[leoboboyan]

Description of the problem

Hi, thanks for your working with 3js, i have been using it in my program.
lately, i found that the newest dev fbxloader support binary format now, that is cool !
but when i using it, it shows wrong animation, but i don't know why?
so, i come to asking for help.
thanks a lot!

Needs some help, any body ? @mrdoob
i have tried convert it to other format, with no luck.
all i found is this : https://github.com/mrdoob/three.js/issues/8511
but still , i don't know how can i fix the fbxloader

[leoboboyan]

by the way , the fbx file looks fine in other tools like assimp viewer , or autodesk fbx viewer , so i guess , it might be some transform does't apply to the skin ?
it cost me 3 days, and make me crazy, i am learning the fbx format now. :(

Seems like the zip file doesn't include texture files.

that doesn't matter, it's animation works fine on sketchfab or other viewer, but import by our fbxloader, it's really weird, why does this happen? how can we fix it ?
thanks for your reply, and sorry for my poor english.. :)

[takahirox]

FBXLoader fails to load the FBX file if the texture files don't exist. I mean, developers can't test.

I see, i will ask our modeler for the texture files and provide another fbx file seems have another problem, wish it can helps you to improve.
wait a minute, i will do it now.

[leoboboyan]

Here is the bird with it's texture files:
bird.zip

And here is another fbx file:
animation.fbx.zip
it throw error when fbxloader parseAnimations func

@takahirox

[takahirox]

About animtion.fbx.zip, it doesn't throw any errors with the latest dev.
Probably it was fixed by the recent updates.

[takahirox]

Can you share the right animation video or something?

[leoboboyan]

Sorry for so long, my disk has broken yesterday. :(
I have tried the newest dev version, and animation.fbx is working now, thanks !
And you can find the correct bird here: https://skfb.ly/68RvV @takahirox

And by the way, thank you for the specular/grossiness workflow code, it's not so important to us, but it's very important to modelers. threejs should be able to solve this problem.

And it's so pity that we delete face4, because it's useful too. @mrdoob maybe we can revert it as an option?

[leoboboyan]

And i found that there is a little problem with animation.fbx too, in threejs, there is a flash at the end of the animation, and here is how it works on sketchfab: https://skfb.ly/68Syp @takahirox

[leoboboyan]

And a new test throw an new error, file : m1911_finalFire.fbx.zip

sketch link: https://skfb.ly/68SyG

sketch use osg as lib, i have tried three days, never install success, haha..
OSG can convert the fbx format to osgjs format, I think maybe you can find out how osg deal with the fbx format, so you can fix the fbxloader ? @takahirox

Looking into this issue but fixing isn't so easy.
Can anyone help?

Looking into this issue but fixing isn't so easy.

Looking into FBXLoader.js and not seeing .transform anywhere. so it's read but never used, basically.

Can anyone help?

do you have a code that loads bird.fbx and shows the skeleton helper

@liuhongyi0101 I guess there was supposed to be an attachment, but it did not make it through the email gateway. try to drop it to the web comment form

@makc I have a PR open (#12829) that adds support for .transformLink on bones. I haven't added .transform yet, but I think the process should be similar - that is, check if there is a poseNode associated with the bone's parent, and if not apply the .transform to the parent.

Tested this since #12829 was merged and animation on bird.FBX is working correctly now. Closing.
