Zombies Pack V1 v2.1 (Latest version)
UPDATE: Version 2.0: Added models cut to Body Parts. Added Open Mouth Blendshapes
UPDATE: Version 1.5: Added one more skin for every model. Better materials, and better geometry.
This Zombies Pack consist of our five zombie models, each with two sets of skins.
Three males and two females.
Each model has two variants, one with whole body/head mesh and a variant with detachable body parts, to be used with Dismemberment systems of your choice, or to just hide/show them
I recommend Dismembering by Hartvigs IT which was made especially for my models.
Heads of each of them have an Open Mouth blendshape for easier bite animation.
All models are textured and skinned, Mecanim ready.
Models have NO ANIMATIONS, you must use Mecanim compatible animations to live them up.
2048pxs Albedo, Normal, Metallic/Smoothness maps.
All models have skinned Eyes and Jaws.
The Pack is compatible with most Mocap packs in Asset Store, you can see a test using ZOMBIE Starter: MoCap Animation Pack by Motion Capture Online in the video bellow. They have Pro and Basic packs also, check them out!
