Dev Diary 5 talks about smaller features we've recently implemented in Substructure: belt converters and variable recipes.
These add more variety to how machines and recipes work, and what setups players will need to build. #gamedev #indiedev

When texturing cliffs in Substructure, we wanted to avoid visible tiling.
So we opted for a sandstone look. Horizontal banding helps textures flow & inherent surface noise reduces visual repetition. #indiedev #gamedev

Most texturing in Substructure is done via Substance Designer & Painter.
To create cliffs, we produced a basic tiling texture & a heightmap to deform simple meshes into complex ones.
Here's the workflow. #indiedev #gamedev

To create cliffs in a 2D game like Substructure, we produce a 3D model & render out a set of sprites. Then stack the sprites in-engine, which lights them to create the illusion of 3D.
Here's a rundown of the process! #gamedev

This fully automated fuel farm was created by one of our playtesters for Substructure.
This player used underground belts to maximize the amount of land they can farm with each plot. #screenshotsaturday

For a game like Substructure, strong UI design is essential. This has been a big area of focus for our development team.
Here's a sneak peek of what the player inventory UI looks like.

Making an automation game involves some pretty complicated code under the hood.
Today's dev diary is about writing that code -- how Substructure handles data, how Lua definitions become C++ structures, and how reflection + annotations help things stay sane.

These are concept illustrations for the first two planetary layers of Substructure. They established the creative direction for everything that followed.
Bringing them to life was a unique technical challenge. Read more about it in our second dev diary!
