3D Plant modeling and short animation

Hello,

We need a short animation for a biogas plant. I will be maximum 2-3 minutes. 3d model is ready (3dsmax) but we want to improve it and get much better renders with animations.

Animations:
- Workers in the site will walk around
- Cars will move
- Mixer will work ext.
- And some fluid animastion for pools and pipes

I will explain with some examples.

I am uploading an example for a 3d biogas plant.
