TriLib - Model Loading Package

Thank you.

I think I may have tried updating the 2.0 with the 1.9 still installed. Then I deleted the trilibCore folder.

Would that screw my install up?

 

Could I please get a reply to my question?

 

@rickomax This is a large issue which is blocking the development of my application. What could be causing this? I assume I'm not the only person to have tried loading in several models at the same time.

EDIT: After a short round of testing I don't seem to get the issue when running as a packaged build but I may just not have tested enough.

 

I'm still having issues with the second model I download/import going into the root of the first model that was downloaded/imported.

 

Hi,

So have Unity AR project with following specifications
unity version 2019.2.6
Xcode version 11.1
the latest version of Trilib 1.9.0
macOS Catilina


It has Unity packages such as AR Foundation, ARKit but after importing Trilib asset we are getting the following error during the build in XCode

Ld /Users/nikhilsawlani/Library/Developer/Xcode/DerivedData/Unity-iPhone-dqcelmuwynjiazemfugtomfqcmru/Build/Products/ReleaseForRunning-iphoneos/mapping.app/mapping normal arm64 (in target 'Unity-iPhone' from project 'Unity-iPhone')

cd /Users/nikhilsawlani/ARWAYLTD/xc

.....
d: symbol(s) not found for architecture arm64
clang: error: linker command failed with exit code 1 (use -v to see invocation)

We are using the Sample AssetDownloader script for loading model in iOS and Android

I also tried the new BETA plugin 2.0.1 but it has lots of missing dependencies for AsseTDownloader.cs

Please help

 

The beta has been updated with fixes + Zip asset loader.

Download at: https://ricardoreis.net/?p=217

 

Nop, they're extracted on different folders and uses different namespaces.

 

Hi!

What's your Android device specs?

 

Hi!

Are you able to upgrade to TriLib 2.0?
The feedback to fix issues on this version is faster than TriLib 1.9.0, which should be discontinued soon after 2.0 be released.

 

@rickomax can you please reply to our build issue as we are on a deadline of the project

 

Could you try the latest update?

Could you please point me out whats your issue again? I'm sorry, I get many requests per day.

Hi!

Beta 2.0 shouldn't be missing any dependency, but I haven't tried it on my iOS yet.
I will be testing it on OSX and iOS now and see if we need to add anything else to the package.

I will post the results here in a few hours.

 

When I tried there are no issues with the build-in 2.0 but when I added AssetDownloader.cs from 1.9.0 has many missing dependencies so please let us know how we can use 2.0 to load models in IOS from web links

 

Ah, ok.
TriLib 1x and 2.0 code aren't compatible.
I will try to port AssetDownloader to 2.0 today.

 

I've updated the beta version with the AssetDownloader class.
Please check "AssetLoaderTest" scene and script for usage.
Download at: https://ricardoreis.net/?p=217

 

Not yet @rickomax

I will and keep you posted.

coukd you tell me why the models keep overwriting each other?

man I doing something wrong?

 

Just sent the files to you, hope you can find something.

Regards

 

Any documentation on how am i supposed to name textures for them to be loaded ?
Currently they are in the same folder as model and i'm using .LoadFromFileWithTextures() method.

 

@rickomax Thanks for the reply it's just a Samsung j5 Prime Android version 7.0 the thing that is confusing me is that the first few builds worked perfectly on this phone until I added a slider to rotate the light source. I don't know if I maybe changed a setting or something that 8 wasn't supposed to.

 

Hi, I have tried upgrading to version 2.0 however the plugin won't compile on my version of Unity. I'm using Unity 2018.4.13f1 for this project and I get an error from AssetLoader.cs on line 706 which says that Mesh.Optimize() is deprecated.

 

Much less code to deal with. I am trying to pluck out what I need. I don't want to use GUI.

Am I suppose to make a prefab out of AssetLoaderTest and instantiate it?


If I run your example it still downloads and overwrites the previous downloaded model.

Edit: I got it downloading good. it's not overwriting.

Not sure if I am doing it right though...but it works.

 

My camera is rotating 180 degrees when the models import.

 

@rickomax for the time being I have commented out the call to Mesh.Optimize() to test the plugin works however I am having issues now with the textures and materials not loading. My Unity log is filled with messages such as "Unkown property type: double" and "Unkown property type: ColorRGB".

EDIT: bool is another type which is not recognised by the loader in ProcessMaterial

 

Please send your models for testing to: contato@ricardoreis.net

 

updated version the embedded textures don't get applied to the materials when loaded in

also it also only correctly renders the last material and ignores all other materials, meaning they are not visible

 

Answered your via e-mail and updated the beta version.

 

Could you download the beta again? I've just updated it.

 

The beta-version has been updated with a small fix on the test-scene.

 

Get a lot of errors trying to do a sanity build with vuforia + trilib async model load example for iOS (Unity 2019.2.2f1)
works fine in editor - all kinds of missing symbols in iOS _aiLight_GetColorSpecular etc

Hello, I got the same errors as @ina when I try to build on xcode... 100+ errors.

