Hey Developers,

Today, we’re excited to announce the launch of Roblox’s brand-new pathfinding system, which is now available to all users. This brings awesome new features along with huge improvements that will allow developers to create more accurate paths and produce innovative gameplay experiences.

Here’s a brief summary of the improvements made to the pathfinding system.

Improved resolution: The old system used 4x4x4 voxels. The new navigation mesh system is built on a 1x1x1 voxel grid. That’s 16 times more detail!

Dynamic Navigation Mesh generation: The navmesh will automatically regenerate when obstacles move around the world.

Background tile processing: All navigation mesh tiles are processed in the background, without blocking any of the main engine systems. This means scripts keep running, and it’s less likely to drop frames.

All obstacles are important: In the old system, small obstacles or thin walls were ignored by default. In the new system, all obstacles are marked as such and rendered to the navmesh.

Avoid non-traversable areas: The new system takes into account the default size of the humanoid and avoids areas where the agent does not fit.

Automatic Jumps: The new system automatically detects which areas could be better connected if the humanoid jumped.

With that being said, we encourage our developers to make the best use of our brand new pathfinding system to create new unique experiences for everyone in our community! If you’re a member of the Developer Forum and you’ve experimented with this new system and have created anything impressive with this, we’d love for you to share it with us on the Developer Forum or by using #RobloxDev on Twitter!

Below we’ve released a few wiki articles to help you get started! We will be releasing more articles in the near future and will keep this thread up to date as new information is available for our developer community to check out!

The new pathfinding system is live on PC and Mac, and will be coming soon to mobile and Xbox. We will update this thread when it becomes available for the remaining platforms.
