Assets AltTrees System [WIP] [AssetStore]

Have you marked small shrubs and other small objects like "Is Object"?

 

Thanks for letting me know. Is that going to be a feature in the future for ultra large terrains?

 

Yes, I plan it.

 

I have not, I'll try that.

 

Hi is there a way to disable the gameobject tree for tree chopping? What happens is if the health is 0 it disables the gameobject for some secs before it respawns by turning it back on... the colliders are working but the tree still stands

I have all my trees and plants set as gameobject

 

Hi,
If I correctly understood the question, to remove a tree you can use the following function: AltTrees.removeTrees

 

Hi! I'm getting these errors & have no idea what they're referring to. Any advice?

 

I don't want to delete the tree, only I want to disable the game object or turn off the renderers.

I'm wondering I'm placing my trees as game Objects and not trees, can I just drag the new alt tree gameobject to the terrain to use or do i have to use the alt trees manager to use your system.

Thanx Jim

 

Sometimes when I deselect AltTrees and select it again a "Working...Please wait..." Progress bar pops up and takes forever, sometimes more than 30 minutes. The most annoying thing about it is i can't do anything else because Unity takes Focus every few seconds.

 

This fails on build with:

Assets/Plugins/AltSystems/AltTrees/Scripts/AltTreesPatch.cs(2016,32): error CS0103: The name `AssetDatabase' does not exist in the current context​

Ideas to fix this anyone?

 

Hi,
Sorry for late answer!
Did you edit this file manually earlier? "Assets\Plugins\AltSystems\AltTrees\DataBase\AltTreesDataLinks"

 

You can only disable rendering of all trees (make the manager object inactive).

It is necessary to place trees through the manager.
You can import your objects into the manager using this: Import Trees from Scene

 

This happens when the terrain size in the scene changes.
Do you change the size of the terrain? How many terrains in the scene? What is their size?

 

Find the 2014 line in the file "Assets/Plugins/AltSystems/AltTrees/Scripts/AltTreesPatch.cs".
Replace it

Code (CSharp):

1.                         if (treesNoGroupData != null)
2.                         {
3.                             pathStr2 = AssetDatabase.GetAssetPath(treesNoGroupData);
4.                             if (pathStr2 != "")
5.                                 bytesTemp3 = File.ReadAllBytes(pathStr2);
6.                             else
7.                             {
8.                                 bytesTemp3 = treesNoGroupData.bytes;
9.                             }
10.                         }
11.                         else
12.                             bytesTemp3 = null;

on this

Code (CSharp):

1.         #if UNITY_EDITOR
2.                         if (treesNoGroupData != null)
3.                         {
4.                             pathStr2 = AssetDatabase.GetAssetPath(treesNoGroupData);
5.                             if (pathStr2 != "")
6.                                 bytesTemp3 = File.ReadAllBytes(pathStr2);
7.                             else
8.                             {
9.                                 bytesTemp3 = treesNoGroupData.bytes;
10.                             }
11.                         }
12.                         else
13.                             bytesTemp3 = null;
14.         #endif

 

Yeah this was after splitting the Terrain, a 2048mx2048m into 1024 64mx64m Terrains. I ended up killing Unity and reloading. I regenerated the trees on the original Terrain again, converted them to altTrees, made a prefab of the altTrees manager and used that in the gamescene where I stream my Terrains. Works perfectly and faster than waiting on that progress bar.

 

Aha, yes! It was causing some source control issues, so I reverted it to an earlier version. That seemed to help, but I guess it was a bad idea. Is there any way to fix this?

 

Hello Diab1O,

I'm very interested in this tool! It looks great, but I'm wondering if there are any updates regarding Map Magic? Is Alt Trees and Map Magic incompatible?

Thanks!

 

Select this file in the editor. It contains 3 arrays. You need to make them the same length.

 

Hello,
At the moment they are not compatible, but I plan to fix it.

 

Thanks! that worked perfectly.

 

I bought your system with the intent of using it but then discovered that it is Windows Only - please consider looking at resolving this as there are few desktop commercial games where only a single platform is supported. Most of us build for Windows, OSX and Linux and therefore a solution like this just gets dismissed immediately as of no use. I'm an indie developer the same as you are, I had to buy a mac to build for Mac's but the investment was more than worth it in sales.

 

Hello,
Can you tell me the problem? What does not work?

 

Im getting a very annoying error with Unity 2017.1

"InvalidOperationException: Material needs to enable instancing for use with DrawMeshInstanced."

PLEASE FIX!!!!! Any Ideas?

 

I was going by the comments of a previous forum message where the person was unable to get it working with OSX and your response was that you couldn't work on it as you don't have a Mac ..... has the status changed?

