Hello, I wanted to show you the technology we created for our game "Edge Of Eternity" it's still a huge WIP but we plan to sell it in a few weeks on the asset store but before we'd like to known if you people are interested in this system. The mobile terrain system work by converting the existing Unity Terrain into procedural geometry, we transfer every datas from the original terrain, texturing, planting, geometry, etc ... so you don't have to work on multiple terrains or use badly optimized tools, the recalculation take about one second when clicking the rebuild MTS button. The system allow you to have a terrain on mobile that have a lot less drawcalls, lot less triangles and batch everything ! The mobile terrain system create procedural geometry tiles and use the unity LOD system to swap them depending on the distance. MTS allow you more control of the terrain quality like distance based LOD quality, shadow tile distance, directional lightmapping for bump/spec and much more. The mobile terrain system have been tested within our game that run really smooth on 2011+ devices (Galaxy S2/iPhone 4S) at least for bumpspec, diffuse setting can allow you to reach less powerful devices but we didn't tested it on real game situation to check the performance. The mobile terrain system fix some major issues that Unity Terrain have on mobile like the "pixelating" bug of textures on low precision mobile gpu like tegra 3 or mali 400. By using LOD system it allow much more near details than using a geometry for mobile terrain ! What the mobile terrain system can do for you ? (Open images in new tab to view the triangles / drawcalls) Every screenshots have far clip distance 1000 High control level of detail (control near and far LOD quality) Low mobile quality High mobile quality Comparison with Unity Terrain at the same settings (pixel error 1 for Unity Terrain and LOD Quality max and Geometry Level max for MTS) Unity Terrain MTS Terrain High We still have to work the normal calculation to have the same shadowing than the default unity terrain it's still an early prototype ! We managed to optimize shaders per platform and make bumpmapping / bumped specular on mobile to run smoothly with directional lightmaps ! We'd like to hear any feedbacks !
