since this process for RWT is heavy and I sometimes experience crashes I would like to know if is possible to disable the tiles after they are created and unload them from the scene.

I'm open to any suggestion to deal with it

I create a vanilla 3D URP project with:
Unity 2022.3.24f1 LTS
+ Real World Terrain 4.9.2
+ Gaia Pro 2023 - Terrain Scene Generator v4.0.5

and I have an error message in Real World Terrain when try to use Gaia Stamps as output. See attached.

I can't figure out the cause. Any idea?

Thanks,

At the moment (in 2018) I am using your RWT asset and an asset that works well with yours called RTP (Relief Terrain).

It's a tool that allows me to switch, when I get close to the terrain with the camera, from the real google/bing texture to a 4/8 layer shader and transform the terrain into sand, grass, rock etc.
Unfortunately this RTP doesn't work in URP and I need to use this render pipeline.

I was wondering if you knew any system to achieve a similar result?

RTP works by saving the Steepness and Height maps of the terrain tiles generated with RWT and, through a Combined Heightmaps texture, allows you to automatic paint the various layers (sand, grass,..) on the terrain in a perfectly correct way, by modifying other parameters too.
(You can see RTP interface attached)

I was wondering, could this result also be achieved using terrain tile splatmaps?
And could you create a tool that extrapolates these splatmaps from the generated RWT terrain?

Thanks a lot for your time

I am working on a project which creates digital twin of certain location. Application will able to create an area with online or offline data. the app doesn't need to stream the terrains, terrain should be static and highest quality.

I am planning to use your assets for this project but couldn't decide which one suits more for my needs.

I can summarize the requirements as follows;

- should work runtime on windows build (online and offline)
- should be able to use local or online data (local data without custom server)
- should create huge areas like 100 km2
- should be able to save created terrains
- shoud be able to create buildings with osm and shape files

When I reviewed your applications, I made the following observations;

Real World Terrain:
- Working editor only
- Working with online data sources as tiles
- Creating terrain with offline data only works with custom servers and If I have a big satellite imagery I have to tile myself (correct me if I am wrong)
- Can create huge areas

Online Maps v3
- Working runtime
- Canvas size limited, I can't create 100 km2 area (corret me if I am wrong)
- Unable to maintain real world scale. Scale changes according to canvas size and zoom amount
- Can't use SRTM elevation data (Free bing tiers running out too fast)
- Can't freeze generated terrain and use it offline

These are my observation and assumptions. Whichever asset meets the needs I said more, I can start with it and develop the rest.

I'm again asking for your help for an improvement ... or rather, for something that exists but is not working properly.
I am sending you the geographical position of the area that interests me and also the screen of some parameters.

With your help these days, I have solved many problems. Thanks for your help.

But I have another question. Why is there some difference between the terrain altitude I downloaded and the actual altitude.

The actual height of the area I downloaded is 1380, while the downloaded height is around 1120. How can I download the true

terrain height?

The attachment is a screenshot of my download settings.

I have encountered another problem.
I first downloaded a large range of terrain using RWT, and then downloaded a small high-precision terrain.
However, the anchor point of the former is in the lower left corner, but the latter is in the center.
This caused me some trouble with coordinate conversion.
How does this need to be set? Why is there such a difference between the two?

In addition, does our plug-in have its own coordinate conversion method about conversion of unity coordinates and true longitude and latitude coordinates?
I added a target on onlineMaps, and then transferred the corresponding position of longitude and latitude in the three-dimensional terrain to generate the target. But I found a significant positional difference between the two. I use my own method to convert, and I feel there is a certain error. I downloaded Google's satellite maps, while I used Mapbox for RWT.
I don't know if my conversion method is not very accurate or if the two map sources are different.  Can I directly apply the downloaded offline satellite images from onlinemaps to the RWT Terrain? HAHA~ Can you give me some suggestions? Be deeply grateful!

By the way, these two plug-ins work well together. They help me a lot, you too.

Is there ah way can use whole world earth
Noz need be round

With worldstreamer or world streamer 2

You add also world stream 2 support or better use it manually

Like this for example but with RWT
https://github.com/SimBlocks/OneWorldSDKforUnity

And is there a way that create whole earth with RWT and wolrd stream 2 but that can add more countries or continents then because whole earth with RWT in 1 screne will be do big. Before create multiple scenes with World Streamer 2.

Or can combine   this https://github.com/SimBlocks/OneWorldSDKforUnity with RWT for Buildings River and more.

Both will be good find a good solution for flight simulator game with whole world earth.  But with RWT and WS2 near if get out of plane have also good looking game.

I tried to download terrains by RWT.

However, when RWT generating textures, an error would pop up when the progress reached 85%.

I had tried three times and adjusted the download level, but the result was the same.

Please see the attachment for errors. And I wish you can give some advice. Thanks!

As you may know (I already made several posts about this question) I would like to have a better resolution for my RWT which don’t seem very realistic with a 30 or 90m resolution.

With Qgis, some plugins and Blender, I can create an obj with a 5M resolution using IGN 5m rasters.

As my project uses many of the RWT actions, my concern is now to replace the RWT by this new mesh, and I am wondering if I could do this with your Mesh to Terrain asset ?

I don’t see anything about a possible bridge between these assets in their documentation?

If this is not possible, I can make a workaround placing the RWT terrains without the textures under my new 5m resolution terrain.

Or anything else that would be better?

Best regards.

We purchased RWT primarily for its scripting capability. Our use cases demand that we eliminate the possibility of human error. We ultimately seek to build a unified (stichable) collection of Unity terrains composed of SRTM 1-arcsec cells. RWT’s API documentation is class/type-oriented but does not offer scripting “How-Tos” as far as I can tell. Can you point us at scripting tutorial content relevant to our goals or provide a walkthrough of how one might use RWT’s APIs to accomplish the equivalent of the required GUI-based workflow?

Thanks!
