A bunch of joints, animated, cannot be converted
I basically have bunch of joints, animated, under Armature, exported from Blender.

gltf2usd fails if a texture tries to copy onto itself in the same directory
Add logic to not overwrite a texture in the same directory if it is the same: #63
Latest converter update is confusing and has weird issues...
I'm wondering what's the best way to install the Python module. In the past, I simply copy paste all the files in the source into the folder where the gltf asset is, and then run the Python tool:
But in the latest update the tools have grown and when I tested a conversion using the tests asset, I keep getting weird error:

shutil.Error: `Boss_diffuse.png` and `/Users/jimmyg/Documents/PROJECT20180922/Madain_Saleh/anim3/tests/assets/Start_Walking/Boss_diffuse.png` are the same file
UPDATE: Regarding me being dumb copy pasting the script into the folder, I just realized I can keep the original Tool, then open terminal inside the source tool folder and then drag and drop the GLTF file to be converted and then simply just output the result inside any folder. I am still getting familiar with commands and terminal.
For example:
unsupported animation target path weights
raise Exception('Unsupported animation target path! {}'.format(target_path))
Exception: Unsupported animation target path! weights
You can download this model from here. buster_drone glTF autoconverted format
To get this animation to build I removed the paths referring to weights in the glTF ascii file. However, the usda animation is distorted.
Is animated "stepped" frames / GIF / PNG possible in GLTF to USDZ?
Like the subject, I am actually thinking to do some kind of stop motion animation using bunch of PNG + transparency. And having this as GLTF would be quite fun, I think.
Although so far, trying to do this using 3D mesh sequence seems like not possible since kefyraming visibility in block (not linear) or stepped keys do not translate to GLTF... unless I am doing it wrong? Wondering if Scaling On and Off in stepped keys would work ...

UnicodeEncodeError: 'ascii' codec can't encode characters in position 0-11: ordinal not in range(128)mesh under the root mesh needs to be scaled to (1,1,1) for scaling to be correct
@kcoley I've also picked up that when you have a mesh under the root mesh hierarchy, if it doesn't have a 1,1,1 scale its won't correctly scale relative to the root mesh. To fix this I scale the root to (1,1,1) and all my nested meshes to a (1,1,1) as a workaround. Usually a pain in the but if you forget to do it much pain later!
BTW, the GLTF input file is scaled correctly in the sandbox, so it seems like the usdz conversion is not handling the scaling correctly from GLTF.
Bug in some animation models
Some models do not export and animate as expected.
Here are two samples:

Failed at boost installation
I keep getting some compiling error when I first ran the USD installation script. I think it has something to do with python and boost.
I have first got a boost installation error that say that there is an error running the below code
./b2 --prefix="/usr/local/USD" --build-dir="/usr/local/USD/build" -j2 address-model=64 link=shared runtime-link=shared threading=multi variant=release --with-atomic --with-date_time --with-filesystem --with-program_options --with-regex --with-system --with-thread --with-python install
then I ran it and I logged the results below, any ideas where this is coming from?

Animating on MacOS but not on iOS, maybe still "Armature/" related
I thought this one was already solved and I tried deleting all "Armature/" manually using USDA, but somewhat the USDZ is not working. Strange...
Example animation: (made using Blender Grease Pencil, exported as GLTF)

