Optimising Terrain Drawcalls

Unity Engine
1

Hi,

I have a simple terrain I wanted to use on a mobile app, but it has around 300-700 draw calls for the terrain alone. To optimise I thought about exporting the terrain to blender and optimising to a single mesh with 1 texture atlas, but the main issue is what to do about the terrain collider?

I’m thinking of loading my mesh, then creating the collider at runtime setting the terraindata in script, has anybody done anything similar to this that may have a better solution?

Thanks,

Jon

You can’t create a single mesh, it will be far too big (unless your terrain is very small/low-res). Try increasing the pixel error in the terrain settings.
