TriLib - Model Loading Package

Hi Ricardo,

Would it be possible to use the Uber shader with TribLib during import models at runtime?

Regards
Marko

 

Hi @Bartolomeus755, I don't have Uber Shader package.
After the next release 1.6, I'll take a look at the package and study a possible implementation.

 

Hi, thank you for reply, cant really get working animator, and didnt have chance to understand my error.
If you supply and email I can send yout the file I'm using, animations are pretty easy but I can't get to manage them into an animator.

Btw, happy new year

 

Happy new year!

Hi rickomax,

Does this update also include the async model loading, which you mentioned might make it to the next update? If not, is there any new ETA for that feature?

Regards,
Mikko Forsman

 

@layola, the 1.6 update is waiting approval on Asset Store, it has a fix that probably fixes your issue.

 

@mikko_forsman I'm studying how I could implement that.

 

Version 1.6 released!
https://assetstore.unity.com/packages/tools/modeling/trilib-unity-model-loader-package-91777

 

Hi rickomax,
Is the web build ready for 1.6?

As the animation (Legacy) has bug with AddClip, we are force to look for alternative to customize the animation or break the animation into pieces. Do you have work around suggestion?

 

Hi @Ignatius, not yet.
I'm studying the WebGL implementation.

 

What's the issue you're facing?

 

it's seem there are some bug about blank material without texture
1:3ds max have two blank materials ,without texture.,export to fbx with embed options.
2:import use trilib, and there are only one blank material .but unity editor have two material import .

 

Hi @layola, could you please send me the source .MAX and resulting .FBX for studying at contato@ricardoreis.net?

 

Hi Rick,

Originally I was facing the issue with AddClip (Basically I need to slice the animation in part), after many fail then I found out Unity had declared not to solve the Animation.AddClip problem (the new sliced animationClip can only last for 1 second. This bug was already reported.)

Then I tried to use 3dsMax to export animation clips in section with label. It work well except each new imported ClipName, the clip length are reported correct, but when apply and play through animation component, each clip's ending look like there are invincible frames was added on the last frame. For example, the perfect walk cycle loop, which the clip length is 2.15 seconds in Max, when animation["WalkLoop"].length, it also report 2.15f length (correct). When animation.CrossFade ("WalkLoop", 0.4f); the clip will not visually loop after 2.15 second. Instead it only visually loop after 20+ seconds which nearly the full length of entire fbx animation. I had implement a controller to overcome this. Basically write a simple detection to overwrite this behavior by
if ((Time.time-ClipStartPlayTime)>ClipDuration){
animation.Stop; animation.Play("WalkLoop"); }
for those clip in loop mode.

 

I wasn't aware of this bug. There are some issues when people tries to assign generic avatars to TriLib loaded objects, as the avatar definition used on animation clips must be the same as the loaded object. So I'm creating a TriLib menu command for the next update, that generates an AnimationController from an existing mesh, using TriLib. Then the user will be able to use this AnimationController when loading generic avatars with the same bone naming as the original.

 

Hi @rickomax,

Currently working on hololens project for school and we bought your amazing asset loader but currently running into some issues. Everything in the unity editor works fine the test spider loads and stuff. But when we build it for the hololens it shows a parsing file error.

Code (CSharp):

1. Exception: Error parsing file.
2.    at TriLib.AssetLoader.LoadFromMemory(Byte[] fileBytes, String filename, AssetLoaderOptions options, GameObject wrapperGameObject)
3.    at TriLib.Samples.ModelDownloader.<DownloadModel>d__8.MoveNext()
4.    at UnityEngine.SetupCoroutine.InvokeMoveNext(IEnumerator enumerator, IntPtr returnValueAddress)
5.    at UnityEngine.SetupCoroutine.$Invoke1(Int64 instance, Int64* args)
6.    at UnityEngine.Internal.$MethodUtility.InvokeMethod(Int64 instance, Int64* args, IntPtr method)
7. (Filename: <Unknown> Line: 0)

Any ideas about this we are kinda stuck right now

 

@endargon, what's your device specs?

(Only the Sample 1 was adapted for UWP until this moment)

 

@rickomax,

Uh well it's a hololens so I guess https://developer.microsoft.com/en-us/windows/mixed-reality/hololens_hardware_details are the specs.

 

I could not test TriLib with Hololens (as I don't have one), but the x64 UWP app runs just fine.
So I must know what's the device architecture (x86, x64 or ARM) in order to investigate the issue.

 

ah @rickomax the architecture is x86

 

@endargon

I've sent you an updated package link via private message, please tell me if it works.

Do you have Skype?
If yes, please send me via PM or e-mail: ricardo@ricardoreis.net

I'm working on UWP 32 bits issues, and you could help me testing the builds (as I don't have the Hololens device).

 

@rickomax Hmm after recreating my entire UWP folder and quadruple checking my dll options are correct.
It suddenly started working


Going to try with some more complex models in a bit but ay I can safely say it works on the hololens emulator which means it should also work on the real device.

 

@endargon

There's a TriLib update waiting for approval where I can load models from memory on UWP:

 

Hi!
I'm trying to load an FBX model that have multiple materials assign for different parts/meshes but just one material is loaded for it all. If the materials are different they all load nice but if they have the same settings only one is loaded. I need to load they all even if the are the same since i need to read some name convention and make some changes at each one after load the model.

Any sample how to load the FBX with all materials correctly assigned even if they have the same settings ?
Bye!

 

@CogumeloSoft,
please send the model to: contato@ricardoreis.net
I must check your file to figure-out a solution.

 

Done
Hope you guys can help us.
Bye!

 

Hello Rickomax.
I'm trying to import Humanoid animation from fbx.
"UseLegacyAnimations = true" works fine, but turn off the flag cause empty AnimatorController.

What should i do?

 

Hi @Cretaka.
We are working on a system to generate generic animation controllers on Unity editor, from models loaded with TriLib.
When working with generic animations, you need an existing animation controller, and in this case, we can't use an animation controller created with clips loaded in Unity editor, as TriLib objects and Unity loaded objects hierarchies are different. The best way to work with generic animations at the moment, is using legacy animations. If you are working with humanoid animations, you can modify the code at "AvatarLoader.cs".

 

Hi Rickomax
Thank you for your quick reply.
There is several characters in Unity scene, they have same bone hierarchy, but proportion is different.
I want to load animation with TriLib at runtime, and attach to them.
I should challenge with legacy animation. Well.

Regards

 

Hello!
We recently bought the plugin for our project. We experience problems with some models.
For example this model from the asset store (it's free and we used it for testing) is loaded with wrong positioning.
http://u3d.as/mK7

By the way the plugin is great! Good job! Hope all minor issues will be fix soon )
Thanks in advance.
Best regards, Alexander.

 

Hi. Thank you for your purchase!
We have some FBX transform issues with certain models, as listed in our known-issues list.
We are working to fix these issues.

 

@rickomax Hi rick, I too will be really excited to see async loading feature with your asset. Thank you

 

Hey. It's planned for a future release.
I'm focused on fixing iOS issues at the moment, after that, I still have some bugs to fix.

 

Hi.

I've been receiving many e-mails about TriLib iOS issues.
I've been replying these users and warning them I have only one Mac
computer avaliable to work on TriLib, and this computer is under maintanance.
I could have a second machine, but that's not my reality as an indie developer.
I guarantee all iOS issues will be fixed as soon as possible, it's just a matter of time.

Best regards,
Ricardo Reis.

 

Hello again rickomax,

I've noticed that *.stp and *.step files are currently not supported by trilib, but they are supported by assimp (at least according to https://github.com/assimp/assimp). Is support for those formats coming at some point?

Best regards,
Mikko Forsman

 

@mikko_forsman File formats support list is quite outdated for Assimp, I'll have to check the list myself. Have you made any test with .stp or .step files?

 

Hi,

I just quickly tested with some .stp files, and got an error "Exception: Error loading asset. Assimp returns: [IFC: Unrecognized file schema: CONFIG_CONTROL_DESIGN]". So I guess that means that Assimp doesn't actually support stp files?

-Mikko

 

Possibly, I'll report this to the Assimp team.

 

Quick update: a patch with iOS fixes is awaiting for approval on Asset Store.

 

Hi. I've just updated TriLib to version 1.6.5.
This version fixes current iOS issues.
Keep in mind that at least an iPhone 5s or an iPad Air with iOS version 11.2 is needed in order to load TriLib libraries.

Best regards,
Ricardo Reis.

 

Hi,

I tested your plugin with a obj file and i've this error. (attachments)

Thanks.

 

@julienranchoux what's the file extension you're trying to load?

 

@rickomax "file.obj" i sent you a bug repport from your website two weeks ago

 

Oh, thank you. I'm having some delay on bug fixing lately, as the co-developer that works with me is kinda busy.
I'll keep you updated.

 

@rickomax

I'm experiencing the issue reported by @hugopok earlier in this thread. I'm using Unity 2018.1.0b8 (linux) and am importing a project created by someone else that includes TriLib,

A dialog appears when importing the project. Choosing "Ask to Save Changes and Restart" loop reloads unity showing the same dialog.

TriLib was unable to find the native plugins.

If you just imported the package, you will have to restart Unity editor.

If you click "Ask to save changes and restart", you will be prompted to save your changes (if there is any) then Unity editor will restart.

Otherwise, you will have to save your changes and restart Unity editor manually.

[Ask to Save Changes and Restart] [I will do it Manually]

 

You can press "No" on this dialog, then please check if "TriLib/TriLib/Plugins/x86/libassimp.so" and "TriLib/TriLib/Plugins/x86_64/libassimp.so" are enabled to be deployed on Linux.

 

Selecting either file in the editor shows a "Platform Settings" pane at the right,

TriLib/TriLib/Plugins/x86/libassimp.so

* [x] Linux, x86
* [ ] Linux, x86_64

TriLib/TriLib/Plugins/x86_64/libassimp.so

* [ ] Linux, x86
* [x] Linux, x86_64

 

Ok. that's the way it should be.
Please, just click "No" when the dialog appears and tell me if it works.

 

@rickomax

I tried to load a known fbx file in the source of my project using the official example, but an error occurred with this message in the unity console

Unable to load mymodel.fbx. The loader returned: System.Exception: Error parsing file: Assets/Sample/Samba Dancing.fbx ---> System.DllNotFoundException: libassimp

From within the editor, the menu item "TriLib > Configure Avatar Loader Sample" is grayed out and disabled
