"Rapid Rig: Modular" takes all the functionality of "Rapid Rig: Advanced" and breaks it down to its core, then was built back up into something with incredible flexibility. If you want a character with 4 arms, two heads, 20 eyes, 14 fingers, 8 legs, etc. you can now achieve this with this very powerful and robust tool while having very similar functionality to Rapid Rig: Advanced.
You can build a rig from scratch, starting only with a ROOT and adding:
•Splines (splines, necks, tails)
•FK Chains (fingers, tails, spines, wings)
You can attach any of these to each other in any order you like. You can make assymetrical characters, humans, dogs, spiders, birds, centaurs, dragons. Almost any creature you can imagine, you can rig with these tools.
The script comes with some powerful presets to get you started on with rig to save you time.
All modules can be modified after creation. You can also clone, mirror, reattach, pin and re-color your modules.
If you are happy with your proxies, you can save them out to a text file which can be loaded into any scene.
You can also save the transform information of your proxies to load onto a different proxy rig that is not identical.
