Hi there,

I cant seem to make height brushes work on my terrains.
I don't see the blue tool marker on terrain.
Works fine on your test scene.
Have also noticed that you mention it requires unity v 5.1.2.
I have v 5.1.1f1 and cant find v5.1.2.

Thanks

G

 

Hi

Your terrain collider thickness mustbe greater than 0. We use raycasts in our brushes. This should help.

 

I can now see it working.
My terrains are quite large so I had brush size to 50 but could not see anything happen.
I changed brush size to 12 and I can now see it closing the seams.
I cant see the blue marker though so it is difficult to guess where you working at but I can see that seam are closing up nicely.
Any idea why I cant see the blue marker?

 

Terrain size is not a problem. Do you have any errors? It shouldn't work like that. Could you give me screen shot from terrain collider? Contact me at skype: dahrrrr we will take a look. You said it work ok at test scene?

 

Apologies. it seems to work well on seams coming down the terrain but not across it.

Getting this error:

DivideByZeroException: Division by zero

In your scene it closes seams but can not see marker either.

G.

 

This error only shows when you got marker between terrains and there is no terrain that raycast can hit. You have got big holes than. If you want to stitch it, you only need to touch one border and it will work fine. We will fix that but basically this is not an issue. If you normaly moving brush on terrains it works fine?

 

No cant seem to close this hole.
Getting this error now...

Texture '' is degenerate (dimensions 0x0)
UnityEngine.Texture2D:GetPixels()
MultiTerrainEditor:OnSceneGUI(SceneView) (at Assets/MultiTerrainEditor/Scripts/Editor/MultiTerrainEditor.cs:772)
UnityEditor.DockArea:OnGUI()

 

Hole is not that large. Holes in your terrain are larger.

G.

 

Ok, I think you need Unity 5.1.2 or higher, some functions are not avaible at older unity versions..
http://unity3d.com/unity/qa/patch-releases here you can find all unity versions. I think Patch 5.1.3p2 is most stable at the moment. If this don't help you please contact me at skype. It will take few minutes and it should work fine.

 

Ok I now have V5.2.0f3

Have removed and re-installed Multiple Terrain Brush with same results...

Texture '' is degenerate (dimensions 0x0)
UnityEngine.Texture2D:GetPixels()
MultiTerrainEditor:OnSceneGUI(SceneView) (at Assets/MultiTerrainEditor/Scripts/Editor/MultiTerrainEditor.cs:772)

I don't have skype - will try to install and contact you.
G.

 

Ok, so I'm waiting I will also give this case to our coder.

 

I have sent you fix via mail. Please check it. It should help, if anyone else will have that problem please contact me. I will update pack at asset store.

 

Guys thanks for the help earlier today.
I used Terrain Stitcher and worked brilliantly.
Thanks again.

Hi~
Do your tool " Multiple Terrain Brush " can work with " Relief Terrain Pack "?

 

Yes I tested it few days ago. I think I will make tutorial. I would like to show how it works. Btw your terrains must be square size (XZ) until we will make update.

 

Anyone tried using this in conjunction with RTP? Might be interested.

Otherwise if you want someone to test it for the first time hit me up

 

As I said it work with RTP

 

Oops sorry didnt see!

 

HI ~
I press Alt+LMouse just want to rotate view for check,
I don`t want to paint terrain,
If i press Alt dont paint anything,Can you fix this?

THX

 

Sure we can add this option. Send us mail to naturemanufacture@gmail.com, We wil send you quick fix.

 

@NatureManufacture , wonderful little tool! I saw on the asset store reviews that someone else is seeing slowdowns with this, I only have it happening at times, not always, but its enough to be a little bit of an issue, is there anything you need from me to diagnose the problem? I saw you write as a reply to that review that it should be as fast as the default tools.
Running into a little problem when i sample height from the terrain, it often picks a completely different value than where I'm clicking. Always have to look at the editor window to see what value it decided to pick was too high/too low compared to the last value I picked. Any idea why the raycast isnt picking up correct values? ( using RTP on it, but i dont think that would cause an issue like reading wrong Y. ) Anyway, hope you have some idea of how to fix it.
Also, I'm wondering if a future collaboration with the author of the Erosion Brush would be possible? I'd die of happiness if i could run the erosion brush seamlessly between two tiles.. just a thought

 

It could happen when you are working at terrain borders. There are few things to upgrade, we are aware of that. We simply need to rewrite few things.
About your issue:
We use raycasting. Does terrain collider is from this terrain data? Ouh I forgot unity have a bug with near and far camera plane. That means if you use mouse scroll in your editor screen, near plane and far plane values are changing but center of the camera is still in the same place, so raycast could be from different place than editor camera truly is. That is why there is a difference between point you click and place the marker is. Please double click on any object at your scene - for example terrain. This will restart unity near and far plane camera values. This is unity bug, in some cases it could even cut models from your near view at editor camera. Try to double click on object and move your camera only by keyboard
We will fix that in next up, write me an email and I will send you fix earlier.
I had a waypoint system that uses mouse click (raycast ) to set up waypoint and I had the same problem.

