[RELEASED] UniFBX (2) FBX Mesh Importer At Runtime

UniFBX (2)

Sometimes, we need to load 2D/3D assets at runtime in our unity application. We can do this by saving it into the Resources folder in the unity editor and they’ll be availables after compilation to load them at any time. The Asset Bundles is an option to store assets to load them from a hard disc, an sdcard or, even, a server location. However, all these options need to use unity editor and, the asset bundles case, Unity Pro Edition is required

Release: https://www.assetstore.unity3d.com/en/#!/content/61108


Demos:

UniFBX (2) Standalone Win

UniFBX (2) Standalone Mac


Features:

1. This library works with 2D/3D models imported from FBX SDK 2012, 2013, 2014, 2015, 2016.

2. ASCII importation from 3D Editors like Maya, 3DMax, Cinema4D.

3. Setting folder or URL containing FBX files

4. Setting folder or URL containing JPG, PNG, DDS, TGA format for textures (embedded textures or not)

5. Main thread or async load mode implemented.

6. Meshes importation with global scaling, normals, tangents and collider type, selectables.

7. Materials and textures importation.

8. Standard or Legacy Material.

9. Lights, cameras and TRS animation importation.

10. Web player (Depreciated), Standalone (Linux, Win and Mac), Android, iOS, WebGL supported. Unity Personal and Pro editions.

Hi carlossarria00, I tried the new version UniFBX 2 demo, it can't import texture. But I tested on old version, it can import the texture. The model generated from Recap 360. Attached file is one of the example, please help. And may I have android version for testing?

 

Hi carlossarria00, I tried the FBX with animator, but the animation and the texture doesn't import. Please help! Thanks a lot!

 

Hi HonFai

Please, downalod and try the demo again. I correct something in some script. Now, your "teadrink.fbx" model should load the texture

 

Hi carlossarria00,

Where can I download the new version? I tried the asset store demo and the above link again, and I get the same result, the texture also can't import.

 

Demos:

UniFBX (2) Standalone Win

UniFBX (2) Standalone Mac

Wait a little longer for Android demo, please

 

Hi carlossarria00,

It works great with UniFBX (2) Standalone Win. I will wait for the Android demo, it is because my project is mainly for Android and PC.

Thanks a lot!

 

Hi carlossarria00,

May I know when will the Android demo ready, it is because my project need to hand in this month on 19th.

 

hi carlossarria00
Is there anyway to import binary fbx files?

 

Hi HonFai

Here is it: UniFBX (2) Android

 

Hi Vispan

FBX files ar not supported by UniFBX (2) yet. It's a work in progress.

 

Hi carlossarria00,
It works great with UniFBX (2) Android.

 

Is it possible with UniFBX (1) ?

 

No, binary files is a work in progress for both UniFBX and stream reading as well

 

Hey, @carlossarria00 !

Your asset looks nice!
Here are few questions though:
- Does UniFBX supports huge models (and bypasses 64k vertexes limit)?
- are you working on the updates and bugfixes (some very important bugs are mentioned at the asset reviews on the UAS)?
- what is your progress with binary FBX support?

Thanks!

 

Hi Dmitriy-Yukhanov

As the meshes be either quad or triangulated a huge model will be loaded in the scene at runtime. However, take in account that it can take longer. For instance, if you load a huge fbx file about 1GB, a 32 bits operating system the application crashes. It is always recomended use files about 20MB (although a 200 MB can be loaded) for a faster operation.

Yes, this asset just can handle upto 64K vertices. Unfortunately, split meshes for more then 64K vertices is not contemplated in this asset.

 

Thanks for your reply!

 

Hi, I am looking for asset that would allow the end user to import a fbx model from a website url. I am hoping that this asset would allow me to do that but i am not getting the desired results from the windows demo everything is empty and there is no optin to add url path to the 3d fbx file.
see my screenshot and tell if this is correct or am i doing somthing wring?
Thanks

 

2 days since I posted my question and no one responded I guess that answers my question that this asset does not work and it is no longer supported.

