Terrain Composer2 a next generation GPU powered terrain tool.

On your screenshot I can see splat output button is disabled (needs to be green). Hope that is the issue...

Nathaniel

 

Yes , now all is working. Thank you again

 

Does TC2 already work with Mac OSX?

 

no not yet,

Hi Nathaniel.
I'm testing with a large terrain (10x10 km) and when I'm texturing, my terrain shows a white squares.



To fix it, I need to change the "Basemap Distance" to 0 (zero) but your UI don't let me change to zero.

But the default terrain config editor of Unity, lets me to set a zero value.

** Is there any reason to not allowing the "Basemap Distance" be zero?

I changed the following code in the file "TC_TerrainAreaEditor.cs", line:442 and now I don't see white squares anymore.
if (currentTerrain.basemapDistance < 1) currentTerrain.basemapDistance = 1;

Best regards.

 

Actually the basemap distance needs to be very high...like 200000.

Hello Everyone,

I just made some documentation for Manual Object Placement:

Thanks so much!!!

 

Mac runs on OpenGL rather than Microsoft's proprietary DX. Unfortunately, Apple has abandoned OpenGL advancement and is moving instead to their own proprietary Metal standard. It's technically pretty good, but, well, just as proprietary as DX. :-(

The good news is that Metal supports (or soon will) compute shaders, and the Unity devs have publicly stated that they will incorporate that API into the Unity environment. Metal support is in the Unity runtime now, and "coming soon" for the Unity editor.

Until then, we Mac users are stuck at OpenGL 4.1, while you need at least 4.3 (iirc) to support compute shaders in OpenGL.

 

Hello Nathaniel, I was wondering how I would be able to get the latest version of TC. I bought the original off your website. Any help would be much appreciated.

 

Can you contact me by e-mail? (Nathaniel_Doldersum@hotmail.com).

How can i create multi tile terrain with TC2?

 

On your Terrain Area object, where you initially created your terrain, you can choose multiple terrain, and then press the create terrains button again

 

Nath's Doc's for MAC:

• TerrainComposer2 beta requires DirectX11 and does not work on the Mac yet. Because Mac OS does not support GPU Compute shaders yet. It requires OpenGL 4.3 and Mac OS is still on OpenGL 4.1. Don’t worry as I’m still working on CPU Multi-threading generating, and this will be added during the beta so it will also work on Mac and DirectX 9. Click here for more information about supported platforms for Compute Shaders in Unity. TC2 creates Unity terrain and the terrains them self can be used on any platform that support Unity terrains. So no DX11 required for a build.

Until then, we Mac users are stuck at OpenGL 4.1, while you need at least 4.3 (iirc) to support compute shaders in OpenGL.
Ty for replying, I have not used MAC in so many years nor support it .. So that is why I was unsure .So glad someone reply with the information. I don't use Unity that much for PC now a days, I use Unreal , Cry and other engines... I use Unity for Android, IOS and Windows these days... I used to do alot with PC for Android, but never MAC.

. Android still is not working, but after testing and talking to Nath he said that Android I believe does support Compute Shaders but it still has some bugs , so after testing it still gives no output, and this time I no longer get the error on console does not support Compute Shaders ... Just no out put ..I also made sure I had it in Android 3.0, tried them all just to see if I could get an output.. So far nothing... For the test I added a simple noise node only... and got no output.. I switched to Desktop and it worked as expected . Nath said he would test soon to see why.. I just wanted to post an update for any Android user ..So they aren't messing around...

 

Congratulations. TC2 is now the top grossing product in the asset store. That's quite an accomplishment.

 

How do I set grass density to anything but 1? I'm resetting it (both editor and runtime) on the Terrain Setup inspector. But when I then run my game I have way too much grass, and the value has reset itself again to 1. Thanks.

 

Hi, You can change the density in the terrains standard unity settings with the density slider. But be aware that will affect all the other densities. You can also (depending on your nodes setup) change density by playing with the scale gizmos and being a bit creative with noise maskes etc.

