i am a student and i want to know how to create character in unity 3d and use it for animation.please help…
Unity is a game engine, not a modeling application. If you want to create a 3D model, you’ll need to use something like Blender, 3DSMax, or Maya to model, rig, skin, and potentially animate your character. You’ll then export your model from that application and import it into Unity, where you can make it render and animate in accordance with your game’s logic.
First, learn to use google.
Asking questions on forums is fine, but it is slow. It is best suited for specific, unique problems that you can’t find an answer to after several hours of searching and troubleshooting. At that point, you can’t do a whole lot besides wait for some solution to pop into your brain anyway, so waiting on some knowledgeable good samaritans to see if they can answer isn’t going to slow you down.
Everything you will need to learn for a quite a while is already all out there. You just have to search for it.
The basics are at blender guru (youtube) for free software, others for paid. Brackeys (youtube) also helps model and build a game with characters using blender.
