Two to three minute 3d animation short trailer

Hi, The base character has been built. Most animation of the character will be looked after by our own 3d artist (including character rigging). What we need from you is to create the required environment for the character to perform his animations (character animation will be taken care of by us) and with his actions, the environment should respond. Our artist will do the animation in Iclone and you can take the animation of the character to unreal engine or your preferred application and do the rest of the environment animation. For example, the character will move and open a curtain, so this part of this character will be done by us, but you will need to create that curtain and also animate it so that when the character initiates his animation the curtain also moves .