 

Hi pakmafia

Believe me that I had not any notification about yout post. Answering your question, yes, you could add an url and download the 3D model. Really, what the asset does is parser the 3D model file and convert it in unity 3d model.

 

hi!
its really a nice asset!
but, I have some trouble when I using your asset

1) When I import my fbx file, the child object is not in the correct position, to see the picture I uploaded

2)What does the "GeometricTranslation" mean in the FBX file? and,Question 1 is related to this field? looking forward to your reply

 

Hi carlossarria00!
I tried android demo, it don't work (Status:FileNotFound). Can you help me?

 

Hi carlossarria00!

UniFBX (2) suppers mesh division for large FBX model ?

 

Ummm, what's the point of an fbx importer that doesn't support binary .fbx files? Does version 1 support binary?

 

Texture does not appear in model
It's also different from the UI you see on YouTube.

Can not I import an FBX file in binary form?

 

Hi @carlossarria00,

I've been testing the included sample scene in the latest asset store version to figure out how your importer works. I have to say that it has been quite frustrating to debug even the most basic problems, like when I had an issue with getting textures to load on the included sample models. This turned out to be a bad path string, but there's very little error checking and no console log output at all to let you know what's going wrong - I had to add my own debug logging inside your functions to figure it out. You really should add more log file output, it's quite a fundamental problem with selling a piece of code like this.

After fixing that I'm still having trouble when importing the included rabbit.FBX example file, see the attached image. The eyes and other sub-mesh models aren't loading correctly into place on the model. Presumably it's a translation or hierarchy problem? Looking at the way Unity imports the model in the editor I can see that this isn't an issue with the file (Unity correctly shows the rabbit's eyes in their sockets in the preview) - but with the runtime import. Am I missing some setting that will fix this? I've tried various options in the importer but it's taken a lot of time just to get this far.

I'll dig through the code again, as with the textures, but it would really help if you could post better information on how to use the demos (and indeed the included files in the actual asset - where your documentation is minimal to say the least...)

Thanks for any help,

Mike.

 

where may I find this?

 

Hi trdpro:

3LqpXMeXB8j8dmNXMUBzYfmbsUsF6pwFd2

 

What does that mean?

 

Well it's working in the asset store again

 

Hi carlossarria00,

I've been testing the included sample scene in the latest asset store version and had an issue with getting textures to load on the included sample models. I am not sure whether I had the wrong setting or not.

Please advice. Thanks for any help!

 

Are you sure that textures don't load?

 

Please, try to check the fbx setting as shown above

 

Just set the texture import as "YES"

 

Hi carlossarria00,

Thanks for the help. I found that I miss "file:///"in the Texture Folder, "file:///" in URL is auto omitted at running time.

 

Hi, I haven't managed to load textures so far, I get this error:

Code (CSharp):

1.  
2. NullReferenceException: Object reference not set to an instance of an object
3. UniFBXTexture2D.LoadTextures_PNG (System.String filename, System.Byte[] bytes, UnityEngine.Material material, System.String channel) (at Assets/CSUE/UniFBX/Lib/UniFBXTexture2D.cs:455)
4. UniFBXTexture2D+<IColormap2>c__Iterator4.MoveNext () (at Assets/CSUE/UniFBX/Lib/UniFBXTexture2D.cs:287)
5. UnityEngine.SetupCoroutine.InvokeMoveNext (IEnumerator enumerator, IntPtr returnValueAddress) (at C:/buildslave/unity/build/Runtime/Export/Coroutines.cs:17)
6.  

The 0 - 100% progress bar never gets to 100%, always stays between 60% - 80% as well for some reason, without giving any other error.

Spoiler: Images

I also tried with a Blinn material, same results

The app I'm working on is for Android only, if that makes any difference.

 

@carlossarria00 please, I really need to solve this, do you have any idea of what could be causing that problem?