Add scale option for generating usda files
By default, generated USD files are scaled by 100x to convert from glTF's meters to USD's centimeters. However, not all models are properly scaled. Add an option to specify the scale to use during conversion
Animating more than 1 character is not working
I have two character animations I posted at fusionar.app
For some reason the two characters don't play nicely as one scene file in usd or usdz. They work as dae files in both Cheetah3D and Blender. I've attached the glTF 2.0 files I was using for the conversion. The characters are animating ok in the sandbox glTF viewer.
two_Characters.zip
I spent several hours on this today manually editing the usda file to see if I could find a hack... but lucked out!
I haven't even seen an example of a usdz animating more than 1 character... so I'm in unchartered waters!
quaternion rotations are ignored on iOS/XCode
Since iOS and XCode currently do not support quaternion xform rotations, add an option to convert quaternion rotations to baked linear Euler rotations:
alpha values should be removed for iOS/XCode if not used in the glTF file
Scale wrong - when using keyframes in GLTF file
@kcoley I'm currently chasing another bug relating to scaling after adding keyframes to the GLTF. What you may not have picked up on the cubeBounce example I posted yesterday. The floor scale was not correct relative to the 3 cubes for the usdz version (that was because it was not key-framed).
So in a nutshell, whenever you keyframe a mesh, that key-framed mesh changes its scale, and it is not correct. The attached files is the same file, 1 without keyframing - the scale is correct. 2 with key framing the scale is wrong.
If we can fix this issue, we might finally solve the issue with multiple animations getting out of whack.

gltf2usd does not handle base64 texture strings
- Add support for base64 texture strings
Add direct usdz export support
- Add an option for directly generating usdz files instead of generating USD/USDA/USDC first
Modularization/Organization
This is my first large-ish Python project that I've had to poke around, maintain, and extend. I was wondering what kind of strategies we can consider to split up the code a bit (gltf2usd.py is creeping up to 2k LoC). My goal would be to make it easier to keep track of control flow and to make it easy to find related and connected code blocks ("I want to fix an animation bug in joints. This module looks like it handles that.").
I'm leaning toward splitting parts of the GLTF2USD class into:
Textures(gltf_loader, usd_node)Meshes(gltf_loader, usd_node)Animation(gltf_loader, usd_node)
I would love to have them be "pure" functions but the Python USD kit seems to be written in a procedural style.
edit: I just noticed @kcoley's work in the refactorSkeletons branch. It seems to be cleaner
issue with iphone X
@kcoley Both my most recent usdz files posted on www.fusionar.app with rotating cubes using he latest version and --use-euler-rotation handle - Are working ok with iphone 7, ipad mini & ipad pro... in iOS... but are throwing an error when viewing with iphone X. I have not had a chance to check any other iOS devices yet. I have checked the problem on two different iphone X and it never previews so it seems like an issue of some kind.
skeleton animations do not play on iOS
- Make modifications to get skeleton animations to play on iOS
Weird Bones Naming causing errors
From Blender default, bones often named: bone.000, bone.001, bone.002 and this GLTF to USDA converter seems to dislike this idea.
Perhaps there should be a checker that can modify bone.000 to bone_000? Thanks
👍
Support non ascii characters in texture file names
Hi
I am having a gltf file with swedish UTF-8 texture file names like LÖVÅS and so on.
The utility throws a UnicodeEncodeError: 'ascii' codec can't encode character u'\xd6' in position 19: ordinal not in range(128)
We could either support it or detect these characters and replace them with latin ones.
Here is the full error log.

A simple turn table animation does not work
I am animating an object in Z-axis from 0 to 360 ° with 2 linear keyframe in Blender for 100 frames, exporting as GLTF, and I am not getting animation somewhat. Quite strange.
If I made keyframe so that the animation goes from 0 to 355 ° it seems to work (as GLTF, using online GLTF viewer) but very slow, and seems to be trimmed and --fps does not make any different.
The resulting USDZ does not spin either... :(

I am using a different MacBookPro, running this Python tool to convert GLTF to USD. Trying to convert:

