Hi all. Here is a little tutorial based on the render you see above. I shall discuss the material setup (using the maxwell v1.1 c4d plugin) and then the lightiing.
Step 1 :
First prepare your scene by making sure everything is modelled to real scale, ie. if its 10mm in the real world its 10mm in cinema 4d. I placed the model of the fire truck in a large chamfered cube and then I cut top off, I then reversed the normals. (image 1)
