Reference:

The aim of the project was to create and animate CG objects in the photographed background. The key component was to have an accurate light integration through the use of light and compositing techniques.

 For the duck, I had a toy mouse as texture and lighting reference. I tried to take its texture and lighting information when creating my CG objects- wooden duck toys. I tried to achieve the toy's 30% reflectivity and cracked and painted wooden surface to the duck I modeled in Maya. 

 

Textures:

The main aspect of the project focused more on lighting and compositing, so I spent less time on texturing the objects. However, I looked at photo references and tried to exaggerate some parts such as cracks of the wooden duck. In the original toy mouse that I had, the cracks were very thin and almost not visible unless you look very closely. I made the texture for my wooden toy to have more visible cracks to emphasize that they are have been used. Same detail applies to the wheel that has white parts around the edges.

Environment shadow over the object:

While the wooden duck focused on having environment and ambient reflection, the challenge of rolling soccer balls was the fact that it has an environment shadow go over the objects as they were rolling. The shadow on the ground was based on the photograph of the background with the light blocked by the black cardboard. The shadow of the bar was based on the render view that was taken from the position of the main sun light. The image of the render view was brought to Photoshop, and I adjusted the levels and contrast to make the image as shown below.

Reflections on the wooden duck:

Both environment and ambient reflections were used. The photo of the background with a chrome sphere was taken in the beginning, and the image was cropped in Photoshop so that it can be plugged in to form the dome in Maya. The problem that I had with ambient reflection was that it was very green which when composited, did not look right on the yellow surface of the duck. I had to use HueCorrect node in Nuke to fix the color.
