Terrain effect in unity iphone

Hi All,

How to do terrain effect in unity iphone.

Thanks

What do you mean with terrain effect?

If you mean the terrain object: you don’t, its not supported. “Terrains” on the iphone are done through meshes

how about newer machines ? iphone 4 or ipad, don’t they have enough power to run the terrain engine?

I guess it would make backward compatibility a problem though

No even those are not able to.
Unity 3 does not support terrains on the mobile platforms (given you own the corresponding addon)

especially the iphone 4 and ipad are too weak cause they have the same gpu as the 3GS, just much more screenspace to render

Although people are finding that the iPhone 4 renders significantly faster than the iPad, even though it’s somewhat close in number of pixels. I haven’t seen any explanations as to why this should be, but when you have 30ms render time on iPad vs. 5ms render time on iPhone 4 for the same scene, something is going on.

definitely.

though that might have to do with the scaling value and potentially scaled up normal iphone resolution with AA enabled for example.

Cause otherwise there aren’t much reasons for it especially as the iphone 4 has a clocked down cpu compared to the ipad.

No, it’s specifically 960x640.

There’s clearly some difference, somewhere, somehow. Maybe drivers, maybe the hardware isn’t actually what people think, maybe something in Unity, etc.

Even though it’s not available in Unity iPhone, I believe the option to export it from Unity should be available, and would be extremely useful for those of us not using standard Unity. You obviously wouldn’t/couldn’t use hi rez mesh data in Unity iPhone, however with poly reduction in an exporter for Terrain (and using some iPhone ready assets), it could help to shorten production time and bring the use of the tool sets together.

I’m sure there are the few that wouldn’t agree, but I’ve listed comments on it here. Check out my forum posting link attached.