About erosion tool we will try

 

Thanks @NatureManufacture .
About the erosion tool, i was just talking to the author, and he's actually been working on implementing a multi terrain feature to his brush, so no worries there between having you two potentially work together!
Yeah, it happens mostly at terrain seams, understandably. I saw you mentioned that there is smoothing happening as you're crossing over the seams, would it be possible to have a smoothing on/off switch in the window? I believe that it would speed it up, as I dont need that smoothing feature enabled at all times ( I mostly smooth stuff using the erosion brush , which obviously provides a much better natural erosion smoothing vs just brush smooth)
As for raycasting, yeah, i'm aware of that issue, it's the single worst thing that Unity never worked on for terrain manipulation, anything more than 4 terrains in scene and it's just much harder to navigate through ( doing a frame on cursor resets it by showing up the whole terrain instead of a more localized framing.)
By waypoint, did you mean something like the waypoint in the ramp brush ( if you're familiar with that brush?) where the brush would act along a particular path you pick? Man, that would be sweet in here, but yeah, i hear you, the terrain implementation is just bad in Unity ( not holding any hope with whatever they're rewriting for it in the 5.x cycle), so big thanks to you and the other asset devs that are improving the workflow. I'll shoot you an email to get access to the fix?

Update:
What would be nice since the raycasting/terrain issues in unity arent really working, would be to have a series of height presets that I could click on in the window to set it at a particular range? (y=100, y=200 ... , would be nice if those values could set set in editor itself, but I wouldnt find if it's a quick hardcoded thing to edit in the script itself?)
Thanks again!

Also for some reason I can't seem to get projector working in current project (not projecting texture on terrain), creating an empty project works, but the difference between 2 can't seem to spot.

 

I can't reproduce that at unity 5.2+, because I can't reproduce unity camera bug with near plane;/. What unity are you using?

Ok so there could be few things:
- Does your terrain have collider on? (we use raycasting), and thickness greater than 0?
- I will sent that to coder, we also could meet at skype and fix that ,but if it's work at empty project it could be a specyfic project setting. It will be great to know what could make multiterrain to stop working.
- Error could dissapear after unity restart. If you attach this pack sometimes you need to restart unity.
- Make sure that you have last version of our tool because we fixed alot 2 weeks ago.
- You need 5.1.4+ unity version.

Edit: I got fix for that. Sent me an email - naturemanufacture@gmail.com . Please include invoice number from asset store and I will give you fixed files.

Ah summary , this is why I really hate unity terrain, and unity editor camera.

 

This is really sweet asset. I left a message on your video if you care to check it out and also bump since more and more people need to realize multiple Terrains is the only proper way these days to work on your game and using an asset like this is very important.

 

Yeap this is the only sensible way to create world, but not in every game. Yeah I will answer it.

 

Hi - Just bought this - it works great on the sample scene. But I am getting some sort of conflict on my scene:
ArgumentException: An element with the same key already exists in the dictionary.
System.Collections.Generic.Dictionary`2[System.Int32[],UnityEngine.Terrain].Add (System.Int32[] key, UnityEngine.Terrain value) (at /Users/builduser/buildslave/mono-runtime-and-classlibs/build/mcs/class/corlib/System.Collections.Generic/Dictionary.cs:404)

How many terrains you have at the scene? We are fixing it right now. A dev with 121 terrains at the scene, had the same issue. When he work temporary on smaller count it works. Could you try this for a while?

 

Just 4 terrains at the moment.. I think it might be a naming thing. Just renamed a terrain which had same name as another and it did not error

 

Just want to say the tool works perfectly. I made 9 Terrains in total and one the nice features is bigger brush sizes then what you normally can use due to the height map settings etc.

The only down side for me anyways it lags quite a bit. I'm only using on a flat scene to test it since my entire projects pretty much flat but I thought I share some the feedback of it.

I'm going make some videos on it at a later date since I want to show it at it's peak and clearly your releasing new updates soon.

But it's a great start and I can see this tool growing to become a must have with any project.

 

Hi - the error has come back. I have just 2 terrains now. There are also these issues:
1. For 'raise/lower terrain' there is a height setting. is this the same as opacity? not quite sure why the name would have changed? Even on the lowest 'height' setting the height change is too much for fine adjustments.
2. When I hold ALT to rotate the terrain it carries on painting. This is a real pain!
3. It does not seem to be very good at joining the gaps between terrains - is there a trick to improve that?

