Modo 12 to Blender, import error. #16
Comments

Confirmed. It happens when you import when not in object mode. We can just switch to object mode before we create the armature. Possible patch diff --git a/addons/io_scene_gltf/node.py b/addons/io_scene_gltf/node.py

Yup,switching to object before importing works, thank you!! |

this issue

* Use empties instead of an armature for glTF nodes
This removes support for skinning.
* configure the camera from the gltf data
* camera/create_camera: intentionally return an uninitialized camera for an unexpected type
* camera/create_camera: handle a missing zfar in the perspective data
* camera/create_camera: fallback behavior to handle a missing apesctRatio
* create_camera: the glTF yfov must clearly go to the property `angle_y`
of the Blender camera, while the `aspectRatio`, if present, affects
the resolution instead of the `angle_x` (since the latter is computed
from the `angle_y` and the resolution in Blender)
* removed auto smoothing
* Tidy up __init__ and unify the caches...
...using just one cache-lookup function instead of one for every
different type of object.
* Tidy up the mesh creator and enable RGBA colors
RGBA vertex colors are supported (required) by Blender 2.79 it
appears.
* Begin implementing a new node creator
Based on creating first a virtual forest that mirrors the scene
graph we're about to create in Blender. Details to be documented
later... if it works out :)
* Creates skins and attach them to armatures
Skinning is now working (again (again))...
* WIP animation loading
Messy and VERY slow for the moment, but functional so I'm commiting
it for my own reference.
* Put animation handling in order
Comments explained the main reasoning behind the bone function.
Also switching from keyframe_points.insert to the add/co loop
gave a **huge** performance boost.
* Use memoryviews for buffers and buffer views.
This is for faster slicing.
This doesn't make any apparent impact on import times but hopefully
it saves some memory ^^;
* Cleanup and explain how the vforest works
* Note that Blender 2.79 is needed
...because 4-component vertex colors are assumed.
Should we use some shims to papers over the Blender version
differences and get greater support? I don't have access to !=2.79
vresion atm though so it doesn't matter for now.
* Minor tweaks
* Put cameras in the scene
They don't point the right way or anything but they're there :)
* Handle creating scenes again
But have an option to just put everything into the current scene
too (I like that better).
* Add more import options
* Cache images used for texturing
This prevents loading the same one multiple times.
* Autogenerate node group data
Using the groups from the exporter, thus relieving us form writing
all our own node groups.
The group for Specular Glossiness is also part of the serialized
data, so supporting that is getting closer.
* Small work-around to enable vertex color influence
We add superfluous COLOR_0 layers to any mesh that uses a material
that is ever applied to a primitive that has a COLOR_0 attribute.
This let's us add an Attribute node to those materials without the
problem of solid red colors coming in.
COLOR_1, etc. are still not supported (well, they're imported of
course, they just don't influence the materials).
* Tighten up scene graph creation
- Avoid creating dummy vnodes for meshes when possible.
- Rotate cameras to their (correct?) position
- Some slightly tighter docs.
- Some more robustness in realizing vnodes; it would probably be
possible to use an armature for the whole forest again with minimal
code changes
* Fix some typos in animation.py
Animating non-bone locations should work now. Curve clean-up should
be working too.
* Avoid bone->nonbone->bone child relations
The vtree beneath an armature should now be all bones except
possibly at the leaves, and we should realize them correctly(?)
now.
Also fix a typo with mesh names.
* Rename node.py -> scene.py
Avoids confusion with the similarly named node_groups stuff.
* Large push towards full material implementation
Support for pbrSpecularGlossiness was added here too.
* Fill in sampler properties
Such as they are, anyway.
* Support KHR_materials_unlit extension
* Gate animation importing behind a flag...
...since it's still weird. Make the options prettier and ignore
scenes by default too.
* Allow for >4 vertex weights
...by using multiple attributes sets. We anticipate here, since
though there is a PR for this, it hasn't been merged into the spec
yet.
* Bugfix: do not modify vertex color accessor arrays
If the accessor was used again later in the glTF, we would have
seen a modified array since we hard-modified the accessor elements.
Avoid doing this.
* Bugfix: don't set vertex weights of 0.0
If the joints were eg. [0,0,0,0] and the weights were [1,0,0,0],
previously we would overwrite the weight for 0 three times so it
ended up as 0. Now it will correctly be 1.
* Support MSFT_texture_dds extension.
We hardly have to do anything since Blender will already handle DDS
textures so we might as well. Untested though.
* Implement KHR_texture_transform
Untested.
* Greatly simplify animation importing
I initially thought the pose TRS was computed from (final TRS) *
(rest TRS)^{-1} (ie. the opposite order of multiplication from what
I now believe is correct.) Under this scheme, the pose components
could depend on multiple final components, which required bringing
the curves under a common domain. But under the correct order of
multiplication each pose components depends only on its corresponding
final component (and the rest TRS) so that turns out to have been
over-complicated and, thank God, we can finally get rid of it!
Though, alas! it does not fix Monster.
* Add COLOR_X, etc. layers in order of X
This ensures that COLOR_0 is always the first (and ensures Blender
thinks its the default, for eg. TEXCOORD_0 and UV maps?) and avoids
any gaps in the sequence of X.
* Slightly better bones
- Pick better bone lengths (when the bones are rotated the armature
actually looks plausible now)
- Report a warning when bones had non-unit scalings in the glTF
* Only add vertices referenced by the indices (#29)
* Work-around re vertex colors for Blender 2.79.0
* Set animation curve interpolation
Also fix a typo that mysteriously did not prevent Blender from
figuring out what the fcurves were targeting.
* Allow the user to rotate bones
For example, try rotating the bones in CesiumMan or Monster by 90d
in the X direction to get the skeleton to look correct.
I am somewhat uncertain of the math for this.
* Rotate the short way for linear interpolation
See KhronosGroup/glTF/issues/1395. Observe the difference in
AnimatedTriangle or the low-poly fox.
* Be noiser when we put a node in the wrong place
Just so the user knows. Very minor, theoreteical fix for bone
lengths too.
* Polish armature/bone creation pass
The restriction about overlapping armatures is lifted and we no
longer require a skeleton property.
* Add groups to animations
This makes it more like what you'd by adding keyframes by hitting I
* Fix action creation
Fix a typo that created superfluous actions.
Always make the first animation the one that plays by default.
Fix setting of the default action on armatures.
Don't let Blender delete unused actions.
* Fix regression of #16

I'm saving the .glb file from Modo 12 and trying to get a simple cube into Blender 2.79.1. Upon importing I get the following errors(see attachment) ,the cube.glb is also attached in the zip.
