You can also run the updater with the latest version 2.32.
Version 2.32 evolved into a pretty big update. The biggest improvement is the internal entity storage system. An octree is used to store all top-level entities, and the rendering and picking routines are now recursive. The view range setting is now an integer category, instead of an arbitrary number. This allows the engine to dismiss chunks of scenery if they are far enough away from the camera, without having to iterate through each entity.
Vegetation rendering was rewritten and optimized. The disappearing vegetation shadow bug was eliminated, and vegetation collision added. You can set the collision type for the layer in the vegetation properties panel in the editor.
Collision trees will build much faster now when meshes are loaded. You can also use the supplied gmfprocess tool to create collapsed GMF files with pre-serialized surface data for raycasting. This will make meshes load faster.
2.32
-"Render" Lua object function renamed to "Draw".
-Added Draw entity callback.
-Entity draw callback and Lua "Draw" object function will only be called at most once per frame. Perform animation in this function.
-Entity LOD distance parameters changed for better performance.
-LoadAnimation now works without exact hierarchy matches, so LOD meshes can all use the full-res animation.
-Implemented entity octree with hierarchical culling and picking.
-Rewrote vegetation rendering routine.
-Added vegetation collision.
-Added optional terrain color map.
-Fixed some problems that prevented custom buffers from working.
