Plenty of people on death row recognize they fucked up . No ones gives a fuck about that . Bring on the resignation , bring on the consequences . <| sep |> It depends on how you ' ve created your model and how you import it . Usually , people use . 3 ds , . obj and . fbx as import formats mainly the last one since it ' s more complete , so you are limited to these format ' s limitations . Not all blender resources are compatible . I use 3 ds max , so won ' t be able to be more specific , but things like clothe and fur simulators usually are not supported . You need to make sure unity ' s and blender ' s scale system is the same , and also axis orientation . I don ' t know about blender ' s , but 3 ds Max ' s materials are not supported , so I import the model and the texture separately and compose it inside unity . If you want any king of unusual effect on the material , you need to program or download a shader to do it . If your model is uv mapped , you need to make sure all the parts are inside the first tile or it won ' t work properly . I don ' t know about animation import on blender , but in 3 ds max it ' s made using a fbx file . These are very common limitations and almost every game engine will have similar ones .
