L3DT and Unity - Create and import Maps ???

Scene & World Building Terrain
1

Hello,

I just created a new test terrain that is 4096x4096, 8x8 tiles and 41kmx41km.

I saved all the maps in L3DT but when i try to import it (Raw file) i’m not able to do it correctly.

What are the steps to import raw files, i want my super map be splitted into lots of terrains, (for this map is 512x512m tile).

So what i need to do ?

Please some help will be greatly appreciated.

Thanks a lot.
Best Regards.

Oh, thanks a lot !! :wink:

But i’m trying to import my big terrain splitted into more little ones in a single import, after i will use stich script or if not necessary, and use antares to pre load my terrains.

It is possible to import all my terrains block into one import ?

Thanks a lot !

Best Regards.

I also purchased starscenesoftware.com - starscenesoftware Resources and Information.

L3DT does make some pretty large terrain. I have a pretty large island mass set that I get lost running around on.

I have Stitch script, but i was thinking that for L3DT, as the splitted parts option is inside the software, that stitch will not be necessary.

I opened a topic on the BundySoft forum, and an Admin ask me :

" What type of Raw file Unity require ? "

Is Somebody knows ? For my part i don’t know.

Could you say me more on your big size island ? Size, number of terrains ? And how do you import it in Unity please ?

Thanks a lot !

Best Regards.

I think you will need stitching. I did what you are trying to do. It is fairly straightforward. I just set the tile size in L3DT to 1025 and exported away. They work fine on their own, but, counterintuitively, the edges did not line up perfectly. I suspect is has to do with the requirement that HMs imported into unity have to be a power of 2+1 (why is that, by the way?) At anyrate, I used Eric’s stitcher, and things looked 99% perfect. You’ll see what the other 1% looks like when you do it.

The problem is for the moment , when i import raw file of my big terrain, it import one big terrain, and NOT one big terrain sliced into muliple parts (small terrain parts).

I have just one terrain, so i don’t know how to import this file correctly, and work with it after.

So, you think i need to stich every terrains ?

I need to stitch 64 terrains together one by one ?

Thanks a lot for your tips.

Best Regards.

If I understand what you are trying to do, you want to take your large terrain heightmap from L3DT and import it into Unity as that heightmap split up into smaller tiles, right? When you export heightmaps from L3DT, there is an option to export it in tiles. Use it. Just figure out what size you want your terrain tiles in Unity to be, and export it in tiles of that size + 1 (if you want 512x512 terrain tiles in Unity, you have to have it export heightmap tiles as 513). If you have 64 heightmap tiles, then you have to add 64 terrains to your scene, and import a heightmap tile for each one. Then, you would do the stitching.