 

I'd been exporting the models with Blender but I tried exporting with Maya and it did import the diffuse but not the rest of the textures (normal and spec), tried with another model exporting from Maya as well and now it's doing the same with the "?" images as diffuse. The first model, the one that successfully imported diffuse, only had one material, the second model has two.

 

Hi carlossarria00,

I've tried a WebGL build on a local server, but i can't load my model. It's say : "UnknownError".

 

Hello @carlossarria00,

I am using your demo project, I tried to download model from below link, but facing error 404.I am not able to download model from this link.
(https://c8d209f2f8b575dc564af150673...com/host/0B4yeGzF6xDFuc2RJeW5HZ0ZhcjQ/models/).

I even tried to download from new google drive link, but unable to download and facing error(KeyNotFoundException: The given key was not present in the dictionary).

Kindly help us to download it.

 

Hello @carlossarria00,

I'm kind of unfamiliar with Unity, licensing and the industry in general, so I was wondering:
If, as a developer, I purchased UniFBX2 and created a game using it (which may or may not be free), then built and distributed said game, how would that work with regards to intellectual property rights and all that? Are there any fees or things of the sort concerning that kind of thing?
Another small but nagging (and most likely stupid) concern: would my users also have to have UniFBX2? Probably not, but something like that would be a huge game-changer, so I have to ask, just in case.

If things turn out well for me, then thanks in advance for making such a great asset. Runtime importing of an FBX was a huge problem, and you've made my life a lot easier.
If not, thanks anyway. You've still done marvelous work here, regardless of whether I could use it or not.

 

Hello @carlossarria00,

I'm leaning towards getting this now soon, all things considered. I do have another concern however. Your Asset specifications say that it supports TRS animation. Just to be clear, does that mean I can translate, rotate and scale individual bones of a model? Or am I limited to translating/rotating/scaling the entire model as a whole?

Some help would be appreciated. Deadlines are coming up and I'm kind of panicking.

 

Hi carlossarria00,
Thanks for the great tool you developed. Here are some question and checklist I did for your references.
My issues are:
1. Somehow UniFBX could only retrieve 1 item from listMaterials, which is always diffuse. My fbx contain 3 map: Diffuse, Normal, and Specular. I had used Debug log on nearly all critical handlers, but having hard time to located the function which handling deserialize acsill file. I had attached and explained what I found during the testing.
I had uploaded those fbx and texture on my server. The path in attachment is valid. You could test it. I also screen shots all settings, and export setting used.

Here is short summary for settings applied:
fbx export:
fbx version: 2014/2015 (I also tested on 2012, the problem is same)
triangular: true
no sub object, only grouping was applied. (I also tested with no grouping)
Standard material with Diffuse, Specular, Bump map was used. All these file was uploaded on server with same folder as fbx.

2. My second issue is, the model imported has different rotation as in 3dsMax, did I miss up anything while export or runtime importing?

Most detail are stated in attachment.

Cheers,
Ignatius

 

Did you manage to solve the texture loading problem? I also facing the same issue.

 

yes,great tool ,it's work for 3ds max 2014 fbx ASCII format ,
but I want to give some suggestion here，
1：support fbx byte format,
2: if step 1 is difficult，try to use MeshSerializer reduce fbx float data to byte,
3:current version still slowly!!

 

For anyone who has texture import trouble for embedded textures, try changing line 91 of file UniFBXTextures.cs from:

Code (CSharp):

1. else if (UniFBX.list[k].Contains ("Filename: ")) {

to:

Code (CSharp):

1. else if (UniFBX.list[k].Contains ("RelativeFilename: ")) {

Took me quite some time to figure out why it wasn't working. It references the full file path, for embedded it should use the relative file path. Not sure if this creates / solves other problems.

 

if you select embedded textures,the textures will be convert to base64 string embed in fbx file,
and the path only mean nothing but a name.

 

True, something else must be going wrong. Somehow above solution works for me. I figure it won't work for all relative paths, like ones with ../ in the name.
