TriLib - Model Loading Package

Its .net instead of .com

 

Thank you Mese!

 

@Mese96 thank you a lot, the offset fixed it for me completly

 

Hello, I have some questions. In the example Scene8 - Custom IO asset loading scenario, you can use "private const string objdata =" mtllib " cube.mtl \n\nv -1.000000 -1.000000 1.000000\nv 1.000000 -1.000000 1.000000\nv -1.000000 1.000000 1.000000\nv 1.000000 1.000000 1.000000\nv -1.000000 1.000000 -1.000000\nv 1.000000 1.000..... "Successfully loaded a cube. I want to know how to convert my model into such a string. Does trilib provide such API?

 

@Mese96 upon further testing i dicovered that Meata data is not really complete when comparing to other IFC viewers like BIM Vision. Is your data being displayed completly?

 

I did not test enough to confitenly say yes or no. Also my IFC knowledge in general is very little. Just enough to realize that no meta at all can't be right
But one thing that I discovered, the IFC Metadata is only strings.
Is this the same with your modells ?
(The aiMetaType)
Maybe the mentioned offset is not always needed ?


One more thing, I got an crash from assimp if I tried to load an ifc model with an Ü in its name, after replacing with an U it worked. (Probably Ä and Ö wont work as well)
If you get the same problem, and/or an solution also keen to hear about it.

 

Hi @rickomax,
I'm using Trilib v1.9 and want to load model with embedded materials and textures. Is it possible with v1.9, and how can i archive this.

 

@Mese96 yeah, my importer won't even load any file with ä,ü,ö in it, so "Umlaute" are a big no no.

I do have other data types besides strings in the ifc model, but they are being reasd correctly as well, it's just that some stugg ist being read... I am not sure if it is due to the structure of the file. But I as well don't know much about ifc.

 

@night_cat97 Then again, I can load the file in assimp directly if I format the string in UTF8, can be probably also be fixed if the string is differenty marshalled, but without c++ access thats out of reach.
As I am in holidy this and next week, it will take some time until I do more test.
Did you get any answer from @rickomax ?

 

Hi,

I am having the same issue, @rickomax was there a solution to this?

Thanks.

 

Hello, have you successfully implemented it in hololens? Are you using version 2.0?

 

Did you ever get an answer/solution for this?

 

Hi All
have this problem. WHen I try to compile for iOS Unity says that
Trilib doesn't support Bitcode and will be disable

Anyone has a solution to solve this problem?
I'm in unity 2019.1 and xcode 11.6 for an application that run on iPadPro
Thanks. This thing is driving me crazy

Paolo

 

it seems there are two problems:
- during export to AndroidStudio I miss assimp lib. Which library I need tp add to AndroidStudio project?
- there is also a marshalling problem with IL2CPP

Only two word: Help me
Thanks

Hello, did you test that trilib can load the model normally on hololens2? I'm using trilib1.9 now. It can't load the model. Can only the latest version of the plug-in be loaded?

 

Hi i have Trilib 2.0 Beta 17 and try to get it working with Unity 2019.4 WebGL, sadly something seems not to work. i can start the download but its never finished.

Working ThreeJs Mesh:

not working Unity WebGL Build:
http://webgl.sideeffects.ch/paul/UnityWebGLModelLoad/

both are trying to download the same model.(Press Space to start the download)

The Same problem with textures

 

Hi I am working with Trilib 1.9.0b - Hotfix and Unity 2019.4.8f1. I am facing a problem loading GLTF or GLB files with Trilib in Android app at runtime. I have been facing this problem for months but didn't able to solve it. When I tried to load the same model in Editor at runtime it work and there is no error But when I build the application in my mobile and try to load the same model then the app crashes. I am attaching logs obtained from Android studio.

 

Hi, I'm having the same issue. Did you find a workaround?

 

Hello,

at our company we are using Trilib for a large project, and we're very happy of it!

I've already sent you a support email, but it was rejected by the server.

Recently, we came across a critic issue which is related to FBX import. When we use 3DSMax FBX files, the generated hierarchy has a lot of garbage transforms like the following:



The correct hierarchy should be like this one:



Please, note that both hierarchies have been created by Trilib from 2 different FBX files. The first file came from 3DSMax, the second from Pixyz studio.
Importing those files with Unity importer, the hierarchies are both fine, but when we use Trilib, the issue happens.

I made a little research, and I found that this is related to Assimp's AI_CONFIG_IMPORT_FBX_PRESERVE_PIVOTS property, but I couldn't fix it by myself.
Attached, you can find the "broken" model.

Since our software is strictly based on meshes names, it's very important for us to get a clean hierarchy, as shown in the second screenshot. Could you please tell us how to solve this problem?


