Hi, When I launch the game on android device, the terrain gets all blurry and very low quality. (both textures and geometry of mountains etc…) What is causing it? Also what should be optimal terrain resolution when working with mobile platform? The terrain Iam working with is 3x2k resolution…
To fix geometry of mountains try this:
Open terrain in inspector->go to last tab(gear icon)->increase Pixel Error. Be warned though: higher pixel error might take a toll on performance.
To fix blurry textures on terrain try this:
Open terrain in inspector->go to last tab(gear icon)->set a material. Material should have Nature->Terrain shader.
As for your last question, it heavily depends. There is a lot of other things to take into consideration: pixel error, amount of textures attached to terrain, resolution of those textures. Best advice anyone can give you here is to make a test scene with approximately the number of assets you’ll have and then play with the mentioned settings and terrain resolution and see if it works fine or not.
If you are using Tegra, oh man welcome to the Tegra bugs :).
A workaround you can do is split the terrain in pieces.
