If you have any experience in 3D modeling, I feel it's quite closer to 3D Unwrapping than software development.

You got a bitmap atlas ("context") where you have to cram as much information as possible without losing detail, and then you need to massage both your texture and the structure of your model so that your engine doesn't go mental when trying to map your informations from a 2D to a 3D space.

Likewise, both operations are rarely blemish-free and your ability resides in being able to contain the intrinsic stochastic nature of the tool.
