Three series, each numbered and open-ended. Everything here is written against a specific engine version, includes the profiler numbers, and says what did not work — which is the part almost nobody writes down.

Shipping Kits

How a commercial environment kit actually gets made.

Everything between "nice render" and "a studio bought this and shipped it". Spec, grid discipline, trim sheet planning, naming conventions, LODs, documentation, and Epic's technical review.

A modular cabin kit laid out on a grid against a plain background, with module dimensions annotatedShipping Kits/01Spec before modellingEvery modular kit I have shipped that went badly went badly for the same reason: I opened Blender before I knew what the modules were. Here is the one-page document I now write first, and the four decisions it forces.
Grown, Not Placed

Vegetation, biomes and foliage that survives a frame budget.

SpeedTree, Nanite foliage, wind, scatter and biome transitions — with profiler numbers, not vibes.

Killing visible texture repetition.

Macro variation, cell bombing, distance blending and the Substance Designer authoring that makes breakup cheap. Unreal and Unity where it makes sense.

Once you can name what your eye is catching, the cheapest fix is four nodes and about ten minutes.
