image composition/passes

[neyes_ice]

 

Good afternoon guys. I would like to ask your help regarding my images. 1st image is the base. The 2nd image is the one i would like to achieve, to be able to compose them like the 3rd image. I know how to use the render mask script for individual objects but i don't know how to retain the shadows and reflection like the 2nd image. I am using this style of rendering because if my clients want to ad or remove something from the scene, it would be easy enough so that i wouldn't have to render the whole scene. btw I am using 3d max 2012 and vray 2.0 for my images. thank you and i hope i am in the right thread.

Matte shadow should have work by the way.

Definitely use matte shadow material. Follow this

Apply the matte shadow material to the floor and render. This way you get your chairs + the shadows. Only problem is- I don't think matte shadow material will preserve the reflections. Someone correct me if I am wrong.

Good luck.
