TriLib - Model Loading Package

I will test using your Unity version and answer here.

 

Thanks

 

I've tested on the same Unity version as yours and got no issues....
Could you check if all plugins inside the "Plugins" folder are enabled for "All Platforms"?

 

@rickomax

I need to keep the models in the app after downloading. After exiting and returning.

 

@rickomax I was still not able to sort my problem out I have tested it on many different phones and different versions of Android now. Using the default AssetLoader scene I can't load a model on the phone the app works but it doesn't show any files to open. It worked on the first few builds. But when it worked it used to ask for permissions to access files and it doesn't do that on any of the new builds.

 

YEs they are all enabled

still getting that issue

only way to fix it is reimport but i cant do that every time

Thanks

 

Hi!

Does it happens when you import TriLib to an empty project?

 

Hi!

You could save them on a local folder and load them again with TriLib, but the best option would be serializing/saving them to a custom format which you could load faster.

There are some open-source options to do that, but you may have to tweak them to work for your needs:
https://github.com/Mcklem/JSONGameObject

 

I'm checking it out.

 

Thank you. Do you have a estimate of when I can test it again?
Keep up the good work

 

I will check it out. I’m downloading the models at runtime. So hopefully it’s possible to save them With serializing.

 

Any news on the problems loading multiple large texture maps.

 

So to update, do we just import the new package over the last one?

 

For TriLib 2, yes. You can't update TriLib 2 over TriLib 1 as they aren't compatible.

 

I've fixed some issues with the PNG textures reader. If your textures are on PNG format, that may fix your issues. I'm working on another fixes and gonna update the beta version soon.

 

Sorry, not yet!
I've been pretty busy lately, but I'm slowly organizing the next TriLib 1 update.

 

Hi,
Is it possible to save loaded 3D models as prefabs on the Resource folder for example so I could allow players to use those prefabs later?

 

Rgr that

 

Hi,

recently i bought TriLib for Unity. Could you please advise me how to download .fbx file from server with texture (or .obj with .mtl)?
i am developing on mac for iOS. and it works fine while importing same model from local storage but not from server.

 

@rickomax any idea?

 

What script are you using to download?

 

Hi

thanks for reply.
I am using sample from TriLib import which is: Scene1 - Asset Loader.unity
There are two options. First one to load data from local storage - which works fine. Second, Load Remote Asset (URI) which correctly download and display model but texture is missing.

If you want me to copy paste code from sample please let me know.

Thanks!

 

TriLib 2.0 beta version updated:
OBJ loader fixes.
STL loader fixes.
Added automatic alpha material checking.
Added URI downloading and updated sample.
Misc fixes.

Hi!

Loading textures from the downloaded model works as long as your model is inside a ZIP file.

 

Hi,
this the error I got, building for webgl with trilib 1.9 on Unity 2019.3f1. any idea ?

Hi richomax !

• Initially I used trlib 1.9 version in my project. Now i tried to replace it with trilib 2.0(beta version)as you suggested it does not replaces the old version. New folder was created in name of TriLibCore.
• I have called the LoadFromFile() in the trilib 1.9, but in trilib 2.0 it is renamed as LoadModelFromFile() with different parameters. I am unable fix the issues with this new parameters and I kindly look forward for your help.

It would be helpful, if you suggest how to fix this issue.
Thanks in advance .

 

You have to get rid of 1.9 all together 2.0 is a different build all together. Going forward you can just overwrite it when updating. After you install 2.x

 

@rickomax Thank You

 

Hi Rickomax,

Can you show me an example of a collection of models being loaded in at once, please

Howdy! I was wondering if it's possible to configure TriLib to ignore attributes and nodes in X3D files during the initial import process. Assimp and TriLib don't like the model I'm currently using for testing and I get this error:

Exception: Error loading asset. Assimp returns: [Node <Shape> has incorrect attribute "render".]

TriLib.ThreadUtils+<>c__DisplayClass0_1.<RunThread>b__1 () (at Assets/TriLib/TriLib/Scripts/Extensions/ThreadUtils.cs:57)

TriLib.Dispatcher.Update () (at Assets/TriLib/TriLib/Scripts/Extensions/Dispatcher.cs:79)

Likewise, I get this error for files that include a DepthField node. However, if I remove these attributes manually in a text editor, the X3D files import fine. With that in mind, is there a way to define a list of attributes and nodes to ignore during the import process?

 

Does anyone succeed to compile trilib for webgl ? Which Unity version should be used & settings ?
Thanks !

 

Ricardo can correct me if I'm wrong, but it doesn't work in Unity 2019:

WebGL:

Unity 2019 is not supported at the moment. We are working on a solution for this issue.

Unity support link: https://fogbugz.unity3d.com/default.asp?1163092_ata4ac2o89voc2fn

https://ricardoreis.net/?p=127

 

zip file do not work either, i have a zip with 2 files in it but only loads 1 of the files

 

TriLib is useful but you can end up with a big tree of transforms and multiple meshes (even with combineMeshes set to true). Is there an easy way to combine all this into 1 game object with no tree of parts?