 

Hey. Yesterday bought a TriLib package. The build on Android in Unity 2018,4,1 works fine, otherwise I have a few questions.
1.Unity build 2019.3 slightly breaks the uploaded models that displayed perfectly in 2018,4,1
2. The application could not be assembled on ios, an error in the screenshot in the letter
I will be very grateful to the feedback and have a nice day

 

hi @rickomax, I was using version 1.9, but I was having the same error that happened with Niksasaw:
"d: symbol(s) not found for architecture arm64
clang: error: linker command failed with exit code 1 (use -v to see invocation)"

Now I'm using beta 2.0, but it looks like AssetLoader.LoadFromMemory(bytes[], ...) no loger exists, so I converted the bytes[] to MemoryStream to use AssetLoader.LoadModelFromStream(Stream, ...), but it's loading just an empty gameobject.

 

@rickomax

Update is awesome. Did you update it again after you told me to update it?

On import my camera if flipping 180 degrees. Any idea what could be causing this?

 

Hello all,

I have used the trilib plug-In in my unity project to load a 3D model file at the runtime.
But my hierarchy structure get changed, by creating the assembly nodes.
How can i remove these nodes ?
It would be helpful, if you suggest how to fix this issue.
Thanks in advance.

 

Hi again.
I'm sorry for the late reply.

Here is an example:
1. Original data as displayed in BIM Vision 2.2


2. Data we get from trilib:

Notice that some data is not even there and other seems to have "garbage" values.
Maybe I'm doing something wrong? Or maybe assimp is not behaving properly?

Thank you for your time.

 

Hi!

I will be testing TriLib1x on iOS as soon as possible.
I will keep you updated on this thread.

 

Hi!

I will be checking out iOS issues as soon as possible, regarding the Unity 2019 issues, if you be able to send the models you're testing to contato@ricardoreis.net, that would help.

 

Whats the file type you're trying to load?
Are you getting any error message on the console?

 

Models orientation should be ok, you should get the same result from FBX Review or FBX Converter preview on TriLib, if it's different, please send me a message here.

 

I'm almost sure that's an issue with Assimp data parsing.
I'm updating TriLib Assimp version to match their actual version and simplify the updating process.

 

@rickomax

My camera isn’t part of the model download. It’s the scene main camera. It’s not connected to the download at all but flips 180 degrees when the asset loader starts.

 

Having issue with embedded textures not setting the textures in unity

only MainTex is working
normal, metallic not working

Any ideas why

 

@rickomax

It's a .obj file, has no error message, and it loaded with 1.9, now with 2.0, it creates a gameobject only with AssetUnloader.

Code (CSharp):

1.  
2.     private void LoadModel()
3.     {
4.         ...
5.         MemoryStream streamData = new MemoryStream();
6.         streamData.Write(decryptedData,0, decryptedData.Length);
7.  
8.         AssetLoader.LoadModelFromStream(streamData, "obj", OnLoadModel, null, OnProgressModel, OnErrorModel);
9.         ...
10.     }
11.     private void OnProgressModel(float value)
12.     {
13.         Debug.Log("loading: " + value);
14.     }
15.  
16.     private void OnLoadModel(AssetLoaderContext assetLoaderContext)
17.     {
18.         //If the root game object has been loaded.
19.         if (assetLoaderContext.RootGameObject != null)
20.         {
21.             loadedGameObject = assetLoaderContext.RootGameObject;
22.             Debug.Log("loaded");
23.         }
24.         //Displays the number of models loaded.
25.         Debug.LogFormat("Model loaded: {0}", assetLoaderContext.Models.Count);
26.     }
27.  
28.     private void OnErrorModel(object context)
29.     {
30.         //Casts the context into a ContextualizedError.
31.         var contextualizedError = (ContextualizedError)context;
32.         //Safely converts the ContextualizedError context into an AssetLoaderContext (some errors can be thrown when the context isn't ready yet).
33.         var assetLoaderContext = contextualizedError.Context as AssetLoaderContext;
34.         //Destroys the RootGameObject from the AssetLoaderContext in case of partially loaded models.
35.         if (assetLoaderContext != null && assetLoaderContext.RootGameObject != null)
36.         {
37.             Destroy(assetLoaderContext.RootGameObject);
38.         }
39.         error = true;
40.         loadedGameObject = null;
41.         //Displays the error message on console.
42.         Debug.LogError(contextualizedError);
43.     }

 

In the options you can uncheck adding an unloaded.

 

Could you send it to: contato@ricardoreis.net ?

 

been a few hours - any update

 

@rickomax

I commented out the line where you fit the main camera to the import. I'm all set.

 

Any one else getting this error and how to fix it very annoying

Unity Version 2019.1.2f

 

8 and 16 bit textures are not working either
