 

I'm not native speaker so maybe some words are incorrect. Thank you if you can help me.
I'm not sure about what you mean with the random wireframe overlapping. To make this object I think you should fake the texture rather than model it, I see at least 2 ways:


With a Noise node > Height of a Bump node > Normal of a Diffuse. Here I've even mixed 2 noises in a MixRGB to give a bit more complexity. I also added a Layer Weight at the end, if necessary.






You could also create a repeatable texture from your original image. Unwrap your object, in the 3D view / Texture Paint mode, use the Stencil brush to paint on your object with your texture, and again use this with a Bump node.
