Over the years, I have streamlined my workflow and flattened out speedbumps in Zbrush with custom tools. Now they're available to everyone! Ryan's Tools comes in 2 versions: Standard and Pro.
Get Standard for free (But please leave a donation if you can). Standard is for hobbyists and students. Not for commercial use. No Tech Support. No Extra Brushes or Custom Gizmo.
Get Pro for $20 (you can leave an extra donation if you like). Pro is for any individual or business that is making money with Zbrush. You must buy a license for each seat of Zbrush that you use it with. It also comes with my custom Gizmo and lots of my custom brushes. Additionally, it comes with tech support if you have trouble.
After purchase, download the version of Ryan's Tools for your version of Zbrush:
version 1.5 Works in Zbrush 2020 only
version 1.3 Works in Zbrush 2019 only
If you want to use the plugin in version 2018, you're stuck with version 1.2