 

Hello. I would like to know how can I load a custom stamp in my terrain?I tried to save a jpg or png file and a separate file in raw(both from photoshop) after placing them in the right folders the TC2 is not making like on that picture for highmap. Is there some special settingds needs to be? Thank you

 

I can't place trees. I get tree index out of bounds and no matter what nothing affects the layer. Any ideas?

 

Thank you Seneral.
Not that it is hidden somewhere

 

Thanks , yes I'm happy about it.

I will take a look at it. But the best way to have lower density is to use a lower grass resolution. That will result in best performance.

It's very simple. You only need the raw file, TC2 makes automatically the preview image. You need to follow the steps in the documentation:
http://www.terraincomposer.com/terraincomposer2-documentation/#stamps

And here info how to make from WorldMachine:
http://www.terraincomposer.com/terraincomposer2-documentation/#frequently-asked-questions

Do you import the latest patch?
http://www.terraincomposer.com/terraincomposer2-release-notes/

Nathaniel

 

Tried it but it didn't help. I can place trees in other scenes but not the one i'm working on

 

How many trees did you use? Can you show a screenshot of TC2 window? And did you try click the 'Refresh' button?

Nathaniel

 

Another newbie question
How can I remove the hard lines in my terrain?

Some info:

• Terrain 20x20Km (just for testing/learning, pls don't ask why???)
• Stamps: just one, repeated 4 times.

[Screenshot of the terrain with hard lines]​

[Screenshot of TC2 config that produces the hard lines in the above terrain]​

Thanks so much!

 

tried 1, 2 and 3 tree models, no diffrence. Tried to refresh and this is how it looks like right now

 

It's because the stamp you use has edges, see the preview images of the nodes. You can either lower it or use a mask on it. Then you would need 4 layers with your setup.

Ah ok so on the very basic setup...Can you show me a screenshot of the Unity console with the error? (control-shift-c).

Nathaniel

 

I don't get an error in the console all I get is a message on the tc window saying "Tree index is out of bounds, index = 1015054416. Try the 'Refresh' button."

The message appears sometimes when I hit refresh but most of the time nothing happens. I've also noticed just before the message pops up the text saying how many trees is placed turns to 1 or 2.

 

Ah ok. What tree resolution do you use? Did you change it on the main Tree node?

Can you send me your TC2 prefab project file to Nathaniel_Doldersum@hotmail.com. To do this TC2 Menu -> File -> Save...Then in your project it creates a prefab, can right click it and export as Unity package (don't include dependencies).

Nathaniel

 

Haven't changed the resolution. All I did was follow your tutorial video and it didn't work so I didn't break anything before the problem occured. I could send you the prefab but it does work if I go into a new scene so you would probably don't find anything wrong there

 

Does this work on APU's? or only GPU

 

This is a bit off-topic but I thought I would share the link to easily search inside 92 pages of terrain composer forum only.

http://forum.unity3d.com/search/1971443/?searchform=1&t=post&o=date&c[thread]=151365

It may be nice a addition to post number 1, unless this is common knowledge. I just discovered how to do this very recently. Hopefully it saves some new users some frustration when trying to search.

 

Hi Nathaniel, does TC2 work with the current version of WC?

 

Hello!
Love That tc2 is coming out!! But before ugrading i was wondering how the workflow with gaia is like? I says i was thinking about using tc to make the base of my terrain (i'm maring a linear level) and then add specific details manually using gaia but I'm worried this might be a destructive workflow because if I want to make a change in tc2 i might lose everything i changed with gaia.

 

How to create a really big terrain with TC2?

Hey Nathaniel,
I know that that question has been asked here and answered before.
But considering the new workflow of TC2, could you give us some advice on creating a big... big terrain (a terrain that includes trees, grass, objects)

Thanks again for been so helpful.

 

I can't seem to get the terrain height to work for the splat maps. It only shows black.



Angle works though for the same height generator.



I'm using perlin noise to generate the height.



I tried to look at some of the demo scenes but it seems they all have animated height maps and none of the splat maps are generated by terrain height.

 

Does Unity or TC2 have problems with heightmap resolutions of 4k on terrain tiles? When I go 4k the seams of the terrain tiles get all distorted like the jagged edge of a knife. 2k and below it's fine though.

