Export The terrain to a 3D app ?

anon_44343528 · February 28, 2009, 3:27pm

Hello,

It is possible to export the terrain only (obj or others formats) to a 3D app like silo or VUE, to tweak it ?

Thanks a lot.

export: perhaps
but you could never again import it.

if you want to work on the terrain aspects outside, you have to use the outside app to create heightmaps that you import into unity.

Terrain .obj exporter.

Thanks !!

No problem to re-import inside unity after ?

(I wait for the 2.5 and don’t have any versions for the moment).

In fact i will test to export the terrain in a 3D application and test boolean operations to dig caves and underground rooms inside.

I know that has been talk, but have you test in this way ?

And if it’s don’t work, i think i can tweak my surafece terrain to create natural deformations.

thanks a lot !!!

You can save it from your 3D app and import it as an ordinary object. However, it will no longer be a “terrain” as such, and won’t be able to use the terrain functions such as the shaders, trees, LOD, etc.

Just a note that I changed the terrain .obj exporter script mentioned above so it’s a proper editor script now, with a little window for choosing the options and a file dialog. Nicer and less clunky. Requires 2.5 now though.

Just a side note about Terrain Editor functionality here. Is there any way we can use the terrain editor’s texture and object placement functionality on normal objects? So we could have grass on terrains from 3D apps, without having to script it so it faces the camera, and custom script wind? THAT would be awesome!

Oh, and thanks for the Terrain OBJ Exporter! Now I can make my paths better, and do caves and the like.

The terrain features in Unity are specifically tailored to run on a heightmap and can’t work with anything else. Glad you like the obj exporter though.

Awe… Shucks.

Well, that mean making custom wind scripts (maybe not), or at least custom billboards.

The wind is a shader…I think you could use that on normal objects that are set up correctly (could be wrong but I think it uses vertex colors?). Obviously I haven’t looked into that.
