Normally our devlog posts at the beginning of the month are reserved for general development progress and gameplay systems, but Spencer and I wear many hats here at Random Seed Games and I've actually been working on some art related stuff over the last few weeks in preparation for our first survival sandbox map design.

We want to make the survival mode a unique experience from the story mode that will come later. So that means a unique map on release, and hopefully multiple unique maps over time. I decided that this would be a perfect time to revisit one of the most criticised aspects of our terrain... the rocks and cliffs.

The NASA data that we use for our terrain generation is incredibly helpful for creating basic formations, but there are some definite limitations. The data resolution and the inability to create overhanging rock formations combine to make the terrain look like a continuous flowing surface without many rugged features. To combat this we need to create rock meshes that protrude from the surface and form more realistic cliffs, etc. In the past we have relied on the Unity Asset Store as much as possible for rock models, but for cliffs we had difficulty finding appropriate models. So I spent some time this month creating my own cliff models using real Mars cliff photos as reference.
