Description
A scene built from modular pipe pieces I made for a mobile game. The pipes share one 512x512 diffuse map with an alpha channel used to control the amount of color each pixel receives from vertex color. The diffuse map itself is mostly grayscale with the exception of some brownish dirt.

This way pipes of every color could be drawn in a total of one batch and with small memory footprint. In practice, however, shadows add a few batches.

Modeled in Blender, textures hand-painted in Photoshop, rendered realtime in Unity.
