[Plugin]Export Collada with texture names 1.2b [30/9/11]

TIG

The last trap sorts out PC and MAC variants...
The bald Dir.delete(ref_dir)
WILL fail IF the directory contains files... so use
Dir.entries(ref_dir).each{|f| next if f=='.' or f=='..' File.delete(File.join(ref_dir, f)) }if Dir.entries(ref_dir)[2] Dir.delete(ref_dir)
This WILL delete any folder as it 'empties' it first...
EDIT: typo fixed

@TIG,

I get : undefined methodDir'` with that?

...and something else I find odd, a new Material folder was created and populated with materials, but none of these are in the 'undeleted' tmp Dir.

To clarify:
If I remove the 'tmp' Dir from the system. Start SU, open a drawing and RC, and then use this plugin.

I get a .dae and a populated Materials folder and I also have a new tmp Dir with the same materials inside, and the no method error.

if I then open a second drawing and use this plugin again I get another .dae and another populated Materials folder, bur the tmp Dir does not add these new materials and I get another no method error for Dir.

I don't understand....

I fixed all issues above (hope now it's right).
I also added that the plugin prefers the material's screen name as long as it's not generic.
This time I must have forgotten the require Sketchup. Thanks to all for the tips.

@driven: It works with
Dir.foreach(d){|f| }
and
Dir.entries(d)[2]

It works now, but when I checked the material names after importing them in Blender and Poser they are being renamed again.
There are no other plugins loaded into SU8... I just downloaded 8 and this is the first Ruby I added.

Sorry, stupid typo - fixed original so as not to confuse latecomers to the party

Excellent plugin (and initiative), Aerilius!

There seems to be a small problem with the texture paths though:

<init_from>**Boxes_MaterialTest/**C:/Users/ABC/Desktop/Boxes_MaterialTest/_Asphalt_Stamped_Brick_1.jpg</init_from>

As you can see it seems to add the name of the exported DAE file to the texture path. Once I've removed that I can easily import the DAE file with textures in Lumion

the folder does stop all the texture being scattered over you desktop, so maybe putting the dae file into it programatically would be better...

TIG

<init_from>daetest/C:/Users/TIG/Desktop/daetest/Palm14x.png</init_from>
should be either
<init_from>C:/Users/TIG/Desktop/daetest/Palm14x.png</init_from>
or for a [better] more general solution where the dae has its images in a folder 'kept with it' even when moved
<init_from>daetest/Palm14x.png</init_from>
The code is readily tweaked thus
fileNames.each{|old,new| colladaContent.gsub!(old,new) **colladaContent.gsub!(/#{dir+'/'}/,'')** } to remove the unneeded path...

Morten

Thanks for that, TIG - the textures work great now without the need to manually edit the paths!

Any idea how to preserve the original SketchUp material names in the DAE file?

That's what I've been working on (while I hadn't read all new posts here). I've also found the mistake myself and fixed it (I had mixed up the file base name and full path).
So now the plugin not only replaces texture file names, but also the material's screen names. It wasn't simple because collada has several different material names (<material>, <instance_material>) that are scattered over the whole file.

So you mean to put the collada file into the same folder where the textures are? I understand how that would be useful, for now I did only modify the contents of the dae and kept the file structure how SketchUp produced it.

Indeed it could be useful however note that it would be rather unusual. Most of the exporting packages I know place the materials into a subfolder under where the model file is. Would it not cause confusion rather than ease of use? When exporting, most (experienced) users create a folder to collect all exported files and subfolders anyway.

Hmm, after replacing your Ruby script with the latest version, the imported DAE object appears without textures in both Blender and Lumion.

I'm testing a simple box with 1 brick material + 1 default white material on the inside of the box, and as far as I can tell, there's still a slight discrepancy between the material names throughout the DAE file:

<instance_material symbol="[Brick_Rough_Tan]" target="#ID5">
<instance_material symbol="Material3" target="#ID15">

...

<triangles count="12" material="Material2">
<triangles count="12" material="Material3">

The texture re-appears if I replace "Material2" with "[Brick_Rough_Tan]", so it's almost working.

TIG

I too have noticed this BUT the SKP dae-importer works just fine
Perhaps these other apps need the image files to be with the dae - but the normal SKP dae-exporter version writes to a similar textures subfolder too ?

I have also played around with trying to adjust the material's names in the xml - you can convolutedly connect the textures to the materials and thereby get the real material's name... BUT changing them in the xml [manually] seems to do nothing because when you import the materials they are still called '<auto>1' etc anyway

F I N A L L Y !!!!!!!!!!!!!!

I LOVE YOU!

pep75

mmm....the love is over.....it doesn't do anything! Is it working? I'm importing the Collada-file into Cinema4d but I just got the "normal" material names......

Gaieus

What do you mean by "normal" materials names? Texture0, texture1 etc.?
Are you using this exporter? (File > "Export collada with texture names" and not File > Export > 3D...)?

pep75

Hey Gaius,

In Cinema4D I normally get "Material 1, Material 2, etc" instead of the material names I use in SketchUp. When I use the collada-plugin (file > export collada with material names) it really doesn't export it with the material names. I'm working with Windows and version 8...mmm

We can't see how to rename 'Materials' in a DAE file.
We can rename their 'Texture' files however.
SO depending on the app that you import into - all materials will become something like material0, material1 etc, or in a SKP <auto>1 etc.
Assigning a name to a material in the DAE is simply ignored and the app's imported materials are named using their simple numerical order in the DAE file.
However, if the material has a texture many apps will list that against the material, so you can then spot it by that image-name IF you've used this exporter-tool and had used sensible image names for textured-materials. With the native DAE exporter material1 will have a texture called perhaps texture1.png etc... but at least this tools gives material1 with ' brick_666.png'...

pep75

Aaaaaah...so only the names of TEXTURED materials will show up...mmm...well that means no improvement for me.......grrr....I could already see the linked texture-names in Cinema and the textures are clear to me wich material it is....well...

Thanks though!!
