This was a collaboration I did around 5 years ago with ParkerBiley (http://www.parkerbiley.com). It was great working with Clive Biley on the CG creatures, and putting them into John Parkers photography.
I modelled the centipede from scratch in modo, then into Mudbox for sculpting and back into Modo for me to shade and light to then render. Fair bit of detail in the model to catch nice highlights.
The spider was modelled by Clive, who then handed it to me for shading lighting and additional texture layering, to get it to sit in the shot.
Maya was used to rig the centipede to get it into pose.