 

Downloaded the latest update but still having trouble with texture mapping. PNG or JPG files both don't seem to load properly.

Perfect. Thanks!

it worked out for .obj model but i am still facing issue with .fbx file texture. Any suggestion?

 

Thank you All_American for your kind reply
I have tried to replace the trilib version but i could not. Sorry , I can't understand what you said in previous reply. Could you explain me in detail, how to replace the trilib verion 1.9 to trilib 2.0 (Beta Version) in my project.
Thanks in Advance..

 

In your project delete all the trilib files/folders and then instasll the trilib 2.0. Make a back up first.

 

Hi!

I'm working on TriLib 1.9.0 to even it with current Assimp branch, I'm also making some changes to make the code basically the same as Assimp one, so updating TriLib Assimp version will be easier.

 

have the iOS issues been fixed?

 

Not yet, but I will re-test every platform before the new 1x update, which should come next week.

 

Do you know if the textures are embedded or external files? If external, they should be at the same folder as the model.

 

You can solve this by manually linking the Trilib iOS library files in XCode. For some reason they are not anymore linked automatically.

EDIT: The reason is the line 133 in TrilibCheckPlugins.cs, which apparently should end with something like

? "release.a" : "debug.a";

or it will not choose the correct versions and just disable all iOS dependencies. After this change the correct files are included and XCodes builds the project fine.

 

The next TriLib update changes how the iOS plugins are handled.
You will be able to switch from IOS Device to IOS Simulator on TriLib Settings area.

 

That sounds great, the more straight forward the build process is, the better!

Another thing, if anyone wants to use TriLib 1.9.0 with Unity 2019.3 and iOS, you need to make the following change to the same TriLibCheckPlugins.cs in order to set the correct XCode settings:

 

#if UNITY_2019_3_OR_NEWER

                var targetGuid = pbxProject.GetUnityFrameworkTargetGuid();

#else

                var targetGuid = pbxProject.TargetGuidByName (PBXProject.GetUnityTargetName ()); //Original line

#endif

 

Hi All_American !
I have done what you have said in Previous replay . But inTrilib 2.x there is no function named LoadFromFile() , it was renamed to LoadModelFromFile() with new parameters. How can i call new function with new parameters from my old code.

 

Olá Ricardo, tudo bem?

Eu te mandei essas dúvidas por email, mas não tive retorno.

1 - Estava fazendo uns testes e tentei importar um arquivo .glb
As cores em si veio tudo certo, mas o alpha não foi aplicado, sendo que num arquivo collada(.dae) o alpha é aplicado. Isso seria algum bug no trilib ou é problema do arquivo em si que não tem essa opção?


GetAssetLoaderOptions:
var assetLoaderOptions = AssetLoaderOptions.CreateInstance();
assetLoaderOptions.DontLoadCameras = false;
assetLoaderOptions.DontLoadLights = false;
assetLoaderOptions.UseOriginalPositionRotationAndScale = true;
assetLoaderOptions.ApplyColorAlpha = true;
assetLoaderOptions.ScanForAlphaMaterials = true;
assetLoaderOptions.AddAssetUnloader = true;
return assetLoaderOptions;

2 - Eu queria verificar a cor do material no OnMaterialCreated, pegando o material, mas ele retorna sempre em branco (1.0, 1.0, 1.0, 1.0). Vi que não existe a propriedade _Color quando entra nessa função. Precisaria ativar alguma coisa no AssetLoader ou algum problema com a TriLib?

assetLoader.OnMaterialCreated += LoadMaterial;
private void LoadMaterial(uint materialIndex, bool isOverriden, Material material)
{
for (int i = 0; i < material.GetTexturePropertyNames().Length; i++)
{ Debug.Log(material.name + " : " + material.GetTexturePropertyNames());
}
Debug.Log(material.name + " : " + material.color);
}

 

I haven’t looked at that code yet. But it’s gotta be easier than the download from internet one.

It was hard for me to understand it but once you work through the examples it will become clear.

Use the example.

 

Hi!

I've updated TriLib 2.0 beta version.

Download link for existing users:
https://ricardoreis.net?p=217

Changelist:

• Misc fixes.
• Added non-default pipeline materials usage to the package (work in progress).
• Added STL parser (work in progress).
• Added initial GLTF 2.0 parser (work in progress).
• Changed material creation pipeline to allow checking alpha pixels and fixing normal maps automatically.

Regarding TriLib 2.0 usage, since it's a beta version, I haven't written any docs yet, besides some docs you will find on the sample scene scripts, the usage should be pretty straightforward when copying the code from the sample.

I apologize for 1.9.1 legacy update, which should come with the latest Assimp fixes.
The legacy update should be ready soon, I will answer the e-mails as soon as I have the 1.9.1 update out, so we can remove already fixed issues from the way.

Best regards,
Ricardo Reis.
