This tool lets you create a hi-res, fully customizable eye in minutes. You can then export the eye to a modeling software, or project the details and use it to create a low poly eye. (This node only generates and colors the high poly though)
To install: It should be a directory like this? (mine's custom so it's different) just look for the otls file in the houdini18.0 file.
If the node loads in with the cornea covering the iris, set the 'Hide Cornea' Parameter to 1.
It's free because it's my first ever procedural model, and first ever procedural tool. so it's probably inefficient in some way. If you use it and enjoy it enough to donate, I appreciate it, but don't feel obligated.
It's well documented in the node structure itself, and the 'help' section in Type Properties has contact info! So if you make something with it please tag me everywhere you post it! I'd love to see it!
