[RELEASED] Terrain Stitcher

https://gyazo.com/403c0d73bc16a9c774047f7b588b1ce3
It works at this version. Did you check at clean project?

Not possible.​

 

Sorry, I just deleted my original post. It did actually stitch the seems of the terrain together. I mistakenly thought it would also combine all terrains into a single terrain. Apologies!!

 

Adding the "TerrainNeighbours" script to the scene will get this error, as a result the Terrain LODs problem still exist. Do you know of a fix? Thanks!

You coppied terrain and few terrains have the same terrain data.

 

I fixed it before I saw your reply, & hope it doesn't come back.

The terrains were indeed copied many times during their creation by a well known terrain composing addon, that tool bugged so much & regenerated the height of my entire game randomly once in a while, so I deleted the entire plugin & decide to use your Stitching Tool with the default Unity brush, works great. Stability is above all else.

I fixed it by renaming the terrain folder & some pieces.

 

I stiched two terrains together but when I save my project the seam reopens and I get a small vertical wall. I added terrain neighbours script to both terrains.

 

It's LOD difference. You need terrain neighbour script to keep lod verts at same position

 

I'm working in Unity 2019.1.1f1 and used neighboring terrains. I first created the terrains and then imported raw files as the heightmaps for each terrain it looked great until I started running around the terrain and finding some seams. It isn't visible across the whole seam, just parts of it. I attached an image of one of these areas. Is this something that Terrain Stitcher would be able to fix? Thank you for any assistance you may be able to provide.

 

All terrains have same ID?

 

Yes, they all have a Grouping ID of 0.

 

Hey Nature Manufacture! Long time fan of your assets! I never got this one as I am searching for a way to combine terrains of different sizes. It appears to be impossible even in mid 2019. Nobody seams to have any helpful info, I'm wondering if your asset may have changed by now or you know of anything that might work.

I want to take existing Unity terrains and combine them while keeping all vegetation details. I don't want to export hieghtmaps and re place anything. I also have this fantasy where one could work on a small isolated terrain (say 200x200) and get the details just right, and use something like your multiple terrain brush to essentially merge this tiny location into a barren part of a larger map.

I hope this makes sense. I don't think it's possible but thought you might have some insight. Thanks!

 

Stitched the gaps no problem thanks.

However I then found the issue in the image below.
I am not sure what is causing it but only noticed it after stitching the terrains.

I use Vegetation Studio Pro
CTS Terrain Shader

Have regenerated splatmaps and normals etc but cant seem to find a solution.

I will post in CTS and VSPro forums just to make sure.

 

How unity 2018.3+ you simply paint same texture at the borders.

 

Hi NatureManufacture.

I have 4 terrains that are randomly spawning and come forward when you press play. i want to hear if there is a way to stitch them together as they load.

Sincerely, Nicolai

 

Greetings, I was hoping to seek assistance regarding the Terrain Stitcher tool: I attempted stitching Terrains, however couldn't determine whether any changes did in fact occur when I selected the: "Stitch Selected Terrains" button... It appears nothing has happened at all... Each terrain is saved as a prefab, would that matter? I also included the _TerrainNeighborsManager in the Scene, but to no avail... The terrains are duplicates, possibly that is the reason why too? I'm on v.2019.4... Could you or anyone here offer advice, Thanks so much, and Sincerely, Ev.

 

Same here. Not working with latest 2019.4.4

I'm trying with just 2 simple terrains, i select both and click the stitch button. It should be that simple right ?

 

Is there an option to merge multiple terrains into one object?

 

nope.

 

Hi NatureMaufacture,

Is it possible to instantiate and stitch terrains at runtime?

As an example. I go with my player near the edge of the terrain. A new terrain will be instantiated and automatically stiched to the existing one so i can walk to a new terrain.

Thanks.

 

Hi
It's only editor tool.

 

Greetings, I jutst gut the stitcher and so far I am pretty happy with it, as it looks like t it will be able to save me some time.

However, I wonder if I am doing something wrong, because if you look at my screenshot, you will notice that there is some minimal spacing between the terrains. Is there a way to get rid of such spacing between the borders.

I am using Trend with a Trend Length of 100 to stitch.

I added the _TerrainNeighboursManager to an empty object as you mentioned to do this a few times but it still happens.

 

Terrains have same ID group?

 

Having issues. It say my terrains are smaller than stitch range. How can I resolve this?

 

its verts range not unity distance. Im not sure what is the smallest value but there shouldn't be problem. You have terrains 32x32? Could you share screen?

 

you have 32x32 verts on the whole terrain. They are copied. Did you add them coppied heightmaps or separated heightmaps? Each terrain should have its own terrain data file.

 

It works when I move the average length to 1. I just lucked into it. Thanks for the support.