However, keep getting the error above.
I have not installed XCode 10 or MacOS Mojave on this new MacBookPro.
Model ends up without texture
I'm trying to get a GLTF converted in USDZ but somehow, my model ends up without any texture. When I uncompress the .usdz the texture file is in there.
For some context, I installed last week USD by Pixar and gltf2usd on a Debian on AWS EC2. It worked, I was able to export and get a nice looking USDZ.
Then I proceed to do the same again but on an Amazon Linux 2 on AWS EC2 and after some first tests, I see the USDZ doesn't display its texture. I taught it was because of some library compatibility or such kind of problem so I keep digging but now when I resolve myself to go back to use Debian I try again to convert the same GLTF and I get the same without texture model.
I wonder if this could come grom gltf2usd? Is there something obvious I'm missing here?
Crash due to node name starting with number
Hi
I noticed that if the node xform names start with a number the exporter crashes inside usd with an illformed sdfPath.
Warning: in _InitWithString at line 106 of c:\users\d_chr\downloads\usd-master\pxr\usd\lib\sdf\path.cpp -- Ill-formed SdfPath </root/00095036_LACK_N_cff_tbl_90x55_white001_1_0>: syntax error
This is the section in the gltf file,notice the name of each xform.
"nodes":[{"mesh":0,"translation":[-0.00169372559,0.0,0.00169372559],"rotation":[0.0,0.0,0.0,-1.0],"scale":[1.0,1.0,1.0],"name":"00095036-LACK_N_cff_tbl_90x55_white001:1"},{"mesh":1,"translation":[-0.00169372559,0.0,0.00169372559],"rotation":[0.0,0.0,0.0,-1.0],"scale":[1.0,1.0,1.0],"name":"00095036-LACK_N_cff_tbl_90x55_white001:2"},{"mesh":2,"translation":[-0.00169372559,0.0,0.00169372559],"rotation":[0.0,0.0,0.0,-1.0],"scale":[1.0,1.0,1.0],"name":"00095036-LACK_N_cff_tbl_90x55_white001:3"}]
The error manifests in gltf2usd.py in line 95. in _convert_node_to_xform
xformPrim = UsdGeom.Xform.Define(self.stage, '{0}/{1}'.format(usd_xform.GetPath(), GLTF2USDUtils.convert_to_usd_friendly_node_name(node.get_name())))
Just by changing the xform name with starting a letter no error is thrown. This must be a limitation of the usd sdk it can not process xform node names that start with a number. For example this passes. note the character before the name.

scaling different when using keyframes
@kcoley There is an issue with scaling when you add keyframes to the GLTF file. The GLTF looks fine, but the conversion to usdz is out of whack. Sticking with the same sample cubeBounce. I have pair again, one with no keyframing at all. The other with a keyframe on each separate mesh. Its a flat hierachy, but it makes no difference issue still happens either way. I suspect the scaling is not applied consistently when the gltf file contains keyframes.
I removed all the timeSamples with scale set to 0.01.
float3 xformOp:scale:scale.timeSamples = {
0: (0.01, 0.01, 0.01),

Multiple transform keyframe animations not working anymore
@kcoley I started using your new version since yesterday. It seems that multiple transform keyframe animations are not working in this new version. I have not looked into why just yet. But multiple keyframe transforms were definitely working in the previous version I have working examples which help me verified the issue. If you need a test file, let me know?
Error when no BaseColorTexture and only BaseColorFactor
Hi
i have gltf models which have only a baseColorFactor and no baseColorTexture in the pbrMettalucRoughness material. When processing i get this error. I tested it and its because there is no texture. it gets the color somehow in the wrong format.
This fails
"materials": [

"baseColorFactor":[0,0,0,1.0],
"metallicFactor": 0.0
},
"emissiveFactor": [
0.0,
0.0,
0.0
],
"name": "blinn3-fx"
}
],
This succeeds using the same mode just changing the material definition