Thank you,
Francesco


EDIT: Trilib 2.0 fixed this issue

 

Hello,

a general question maybe somebody had the same problem and can help me?

I am loading multiple files async.

I need to give them some more data for each one if loading finished.
Do I need to remember or can I put it into the "onAssetLoaded" somehow?

Code (CSharp):

1.         private IEnumerator DownloadExchange(AssetDownloader aDown, string uriString, GameObject downloadGo, GameObject aggregatChild, string newName)
2.         {
3.             //this works! but I want to have more arguments...
4.             //aDown.DownloadAsset(uriString, "GLB", onAssetLoaded: onExchangeLoaded());
5.             aDown.DownloadAsset(uriString, "GLB", onAssetLoaded: onExchangeLoaded(downloadGo, aggregatChild, newName));
6.             yield return null;
7.         }
8.  
9.         //this works! but I want to have more arguments...
10.        //private void onExchangeLoaded(GameObject loadedGameObject)
11.  
12.         private void onExchangeLoaded(GameObject loadedGameObject, GameObject aggregatChild, string newName)
13.         {
14.         }
15.  

Error CS1503 Argument 3: cannot convert from 'void' to 'TriLib.ObjectLoadedHandle'

if I addd my additional arguments / parameters. Any good idea how to solve this?

Thanks a lot!

 

Solved it by adding a component with a link to the original gameobject before loading.

 

Hi is loading of lights, from fbx, supported? I am having trouble there.
Also does it not support fully fbx? There are notes on a v2 on your website but it is not on asset store

 

same thing happens to me too,
any settings for android ?

 

Support seems dead for this?!

 

i think the most chances for a responce is to write a e-mail to the developer. you find the kontact probably on his site. he works on version 2.0 i see from week to week little activity on his webseite

 

Hi.

I did not get any response from Ricardo yet. I have the problem that I need the latest version of 2.0 but the download link I had does not work since Ricardo updated his website.
Do you have a current download location for 2.0?

Thanks
D

 

The AssetStore already removed Trilib 1.x.
As his website seems to be changed I still hope this project gets continued. I'm currently heavily using this.

@rickomax Can you please give us an official statement?

EDIT:
Just read on Twitter (https://twitter.com/realrickomax/status/1315627752205287424)
"TriLib 1.9 has been deprecated on Asset Store in order to allow TriLib 2.0 approval. The new version should be online in the next few days."

 

Hi all!

I'm sorry I don't access this topic as I should.

Maintaining TriLib 1.9 is a hard and time-consuming task.
TriLib 1.9 is based on Assimp, an open-source project with daily pull-requests and code-breaking changes.

Knowing these issues and thinking about offering a better product for existing and new users, I've started to work on TriLib 2.0 two years ago and I'm proud to say it has been released on Asset Store today.

TriLib 2.0 works with a smaller subset of file formats compared to TriLib 1.9: FBX, OBJ, GLTF2, PLY, STL, and 3MF at the moment. This decision was taken to provide the highest possible compatibility with the aforementioned formats. More file formats are in the works and other formats will be implemented with more popular demand.

TriLib 2.0 is written entirely in C#, providing better compatibility with major Unity platforms.

Since the beginning I told existing users would get a free copy of TriLib 2.0 and there it is, if you're an existing user you can upgrade it for free on Asset Store.
https://assetstore.unity.com/packages/tools/modeling/trilib-2-model-loading-package-157548

Please access the Asset Store page to see an "almost full" list of features.

For anyone who strictly needs to stick to TriLib 1.9, I will offer the best support I can.
The next step for legacy TriLib 1.9 is providing access to Assimp and the code repository it uses for existing users.

I will be accessing this topic more often and probably creating a new topic for TriLib 2.0.

As always, the best way to reach me is via e-mail:
contato@ricardoreis.net

I would like to thank everyone who supported TriLib.

 

I'm trying trilib 2.0 and I'm getting an error loading the model in this file.
(Using AssetLoaderZip.LoadModelFromZipStream ())

 

Hi!

This issue was caused by bones being applied multiple times at the same mesh on the FBX parser.
I've fixed it and will include the fix on the next update.

 

Thanx!

 

I have the same issue of all my gameObjects being rotated 180° y-Axis different to Trilib 1.x.
Can I somehow rotate my meshes via assetLoaderOptions?

Best regards,
Christian

 

Hi!

You have two options:

One is enabling the AssetLoaderOptions.UseOriginalPositionRotationAndScale flag.
This will create a wrapper around the GameObject and use the original rotation Assimp loaded for the GameObject.

The other is using the AssetLoaderOptions.RotationAngles field and set the rotation manually.