 

I have this question as well. I bought WC quite a while back and hadn't really used it. I'm trying to now and having no luck (the video show creating 16x16 - is that realistic?).

 

16x16 is no problem. If you are not getting 16x16 then you can click the resolution - and + buttons inside world composer "Image Export" window after setting your zoom to max (normally 19).



I started a 48x48 this morning using world composer (and terrain composer 1) so I can mess around with World Streamer.

EDIT: oops, wrong forum

 

I will dig into this, it probably has to do with terrain size, did you change anything there?

If the APU supports DX11 and Unity supports it then it should work. But I can't find any info on this are you using a APU with Unity?

Yes it does. You can directly use the exported heightmaps from WC as stamps in TC2.

What kind of details do you want to add with Gaia? GameObjects? And why you still need Gaia? It is possible as in TC2 you can just disable an output and TC2 won't touch it. That is for trees/grass as they share Unity terrain. Nut for GameObjects its completely separate, so you can use any spawn tool and it won't interfere with TC2.

Depends how big. There's limitation on Unity terrain total resolutions (of all terrain tiles together) and performance. I don't recommend to go higher then 4k heightmap, the best technique to make a heightmap look more detailed is using a higher resolution global normal map on each terrain tile. In beta 7, TC2 can automatically generate a high resolution normal map and assign it the new included TC2 terrain shader that has added global normal and colormap. It will also work out of the box with RTPv3.

Basically it's very simple select like 5x5 terrain tiles in TerrainArea GameObject, and click 'Create Terrains' button. Then in size you can change the size for each tile. So if you make x and z 4000, your total terrain will be 20 x 20 km. For the rest the work flow is exactly the same as I show in my tutorial video with 1 single terrain. TC2 will automatically generate on all terrain tiles, like TC1 would do.

Terrain height node should work, I use it in the tutorial for placing splats/tree/grass and rocks, to not have it spawn under a certain height where the water should be. Maybe there's an issue with it on your side, but probably because the terrain I see in your images has low height and you need to enable the 'Active' toggle on 'Local Curve' in the inspector if you select the node. Then to easily change the output of the node you can drag the min-max slider, and with the curve you have more control. If you drag the left min-max slider to the right, black gets more black and the right min-max slider white gets more white.

It should work, can you show a screenshot? How many terrain tiles do you use? As 4k is on the high side for performance already for 1 terrain tile.

Can you explain in more detail what your issues are? Yes WC can do 16 x 16, in which video I show that?

Nathaniel

 

Nathaniel
could you please post the download links of patch 5 & 6?
I can't find them in the forum.

Thanks.

 

I'm doing 8x8. It looks fine at 2k with no problems. And the jagged edges are only on some terrain tiles, not all.

 

The video is

at about 8:12 in. However, I've found that I can create/export height maps just fine. The problems come from trying to generate terrains directly from WC. I don't really want/need to do that at the moment though so I'm not stuck.

 

Here's the latest patch:

Must be a rounding issue. Did you install the latest patch?

Nathaniel

 

For some reason my Unity doesn't automatically change the terrain when I drag a capsule around. However, if I change the mask by clamping it or flipping it etc. then (and only then) does it change the terrain based on the capsule.

Any ideas?

I'm using newest non-beta Unity3D in DX11. Windows 10, 64-bit etc.

 

Yeah I updated yesterday, still no luck.

 

You have to add the TC_AutoGenerate script to the capsule

Nathaniel

 

That did it! I don't know if I missed that in your documentation or if it actually wasn't in it. Question though, what does the "repeat" checkbox do?

 

@Nathaniel,
I am interested in using TerrainComposer2 for creating my own flight simulator for Oculus Rift. Would you recommend getting UnityFS, World Composer, and perhaps any other tools that you might recommend. Initially, I want to focus on terrain with trees and minimal buildings with some lakes. I would like to fly low in a helicopter.
I have an i7 (6 cores)running at 4.3Ghz and a Nvidia 970 - should I be able to expect 75->90fps as long as I don't make settings too high. From your one video above, it sounds like that is something you have tried. I am a newbie with Unity - do I simply want to start with an OVRPlayerController and then add the terrain? Do you perhaps have a single demo terrain for me to try out?

Thanks much

Dave
