TriLib - Model Loading Package

Yes, that's a good idea, thanks- I'll try importing a model with only Import Materials checked like in your example and hope all the materials are included.

 

Hi!

It seems to be related to this specific model then. Have you tried out with TriLib 2.1.2?

 

I've added it to my work-list and will check it out soon.

 

Hi!
Could you try it again with TriLib 2.1.2?
If you can't load it with this version, I would suggest you sending me the model by e-mail for testing: contato@ricardoreis.net

 

Hi!
TriLib has to do a lot of stuff on the main Thread because of Unity's lack of Thread-safe methods.
That will always cause noticeable slowdowns.
I would have to rewrite TriLib from scratch to use the job system and try mitigating this issue.

 

Hi!
TriLib uses the original model orientation when loading.
There is no way to rotate it when loading yet, but I will write down this suggestion.

 

Hi!
I should really check your models to understand what is happening.
Could you please send the models you can't load to contato@ricardoreis.net?

 

Hi!
You can safely remove the Newtonsoft.Json files from your TriLib folder if you have them on your project.

 

Hi!
I'm working on this item right now and it should be included in TriLib 2.1.3

 

Hi!
Could you try loading it with TriLib 2.1.2 (latest version)?

 

Hi!
TriLib 2.1.2 exposes the AssetLoaderContext.CancellationTokenSource field that you can use to cancel your model loading. Just keep in mind that you might track your cancellation request as TriLib might not be able to cancel your loading right in time

 

Hi!
What is your target platform?
Could you send the model you're trying to load to contato@ricardoreis.net?

 

Hi!
There is no way to access this data yet, but it is something I'm going to allow, probably in the next update.
It is on my to-do list:
Public | Trello

 

Hi!
This issue has been fixed in the 2.1.2 update

 

Hi!
When the IContextualizedError.Context field is null, which means your error has been generated from a code that can't access it (probably a code on your end, but I can't be sure without checking your code)

 

Hi!
The "mesh-splitting" feature will be added in the upcoming update:
Public | Trello

 

Hi!
There is no ETA for this feature yet

 

Hi!
You would need a custom TextureMapper in order to do that.
Please refer to the "SimpleCustomAssetLoader" sample, it shows how you can implement your own TextureMapper and ExternalDataMapper

 

Hi!
Does this issue still persist in the 2.1.2 update?

 

Hi!
Could you send the model you're trying to load to contato@ricardoreis.net so I could check it out?

 

I will check out this model, adding it to my work-list

 

Hi!
I've added this feature to the 2.1.2 update.
You can use the AssetLoaderContext.CancellationTokenSource to cancel your model loading. Keep in mind you have to track the cancellation yourself as TriLib might not be able to stop the loading at the same time you request it to

 

Hi!
Actually, not.
I might drop the Dispatcher usage on a future update, but that would require a lot of refactoring

 

Hi!
Please check my answer to garrido86 above

 

Hi!
Your item is in my work-list and I'm working on it now

 

Material mappers are used to converting between native file format material properties and textures into properties and textures the scripted rendering pipeline can understand

I have some problems with this error during iOS compilation

Error

Cannot initialize a parameter of type 'id<UIDocumentPickerDelegate> _Nullable' with an lvalue of type 'const Class'

I found this post but the bug still exist
https://answers.unity.com/questions/1839645/cannot-initialize-a-parameter-of-type-id-nullable.html
Is there some fix available? Because I-m in a hurry with a release and this error was totally not expected (as all bugs, obviously)
Thanks

OK. it seems that Unity 2019.3.18 doesn't update the package manager to version 2.1.2 but it seems blocked to 2.0.11.
I moved to Unity 2020.3.17 and in this way at least I can update to Trilib 2.1.2

 

Ok. It seems solved on 2020.3.17, but the support for Unity 2019.4 it seems have some problems

 

Hi!

I will test it on this Unity version as soon as possible.
What are the problems you're getting?

 

Thanks Ricardo
the problem was specifically with iOS, see the image on my first message. It seems that StandardFileBrowser has some issue.
In Unity 2020.3.17 I didn't have this error. It works as supposed to do for all platform.

