Shortest node veins

Adding veins to an eyeball, using a shortest path node

Created a node setup that incorporates the shortest path node and an ico sphere to generate veins that can then be overlayed on top of an eyeball mesh, not perfect but gives an interesting result.

Things of note

• The value in the ‘Greater Than’ node is dependent / linked to the number of subdivisions set for the Ico Sphere, the more devisions the higher the number can be set, if you reduce the number of subdivisions you’ll need to make sure the Greater Than number is not higher than the new reduced number of verts (if it is the veins will not appear).

• Upper and Lower parts of the tree are pretty much identical, the reason for the duplication is to create a set of main veins (bottom) and a finer set of smaller veins (top), the differences are in the

  • noise settings

  • ico sphere sub-divisions

  • greater than values
