The Acheron Series includes many character base meshes, accessories and animations that use a single standard rig. Easily populate your project with exactly what you need. Visit the Acheron Series website: acheronseries3d.weebly.com/
If you want to get the most bang for you buck, this collection has everything you need to start filling your project with Acheron Series characters. A nice balanced set of races, Warrior and Villager outfits and Hair Styles. Each race comes with 16 palette swaps, the outfits have over 80 palette swaps, the hair styles have 100 built-in color swabs and all the color palettes are very easy to modify if you want to add your own.
(NOTE: Some of the races depicted in the outfit preview images are not part of this collection)
All the races included in this collection are the Clean versions. Check out the individual product pages for more preview images.
OBJ, FBX and DAE are provided, but for full functionality, please use the Blend files. Race files are fully rigged, outfits and hair styles have the vertex groups for rigging, so you just need to add them to the rigged character file and they'll work fine. I'd recommend setting this up in Blender and then exporting it for your specific game engine.
