The caterpillar I started with low poly and then worked with ZBrush for the modelling (Fig.08). I used the Standard brush for fine structures with Alphas; here are some of them (Fig.09).

Texturing was done with ZBrush and Photoshop (Fig.10).

For rendering I used the V-Ray renderer with GI on, Irradiance map set to High for the final render and Light Cache Subdivisions at 500. The Environment was on with a multiplier of 0.6. Here is the final render with and without materials (Fig.11); V-Ray Lights with subdivision 32 (Fig.12).

The final picture was rendered with a resolution of 6000 pixels. The challenge was to generate depth from a frontal, symmetrical composition. I used Render Elements to render a VRay ZDepth picture (Fig.13). With After Effects and a Frischluft Lenscare plugin, I rendered the ZDepth information in my final picture.

Post-production was very simple; only 2 extra layers with some colour variations were used (Fig.14).