On the test scene everything works..

 

What have you done to reproduce that bug?
3. You mean it's slow?
2. Ok we will add this in fixed version, I never used alt during terrain painting, so I haven't feel that is important, but if it is, we will add that.
1. Yes height is the same as opacity in first tool (we will also fix that). Ummm so you have big height max value, ok we will add smaller values. Temporary you could change 435 line in multiterrain editor script to:
newHeight = EditorGUILayout.Slider ("Height", newHeight, 1/100, 100);

 

Thanks for that _- I will change line 435 and look forward to the update on the ALT - is there another way of rotating I could use meantime?

Re the error, I started all over again just to make sure all was clean. I already have 1 terrain, so I added another. As soon as I started your tool I got the error. I think the gaps are to do with that as it works fine on the test scene. So as I paint height it doesn't seem to really work on the adjoining scenes together.

 

You have your terrains on different scenes?

 

No - its all in one scene! I mean that I can make this all work in your tutorial scene.

 

Thanks very much for sorting that out over a Skype call - brilliant service - we could do with more developers like this!

 

Ok all errors have been fixed, I will upload that today. We will also add this alt for rotation and change height name

 

I'm using Unity 5.3.0f4 and Multiple Terrain Brush 1.4.

I started a new scene, added two separate terrains. I am able to see the blue marker and make hills on two terrains. Only problem is that the terrain doesn't stitch at all.

Only errors I saw was this:

Code (CSharp):

1. ArgumentException: An element with the same key already exists in the dictionary.
2. System.Collections.Generic.Dictionary`2[System.Int32[],UnityEngine.Terrain].Add (System.Int32[] key, UnityEngine.Terrain value) (at /Users/builduser/buildslave/mono-runtime-and-classlibs/build/mcs/class/corlib/System.Collections.Generic/Dictionary.cs:404)
3. MultiTerrain.MultiTerrainEditor.GetTerrains () (at Assets/MultiTerrainEditor/Scripts/Editor/MultiTerrainEditor.cs:881)
4. MultiTerrain.MultiTerrainEditor.OnGUI () (at Assets/MultiTerrainEditor/Scripts/Editor/MultiTerrainEditor.cs:256)
5.

Suggestions?

 

Hi. This is what we fixed in 1.4.5 As I see it's available on asset store from today. Could you update your tool to 1.4.5?

 

Nice look, but what about terrains with different heightmap resolutions? For example, one terrain has 513, and neighbour has 2049 resolution. Whether brush will work with it?

 

Hi!
Sorry this is not possible. There will be problem with LOD too. Engine couldn't hold proper LOD in the borders when terrains resolution are different.

 

I have interesting issue. Ever since I updated to version 1.4.5 every time I log in to unity it shows this asset needs an update. I clicked and updated, the button turns into a download button (indicating it is updated) and all is ok. When I log out, and log in next day it shows it needs update again. What I done next was to delete the entire NatureManufacture > Editor ExtensionsTerrain folder then update. Had no effect though. Anybody have this issue with this asset or any other? What exactly causes this and how to fix?

 

Umm..., have you got more than one unity installed? I think I seen this kind of problem before, but I don't remember nothing more.

 

Thank You NatureManufacturer. I have 470f1 installed, but "Asset Store" folder is empty, as rarely use 4. I have 5.3.2f1 installed, and is where I update assets from. Just deleted the folder again and disc cleaned, refreshed asset store, downloaded again. Refreshed asset store (in unity editor) and it wants to update again. I have version 1.4.5 This certainly does not appear to be issue with asset, otherwise, by now, someone else would have posted. I am curious though, you do not need to, but if want to suggest ideas for me to explore, I will try things to figure it out. Maybe there is some thread in some unity forum area where I could post this to see if anybody else experienced similar, I have no idea where to search and post though. If I do figure it out I will post link to thread here. You have suggestion where I might post the issue?

 

Hi!
Do you know unity store assets that you downloaded in specific folder and when you click upload/import it don't download asset again but only import it from specific folder? Deleta asset from this folder.
In windows 7: C(disc with windows):\Users\USER\AppData\Roaming\Unity\Asset Store-5.x
When you click download it will load new asset from assetstore,instead use old one.

 

Hi!
We solved all performance problems at huge heightmap resolutions, also we optimize stitching so it will work 1000x faster now! Soon we will upload new 1.5 version! New version will be available in 5 days

 

Hi

I am wondering if this is compatible with World Composer (and its companion Terrain Composer)?

https://www.assetstore.unity3d.com/en/#!/content/13238

I use these two assets quite a bit but do find the idea of not having to select terrains one-at-a-time appealing.

Thanks.

 

Hi.
Yes, it work fine with Terrain and World Composer. I also use Nathaniel tools in my development