Support for Apple's package stand-alone USD (v18.09) libs
Kacey,
Currently you will need to initially have USD v18.09 installed on your system and have the Python modules built Pillow (Python module for image manipulation)
Would gltf2usd build with Apples new package python-usd-library ?
In the python-usd-library readme file it stated the following
This binary library was compiled using version 18.09 of [the public USD Github repository](http://openusd.org) with the following build script arguments (see USDPython/README.md for further details):
python USD/build_scripts/build_usd.py --build-args TBB,extra_inc=big_iron.inc --python --no-imaging --docs --no-usdview --build-monolithic USDPython
Issue converting GLFT and getting texture to properly render
I've been playing around with this and have been having an easy time converting GLFT's from around the web... but have been having a lot of problem getting ARKIT to properly render out the textures from assets of my own. I was wondering if there was some insight that could be provided as to why my USDZ version is not working when the GLFT is fine.
I incidentally had to fix something locally to get this to convert (I havent sent a pull request for it yet) The first line of _convert_texture_to_usd seems to have indexing problems when referencing the textures... ive fixed this by having it use the actual source:
image_name = gltf_texture if (isinstance(gltf_texture, basestring)) else self.images[self.textures[gltf_texture['index']]['source']]

Index out of range errors
I've notice a number of times I've got index out of range errors.
in the most recent case it occurred inside of def _store_joint_animations
I add the following exception handling. I think it was happening because the models had several bone branches (rather complex bone animation).
Anyway I modified the following code which at least enabled the usda file to build. The usda animation still won't run! But the usda file itself at least builds with the correct mesh & materials.
try:
scale[0] = skeleton_joint.GetRestTransformsAttr().Get()[joint_index].GetRow3(0).GetLength()
scale[1] = skeleton_joint.GetRestTransformsAttr().Get()[joint_index].GetRow3(1).GetLength()
scale[2] = skeleton_joint.GetRestTransformsAttr().Get()[joint_index].GetRow3(2).GetLength()
except IndexError:
return
I'm guessing the command tool will need a bit more error handling for it to function more smoothly with the large variations or cases it would encounter.

Previous tentacle animation does not work anymore after the updates
Not sure what's going on... but seems like there GLTF2USD converter has made changes in hiearchy, where I used to just delete "Armature/" and animation works on both MacOS and iOS.
Today when I tried again, the animation works on MacOS, but not on iOS 😞
This is USDA I kept from the past, works for both MacOS and iOS:
This is USDA being produced by latest update:
Hierachy is now different, and I could not just delete "/Armature" ...
Strange Rendering Issue
I am having trouble figuring out why this USDZ file (I used gltf2usd to make a USDA, then zip'd with usdzip) is rendering incorrectly. Using usdview I'm getting a fully black model, and when I try to open it with iOS 12 Beta 9, the model is tiny and invisible. I've combed through the Materials and they seem fine, as do the Meshes. I'm fairly new to USD so I'm not sure where else to look. Is there a better way to check the model's textures?
Here is the original gltf:
carrothead.gltf.zip.txt
And here is the generated USD file:
carrothead.usdz.txt
Working with both COLLADA2GLTF & FBX2glTF
Given this is a command line tool, it makes sense for it to work well with other 3D filetype command line tools.
These command line tools convert DAE & FBX -> GLTF 2.0
COLLADA2GLTF & FBX2GLTF
This tool can then convert the GLTF 2.0 -> USD & USDZ.
If you can get this tool to do that flawlessly, that would be a powerful tool! I think that is a really good goal to go for. What do you guys think?
It would be nice to document the known issues with each of these tool using standard models, as a way to iron out all the issues.
Material not rendering with some Animations models
Has anyone else successfully assigned materials or solid colors to multiple faces incorporating animations?
So you might have a single mesh broken into mulitple faces, like animating a dinosaur, separate material assignment for say the eyes, body & claws. So 3 separate png files will be in the usdz archive each assigned to 3 different faces.
I have successfully created several animations incorporating animations with only 1 material assignment for single mesh. All my posted bone animations on fusionar gallery were built with only one material assignment for a single mesh.
Note: For models that don't have any animations material assignment is working fine. It only seems to happen with models that incorporate animation.
I had a look at the usda file.... it seems to have