If these don't work, I fear there won't be more options available for TriLib 1.9.

TriLib 2.0 load models respecting the original transform and doesn't rely on wrapper GameObjects. You can upgrade to TriLib 2.0 for free.

Hello Ricardo! All right?

I've been using Trilib since the first beta! I'm enjoying how things are working! I had a recent problem and that made me a little worried, I realized that some models are not loading the textures correctly, leaving the model with the white aspect.

I looked for the source of the problem until arriving at 3Ds Max 2020+, until the 2019 version the standard materials were "standard materials", in versions above 2020 the standard materials are "physical materials". I did two tests to show you.

Test 1: Standard Materials


Test 2: Physical Materials


Somehow Trilib does not load materials/textures when they are "Physical Materials". I wonder if there is any alternative to this problem. Will it be implemented in future updates? Is there any configuration either in the type of material or in Trilib to support?
Thank you for your help!


Pt-br:
Olá Ricardo! Tudo bem?

Estou usando a Trilib desde a primeira versão beta! Estou gostando como as coisas estão funcionando!
Tive um problema recente e que me deixou um pouco preocupado, percebi que alguns modelos não estão carregando as texturas corretamente, deixando o modelo com o aspecto branco.

Procurei a fonte do problema até chegar no 3Ds Max 2020+, até a versão 2019 os materiais padrões eram os "standard materials", nas versões acima de 2020 os materiais padrões são "physical materials". Fiz dois testes para te mostrar.

Teste 1: Standard Materials


Teste 2: Physical Materials


De alguma forma a Trilib não carrega os materiais/texturas quando são "Physical Materials". Gostaria de saber se existe alguma alternativa para esse problema. Será implementado em atualizações futuras? Existe alguma configuração tanto no tipo de material ou na Trilib para suportar?
Obrigado pela ajuda!

 

Regarding TriLib2, what Unity 2019.3 features does it use? We're interested in using it (it seems to work better than TriLib v1 based on some quick tests), but we're on 2019.2.19 and can't feasibly upgrade to 2019.3 at this point in time.

Is it possible I'd be able to get the code running on 2019.2 (obviously the sample scene files wouldn't work), or does it really require some Unity 2019.3-only features?

 

Hi!
I'm planning to downgrade it.
The only features it uses are newer C# features that earlier Unity versions don't support.
I will test it on 2019.2 today.

 

Just so you know, on Windows, I managed to get TestLibCore running on 2019.2, seemingly without issue (although models seem to load more slowly than they do with 2019.4, at least when running the game in the editor). TriLibStandaloneFileBrowser also worked, but the editor was spewing a bunch of errors about Editor plugins with the same name.

 

Hi,

finally the 2.0 is here but it completely stopped working for me. No model loads any kind of textures it is always white and there is no error why it is so anywhere.

If I try to use ZIP model+textures it always crashes with error that there is no suitable model file inside the ZIP.

Any ideas? Is there some kind of structure or naming I need to use etc.?

 

Hi!
Are you mixing TriLib 1x with TriLib 2.0?
I've seen such errors when mixing both packages, otherwise, it should work on any Unity version after 2019.3.0.
I have tested it on several Unity versions.

 

Hi!
Have you used the code from the sample scenes?
Please send me the code you're using to load the model, if possible.

 

Hi!
TriLib 2.0 handles PBR materials coming from 3DS Max and Maya. I will upload a tutorial on these in the next few days.

 

Oh, no, I'm the guy who was trying to backport it to 2019.2. There are no problems at all when I use it in 2019.4. I was just saying in that trying to backport it to 2019.2, it was complaining about duplicate plugins (one 32bit, one 64bit). Looks like the plugin import settings are pretty different in 2019.2. I ended up working around it by renaming the 32bit plugin (since we don't actually need it in our case).

 

Yep I just basically build the AssetViewer example.

 

What is your Unity version?

 

Yep, I was testing it here and it seems compatible, only the native plugins used by the StandaloneFileBrowser and GltfDraco have to been reconfigured on this version. I'll work on it till the end of the week, but if you managed to make it work by yourself, that is great.

 

2019.4.12f1 and working with URP pipeline.

 

I was testing it here and there are some issues with the UniversalRP Material Mapper, none is preventing it from assigning textures, but anyway, I will provide an update that should be ready tomorrow.

 

Is there a way to tell TriLib2 to combine meshes? TriLib1 had a CombineMeshes on AssetLoaderOptions that we were using.

Also, TriLib2 doesn't seem to work with any glTF files.

I get this error for all three that I've tried, downloaded from poly.google.com: (this was on 2019.4, and also my 2019.2 backport)
