Hi Furti,

many thanks for your addon.

I've got a problem resolving textures but I can't realy pick the Freecad release when it first started. Anyway I am working with your latest add-on release and this freecad environnment:

OS: macOS 10.14
Word size of OS: 64-bit
Word size of FreeCAD: 64-bit
Version: 0.19.17681 (Git)
Build type: Release
Branch: master
Hash: e94af7ff5e873f263cac51d7d47df68eca183250
Python version: 3.7.3
Qt version: 5.9.7
Coin version: 4.0.0a
OCC version: 7.3.0
Locale: French/France (fr_FR)

context
openging a project with some texture configured
erro in the Freecad report view and project file is open but textures aren't resolved

error msg

Traceback (most recent call last):
File "/Users/bblockmans/Library/Preferences/FreeCAD/Mod/ArchTextures/texture_config.py", line 272, in onChanged

children = node.getChildren()
<class 'AttributeError'>: 'NoneType' object has no attribute 'getChildren'

error comment

It looks like the shadedNode object isn't resolved in the texture_manager.py file (line 104) and

Code: Select all

                    shadedNode = faceset_utils.findShadedNode(switch)

and a "None" object is then used as parameter without subsequent test on parameter "nullity" before asling for it's supposed attributes

Code: Select all

                    brep = faceset_utils.findBrepFaceset(shadedNode)

faceset_utils.py (line 416)

Code: Select all

def findShadedNode(node):
    [color=#FF0000]children = node.getChildren()[/color]

    if children is None or children.getLength() == 0:
        return None

    for child in children:
        if child.getTypeId().getName() == 'SoBrepFaceSet':
            return node

        shadedNode = findShadedNode(child)

        if shadedNode is not None:
            return shadedNode

error details

when I then hit the space button on the textureConfig files all seams to work ok.
N.B.:

• I've got 2 texture config "textureTuileConcassees" and "textureBardageVertical". The error is hitten on the resolution of the first texture.
• I've added a print comment before the error line in the
  faceset_utils.py file e.g. "----- node :...."

Are we always supposed to find "shadedNode" object ?

Thanks for your help.

[furti]

Thanks for pointing this out. I think the problem only occurs, when you open a document where a TextureConfig is visible. Then it could happen, that the TextureConfig is executed before all view objects are set up correctly.

I added a fix for this. Now when no shaded node is found the object is not textured and a message, containing the object Label, is logged to the Report View. So one can easily see when a object is skipped because of a missing ShadedNode.

I don't know if there are Objects that have no ShadedNode. But it is possible that Nodes with other types of FaceSets will not be texturable with the current implementation.

Hi Furti,
thanks a lot. I downloaded your last commit and it's fixed.

Cheers

Hi furti,
sorry to botter again but I am facing with a problem on my freecad project files since the last FreeCAD comit (Version: 0.19.17798 (Git)) cf.https://forum.freecadweb.org/viewtopic. ... 11#p328211

Since this commit (but it was OK in earlier FreeCAD version) I am not able to resolve my ArcTextures anymore.

error
when trying to resolve te TextureConfig files I've got the following error

I don't know why but ArchMaterial object in the ArchTexture script is resolved as a dictionnary

Code: Select all

material = {'Color': '(0.762905317769131, 0.2041962310215915, 0.03569085221637293)', 'Description': 'tuiles en terre cuite concassées', 'DiffuseColor': '(0.762905317769131, 0.2041962310215915, 0.03569085221637293)', 'Name': 'tuilesConcasées', 'ProductURL': '', 'StandardCode': '', 'Transparency': '0', 'ViewColor': '(0.762905317769131, 0.2041962310215915, 0.03569085221637293)'}

and no more as a real python object? Hence material.Name is not resolved but material['Name'] would.

The thing is that when querying the material objet in freecad python console, the object is well resolved as a real pythonObject.


Sory againt but I hope you've got an Idea on this problem which isn't probably specific to your workbench?

Thanks anyway

[furti]

No need to excuse. Its important to report bugs when you find them. I appreciaze that a lot.

I had a look and found the problem. It is not about the material property of the objet to texture, it is the material itself that causes a problem. The mazerial has a "Material" property and since some commits it seems to have a "Shape" property too. So it is picked as a candidate for texturing as it looks like a texturable object.

I will try to provide a fix tomorrow.

[furti]

I pushed a fix for this. Now only objects with non null shapes will be candidates for texturing.

OK solved with your last git commits.

Thanks a lot

Hi furti,
You did a very nice your work with your FreeCAD ArchTextures workbench.
However I am really struggling to understand how I can use it. I have tried to follow the instructions of the workbench readme file (https://github.com/furti/FreeCAD-ArchTextures), and have created a material assigned material to my objects. But I am not able to figure out how performing them:

• Select the object in the TreeView
• Right click in the Data Tab and click "Show all"
• Right click again and click "Add property"

When I right click in the Data Tab there is no context menu that appears where I can select "Show all" and "Add property".
Do I need to use FC 0.19? I use the current stable version 0.18.4.
Thanks for your help!

Did you read the information in README.md?

Texture mapping

Currently Texture Mapping only works with objects that have a Material assigned. All architectural objects have such a property. To create a material, go to the Arch workbench and create a material there. See https://www.freecadweb.org/wiki/Arch_SetMaterial for further details.

...

From FreeCAD 0.19 onwards, it is possible to also texture objects created with other workbenches than the Arch workbench.

To use textures you need objects that have the "Material" property. In 0.18 only architectural objects, like Arch Wall, have such property.

Version 0.19 introduced many new underlying features, one of which is that now you can add properties in real time to any object in the tree view. So, in 0.19 you can add the Material property to any object that you have, whether it was created with Arch Workbench or not.
