THE PROBLEM

This week I finally decided to change our main character model from the skeleton that we have to the real main character that you could see in the cutscenes. The reason why it took so long is because of how much trouble it is to change the models. If I just change the skinned mesh from the skeleton to the main character, it would rupture the mesh, or it would make a stick man out of it. Either way the model will not look like it suppose to. This is because of 3 reasons. First is Avatar that is unique to the models armature. Second is Mesh of the model that should be built for that armature and avatar, and third is armature itself. If one of those things is different then one of 2 things happen. First is the mesh becomes invisible. Second is the rupture and stretching of the mesh. If you are changing the models in the middle of work process when the player is completely finished and was fully build for the old model, then you have to make sure that the asset import parameters are the same. The exact same. Model, Rig, Animation, and Material parameters should be identical to whatever asset you were using previously. Otherwise, it will not work. There will either be a problem with normals, materials or amount of bones. 

THE SOLUTION

The solution that I found needs a lot of steps but is working. First you need to install a ProBuilder, then select the meshes that you want to have in collection. In my case it was main character, knight and magician models. Then you have to ProBuilderize those meshes together and export them as a group in an OBJ format. Then put it in the Mixamo. It will make the armature for the model. Then edit it in Blender to delete empty stuff that could be created by the ProBuilderize and save it. Then just download the models as FBX and you can use it in Unity. Before putting it in the scene make sure that the parameters are the same like I mentioned before. Then you can drag it in the scene and it will work.
