Reproduce:

I made a small gist here that you can run on node.js to reproduce the problem: https://gist.github.com/bnjm/9ab98822642337346b5d77b70786b6d0

But you can also reproduce with this snippet:

io3d.storage
  .exportDae(
    '/535e624259ee6b0200000484/2017-11-23_21-53_p1lBYj/2017-11-23_21-53-53_pP2nc8.gz.data3d.buffer',
  )
  .then(io3d.utils.processing.whenDone)
  .then(console.log)

Result:

Exported .dae file cannot be opened by xcode or blender. Outputted collada file is here: https://gist.github.com/bnjm/571438f577ed6f2e1f8c0eaf7560fdd6

Additional info:

• textures are loaded correctly
• obj export works correctly for the same piece

We think there are other furniture pieces affected and will these to the gist after some more testing

Importing the attached data3d.json file with or without the texture folder results in the following error:

Surrounding.zip

The file has been exported with the data3d addon from blender interface

We need documentation for 3d artists

• installation
• features and options
• use from command line

And documentation for the code for contributors

• design and structure of the add-on
• documentation of code

Reproduce:

export the following chairs which both have different color materials
https://furniture.3d.io/#furnitureId=51734d5c-9b44-4e05-8991-2534a8707511
https://furniture.3d.io/#furnitureId=91a18c8a-f414-4aed-8a8f-b1c71549e214

io3d.furniture
  .get('51734d5c-9b44-4e05-8991-2534a8707511')
  .then(x => x.info.data3dStorageId)
  .then(io3d.storage.exportDae)
  .then(io3d.utils.processing.whenDone)
  .then(x => console.log('should be black': x))

io3d.furniture
  .get('91a18c8a-f414-4aed-8a8f-b1c71549e214')
  .then(x => x.info.data3dStorageId)
  .then(io3d.storage.exportDae)
  .then(io3d.utils.processing.whenDone)
  .then(x => console.log('should be red:', x)

Result:

Both are grey

There were some lightmap bake tasks that had pink color bleeding from (possibly) missing textures.

Verify that loading placeholder images work as intended.

References commit 4156d11

reproduce:

1. export the yellow couch as data3d buffer from https://spaces.archilogic.com/model/archilogic/ezl15mqb?modelResourceId=f7a3e584-374a-4647-93ba-aa0bd56574df&mode=edit&view-menu=none&main-menu=save&logo=false
2. import data3d buffer in blender using import plugin

result:

normals look distorted.

note:

the gray couch is a copy of the yellow one where textures have been deleted. importing only the gray couch into blender will result in normals looking correct:

files for convenience:
gray_couch.zip
yellow_couch.zip

The furniture piece Tabano (productResourceId: 0b35a7a1-1251-4652-bfdb-62375558db99) displays ok in archilogic and a-frame, but when exported is at the wrong scale

Steps to reproduce:

io3d.furniture
  .get('0b35a7a1-1251-4652-bfdb-62375558db99')
  .then(x => x.info.data3dStorageId)
  .then(io3d.storage.exportDae)
  .then(io3d.utils.processing.whenDone)
  .then(console.log)
// 535e624259ee6b0200000484/processing/2017-11-28_17-34-19_OBcHg4/2017-11-23_22-27-15_HVGQBc.zip
// => open file in 3d editor

The result is the same with io3d.storage.exportObj leading to it being an issue with the importer.

Here's the buffer file:

Data3d IO will be an open source addon

• Wiki pages with documentation & usage (checkout PYdocs for automated documentation)
• Wiki design&workflow // version number
• Remove redundant code
• Create Issues for known bugs and missing features

Open issues - ** transfered from https://github.com/archilogic-com/services/issues/41**

WIP

Import

• Clean Mesh & use_image_search optional @(low priority)@
• Do we have object-specific metadata (-> check with tomas about visibility attribute)?
• clean mesh / clean hierarchy > improve performance (because of bpy.ops use)
• Meshes with no uvs that are merged with meshes with uvs: handle unwrapping / disable merge / mark faces (now we generate additional, faulty uv data because of auto uvs when merging)
• Option to disable coords distinct, remove doubles, tris to quads for previews
• Reset logger config / remove global variables from addon (eg. the reference to the buffered file)
• Improve buffer import performance (parsing data is much slower then json parsing -> data3d importer issue
• convert_tris_to_quads breaks normals

Export

• if UV channel does not conform the name, take the channel by index (0 -> uvMap, 1-> uvLightmap else no UV)
• Material Texture Scale for 3d artists
• export hierarchy instead of flattened @(low priority)@ (only for data3d.json)
• Apply world matrix from operator params or remove
• export = import = client (sustainability)
• Don't export uv's if uv area is 0
• texture references to texture directory!

General

• Implement material-cycles / cycles-blender converter service for 3d artists (with restrictions, and only for 3d artists) @(low priority)@
• Implement toggle cycles-blender render- done
• Implement a convert to cycles method for 3d artists

This plugin can be used without launching the Blender GUI straight from the command line.
That's useful for automated or otherwise scripted workflows.

There's no documentation for that yet, so let's change that 💯

• Create deployment for blender addon
• Change addon name reference in spaces
• Remove addon from spaces repository

original file: capsule.obj
data3d file: capsule.data3d.buffer

the convert_tris_to_quads functionality in the data3d importer causes this problem

Add test to export_image_textures (line 76 in io_scene_data3d\export_data3d.py),
warn the user about the missing files and continue.

location: <unknown location>:-1

the UV faces on the left are wrong, they are dragged across the whole texture

imported data3d file, blender scene with result

by process of elimination we assume the problem happens in the importer

Note:
This problem occurs when downloading baked archilogic scenes and importing them with the addon. We did not see the problem not happen with the first UV channel, only with the second channel (lightmapUvs)
A lead to find the source of this is to determine what is the difference between these two channels.

1. Import the attached data3d buffer file in blender:
   xyz.data3d.buffer.zip
2. Check position coordinate values of all objects. They should be the same as in the data3d buffer file:
   

Notes:

• Decoded data3d buffer: https://editor.archilogic.com/3d/template/new?file=/archilogic/tp_test/xyz.data3d.buffer&mode=sdk

Right now the getting started documentation is lacking proper documentation on:

• What this plugin allows you to do with it
• How that works

You can use the headlines to fill in missing information, but basically:

• Importing a model
• Exporting a model
• Toggling the engine

If you want to work on this but aren't sure how to get going, comment here and mention me or @Aadjou for details 👍

Use Case:
A user downloads an Archilogic model as a blend file and wants to manipulate the materials in cycles.
When exporting the file as a .obj file to import the model back into Archilogic, the materials are exported from blender internal and the changes in cycles are not taken into account.

Suggestion:
Add a feature to convert material information of an Archilogic blend file from cycles to blender internal (and back) to make sure that you don't lose material information such as assigned textures when trying to export the model to a format like OBJ.
