Making of Breeding Chamber by Raul Fabian, Romania



Concept

Breeding Chamber was made for Ruins contest on CGArena, but I didn’t wanted a classic image with ruins, so I decided to add to the ruins some alien strange looking stuff. After dozens of ideas I finally found something, the eggs were perfect(everybody knows the alien movies). I wanted a more special look, something not easy to find on earth. The  final decision was to see the ruins from inside, to see the effects of the time .First step, I draw a sketch on paper, after that I scanned it and quickly prepared it in Photoshop cause I was short on time. That’s why I have used not very complex models. This is what came out:

Not very accurate, but enough I think for a first impression

Modeling

The walls are created from 20-30 pieces. We just need to create one, and multiply it using array tool .For the first piece I started from a classical box (Standard Primitives), using polymodeling. Everything is made using extrude and bevel functions, after that just moving some vertices and voila, one half of the wall piece ready.


So now we have a half piece. We just have to delete the red marked polygons, mirror the half. The 2 halves need to be the same object. After that we just have to weld the corresponding vertices, that vertices which are one in front of the other. This is the final piece:


Now we just need to use array tool with the correct width on the corresponding axis and we have 30 pieces instead of one.



The floor is just a simple box, and the pipes on the sides just standard cylinders nothing more. For the floor gridlines I made some more standard boxes, arranged in a form I liked best. After that I have used Boolean tool with substraction. It has substracted the gridline boxes from the floor.. I also broke some parts of the floor to make a more ancient and old look. The wall in the front is nothing more then a standard plane .As I said, everything is simple modeling.



Now the next things to model were the eggs. Again very simple, a standard sphere modified using poly modeling. Some more extrusions, beveled polygons and moved vertices and the egg is ready. I have added a noise modifier to obtain different egg shapes. Finally I have cloned the egg, and changed a little bit the noise parameters. The wires hanging around are created with shapes. Both the wire things at the eggs base and the bigger wires were created using loft function. For the loft I created a circle shape and a line shape with smooth edges. You can see the result. For a better look I have broken some more pieces there and added to the wall pieces a smooth modifier.



We have finished modeling now, as you can see very simple models.

I made also an occlusion pass, for a better quality of the darker areas. It was rendered in VRay with no lights just Global Illumination, a white background and white VRay materials applied to all objects.

More details on Occlusion Pass can be found here: http://zivcg.com/occtutorial.html

For a better effect you can make the occlusion pass with white materials applied to all the objects, but using the bump map of each texture. See following image:
