We've been progressing and iterating on Terrain, improving on the stability and user experience.. Our ultimate goal is to create something to allow large open worlds easily and procedurally.
We've recently added:
• Box3D physics (faster, more stable)
• Terrain Material physics (sand or grass would have different footsteps, bounciness, etc.)
• Importing heightmaps and splatmaps
• PBR materials with auto packing
• Cloud Terrain Materials
• Custom shader API and a material override
• Documentation!
Height blending materials creates much more realistic blends between materials.
Holes for caves.
The most obvious thing that's missing right now is foliage, grass & trees. We're working on that now.