 

You need to install the latest version of AltTrees, for Unity 5.6.0+

No, it has not changed. I do not have any other platforms than Windows. If you say what errors you get - maybe together we can find a solution.

 

imported package. installed. opened demo scene and:

AltTrees: dataLinks.getId(prototypes.tree) == -1. (9810294)

clean project

 

This is a false mistake, do not pay attention. It appears only when you first open the demo scene.

 

got it

 

Hey @Diab1O I'm getting the same error as @Ninlilizi when trying to build.

Code (CSharp):

1. Assets/Plugins/AltSystems/AltTrees/Scripts/AltTreesPatch.cs(2016,32): error CS0103: The name `AssetDatabase' does not exist in the current context

and

Code (CSharp):

1. Assets/Plugins/AltSystems/AltTrees/Scripts/AltTreesPatch.cs(2016,21): error CS0103: The name `pathStr2' does not exist in the current context

Any ideas?

 

Hey,
Please look at this post:
#post-3138186

 

OMG I'm blind. Thank you.

 

You are welcome

 

Does AltTrees Support Grass meshes as well? i made a normal map with regular unity terrain builder- was getting great FPS, then i added more grass- and the FPS is Terrible. Will this be able to resolve my issue using your AltTrees systems to export my tree's and grass mesh. Also one last thing if my Trees already have LOD's will you system detect that. Thanks, really interested in purchasing if this is possible

 

Hello,
AltTrees improves performance due to the system of far billboards. If your grass is far visible - maybe it will be better.

 

so would the trees and grass i have look the same but with better performance- with your tool. hope this screenshot of my game shows

 

trees broken after hit play. it happens if i import trees from existing terrain. spam of errors:

InvalidOperationException: Material needs to enable instancing for use with DrawMeshInstanced.

dont know what was that errors. but now seems all ok.

there is aother problem. in VR alt trees doesnt help anymore. in fact 10000 trees on terrain faster then 10000 trees imported to alt trees from terrain.

EDIT:
generated trees by alt tree dont have instancing option ON in material. checked it and magic happened.
keep testing it.

EDIT 2:
all broke again after i clicked "update billboard texture and refresh scene" button in alt tree.

found out that instansing option not turn on in bilboard materials. this is causing error spam and unvisible trees (billboards still can be seen). if i turn ON instancing manualy, then all trees generating but fps insanly slow.

 

Hi,
I think you have an incorrect version of AltTrees.
What version of Unity and version of AltTrees?

 

alt trees 0.9.8.1
unity 2017.1.0f3 personal

 

Open the "Assets\Plugins\AltSystems\AltTrees\Scripts\AltTrees.cs" file. Find the line with the code

Code (CSharp):

1. static public int altTreesVersionUnity =

What version is written? Should be 560

 

yep, it is, line 13: static public int altTreesVersionUnity = 560;

 

Hello,
Sorry for late answer!
Open the file "Assets\Plugins\AltSystems\AltTrees\Scripts\AltTreesManager.cs", find line 2780:

Code (CSharp):

1. #if UNITY_5_6

Replace it with this one:

Code (CSharp):

1. #if !(UNITY_5_2 || UNITY_5_3 || UNITY_5_4 || UNITY_5_5)

The error "InvalidOperationException: Material needs to enable instancing for use with DrawMeshInstanced." will disappear.

 

Hi i need to populate terrain with trees on runtime with my generator, will i be able to do it?

 

Hi,
Yes, look please API: http://altsystems-unity.net/AltTrees/API/

 

This is runtime generated, these are prefabs, i need to know if
1. I can delete trees on runtime easily with a delete tool
2. I can save the state on runtime.
(or at least you have exposed the DATA that i can save myself, shouldnt be that hard to make a list or whatever data structure youre using public, eh?)

 

I have a question. I'm using a mesh for a terrain in my project, I use it because I can't move unity's terrain at play time. My my project has a large terrain and I move the word to the origin so I dont have issue with float point accuracy. I use The AltTrees system for my large map and it works great, I just have a small problem, you see when I reset the origin I move the my terrian mesh. The problem is , when I "reset" the trees don't, they stay. I was wondering if there was a way to move the trees along with my terrain mesh , If you know a solution please let me know. Thanks again cheers.

 

you can move terrain if you uncheck "static" on it

 

Not on play time.

 

Yes on play time
https://twitter.com/pointcache/status/861141043256938497

as i said, unmark as static, and move all you want.

 

Yes

No, at the moment it's impossible.

Please look at the script "FloatingOrigin" in the demo scene on Camera.