 

Hi! @rickomax

I am reading an fbx file using TriLib 2.1.1, but there are some parts that are not transparent.
Is it necessary to set it in a script or the like?
thank you

Code (CSharp):

1.         string filepath = System.IO.Path.Combine(FileDirectoryPath(), a_FileName);
2.  
3.         AssetLoaderOptions assetLoaderOptions = AssetLoader.CreateDefaultLoaderOptions();
4.  
5.         assetLoaderOptions.AlphaMaterialMode = AlphaMaterialMode.Transparent;
6.  
7.         AssetLoader.LoadModelFromFile(filepath, OnLoad, OnMaterialsLoad, OnProgress, OnError, null, assetLoaderOptions);
8.  

 

Hi All,

Has anyone tried to load multiple fbx files to unity using "LoadModelFromUri"? I need to load multiple fbx models from a server one after the other or all at once. Is there any correct way to do this without crashing Unity?

 

Since updating from 2.0.17 to. 2.1.1 and then 2.1.2 - I started to get this error in Edlitor
Assertion failed on expression: 'mipLevel < m_MipCount'
The app also crashes on Android, works only in Editor and WebGL.

What can be a reason and how to fix?

 

Hi!
Try changing your AssetLoaderOptions.AlphaMaterialMode to a suitable value. This option controls how TriLib handles transparent materials.

 

Hi!
I will work on a sample on how to do that soon.

 

Hi!
It is possible your textures do not have enough resolution to generate mipmaps.
I remember I've fixed that, but anyway, could you send me your model for testing to contato@ricardoreis.net?

 

I will check this out as soon as possible.

 

This is highly possible.
This happens on some models only.
This is an example model with this problem:

Hi @rickomax
I was able to make the original file of fbx transparent by changing the transparency mode with blender.
Thank you very much.

 

Thanks @rickomax
Looking forward to that sample.

 

Since 2.0 this package has worked super well for us!

I was wondering why animations stopped autoplaying on load in 2.0, but eventually figured out from the assetviewer sample I can add a check for animation components in my AssetDownloader component and play a clip if available.

It could be worth pointing this out in the migration post or reference materials! I assumed animations not autoplaying was an issue with my AssetLoaderOptions, because I remember autoplay being there in v1.

 

I Unity Editor I am getting this:
Assertion failed on expression: 'mipLevel < m_MipCount'

while Android Logcat reports this:

and the app crashes.

It was working on 2.0.17, but I was getting other artifacts.
Do you have an archive with older versions somewhere, so I could test and find a version, where it works with minimal artifacts?

How could I get v. 2.1.0 (before mip-map bug fix - according to changelog - I guess this fix might make the app unusable for my fbx files ) ?

 

Hey @rickomax sorry for the late reply, I sincerely appreciate your responses to my previous questions, I ended up figuring out a lot of the issues on my end.

I had another question that maybe you can help me with.
Is there a way to have more than one humanoid rig mapper in the AssetLoaderOptions? I think it would increase the chances of finding a rig if I allow it to check if "Right Starts with Left" AND "Right Ends with Left", etc.

Or maybe, can I add "Right CONTAINS Left"? If so, How can I add that?

 

This happens because texture resolutions are not power of two and you're compressing them. I'm working on a fix for it.

 

Will add this loader option!

 

Thank you.
Means I can also switch the texture compression off in Asset Loader Options to get rid of the problem temporarily?

 

I've added the "StringComparisonMode.LeftContainsRight" and "StringComparisonMode.RightContainsLeft" modes and it will be included in the upcoming update.

 

Yep. Just change your

AssetLoaderOptions.TextureCompressionQuality

to

TextureCompressionQuality.NoCompression

 

I am trying to save an AssetLoaderOptions scriptable object created at runtime to Json, but keep getting "-instanceID ...".
I am using JsonUtility, which I believe is supposed to be able to save ScriptableObjects.
Is there any way around this, besides creating my own class and writing/reading the individual values to a new AssetLoaderOptions instance?
Thanks!

EDIT: My current solution is to save the assetloader as a json string and that is a variable inside another bigger json object. Ideally, I could just have it be a variable without the second layer of Json serialization. But this may be a Unity limitation, rather than a trilib one.
