This is the RiderTHiCC Gen3 resources rig for the bodies I offer: https://www.xivmodarchive.com/modid/32341. It is meant to be added to an existing Gen3 rig (like Titan's Gen3 Rig), or can be used alone. Contains all body upscales made by me, with some Tight & Firm Gen3 meshes (it does NOT contain all the meshes from Tight & Firm Gen3 Rig) for usage as base sizes when upscaling.
Instructions and usage in text file at link, and this rig is based of the Tight & Firm Gen3 Rig. Contains a 3DS Max 2019 rig (compatible with that or newer) and a Blender file.
If you need troubleshooting help, first check the NOTES+INSTRUCTIONS.txt file, or ask in your modding Discord(s) about the problem you are facing when installing this mod, before writing to me directly.
