Hey all!

Today I will share a new addition that we’ve been working on: spline-based paths. It’s something I’ve been wanting to implement for a while to give more control and realism to the landscapes in the game.

State of PCG Spline Path Generation

One of the big challenges many devs face with procedurally generated environments is finding ways to create realistic, organic paths through the forests without losing that hand-crafted feel. Spline-based paths seem to be the answer. The cool thing about this approach is the ability to define smooth, curvy paths that can snake through the landscape, following natural slopes and avoiding obstacles like trees or rocks within a forest. These paths feel more intentional than a random scatter of roads and trails, giving the world a more lived-in look. It’s really coming together, and seeing a smooth winding trail cut through a dense forest is super satisfying!

What’s Next?

We will continue to tweak this system and see how clean we can get it so it will work flawlessly within the Advanced PCG Forest. Let us know your thoughts and if you’ve had any success or failures in creating roads in the past.

Next week, we will look at a follow up to our ongoing progress of forest features and explore PCG Ditch Generation and Land Deformation!

With kind regards,
