3. Mixamo - https://www.mixamo.com
Note:
The point is to create a character for your model, the same skeleton as on the models in the asset, the same number of bones and the same names. Otherwise the animations will not work. We create the skeleton using the Mixamo website, it automatically generates a skeleton for your model. But before loading your model into Mixamo, make sure that your model does not have a skeleton, but only a mesh. It is also desirable that the body model is not divided into components, such as legs, arms, head separately...
After you have created your skeleton in Mixamo, you need to open the model in 3d max. And use the Auto Bip script to create the bones and rename them. It will create bones called Bip 001, you will need to remove one 0 from each bone of the skeleton to make Bip 01. After this your skeleton is ready. We export the model from 3d max in FBX format. All is ready!
By the way, you can use all character models and animations from the Mixamo website in your games. The license is free, they allow you to use their models in your commercial games!
