Problem opening model in blender

[Timas]

Hello,

I'm having trouble opening one of the existing models in Blender. I'm interested in playing around with it for a little before trying to make something completely new and sending it in. Any chance anyone can give some hints?

This is the error I get when opening one of the .dae files:

Compiled with Python version 2.6.2.																					   
Checking for installed Python... got it!

	stringvals = ReadContents(xmlNode).split( )

fyi:

blender -v
Blender 2.48 (sub 1) Build

Any ideas or pointers?

Thanks!

For some reason I have never been able to import a Collada file into 3DS Max either. Hopefully someone can have some insight for both of us.

I played around a bit more and Sketchup Pro 7 and Photoshop CS4 with it's (limited) 3D capabilities both fail to import the files as well..

I really hope there's someone who can share some insight

If you have some knowledge of Python or are feeling adventurous, you might try wrapping the ReadContents call (xmlUtils.py:119) in a try/except block and printing xmlNode. With a little luck (I'm not familiar with the Blender code and can't have a look ATM), that will display which XML node is apparently missing (or failing to be read), and maybe we can just add that to our .dae file.

Timas, it's strange that you can not import dae file into blender. I've just tested the same file (0.AD/trunk/binaries/data/mods/public/art/meshes/structural/hele_tric.dae) with the same blender version and it imported OK. I have attached my screenshot (Mandriva Linux x86_64 Cooker).

PS. There is the choice between COLLADA versions (1.3.x or 1.4) when importing file and I've chosen version 1.4 (see screenshot 2).

Olelukole, I'm just going on a whim here.. did you install any specifics maybe? A Python lib? And which version of Python do you have?

I have been using the 1.4 version of the Collada import.. I'm glad to see it worked though, that's good news in regards to getting it working on my end as well

I haven't installed anything special . All the progs and libs are packages from Mandriva Cooker repository (development branch that will eventually be mandriva 2010.0). Here are some package versions I have installed:

blender-2.48a-8mdv2009.1.x86_64.rpm

python-2.6.2-4mdv2010.0.x86_64.rpm

python-imaging-1.1.6-7mdv2010.0.x86_64.rpm

yafray-0.0.9-5mdv2010.0.x86_64.rpm

And a lot of different libs that blender depends on, including xorg 1.6.3 and gcc 4.4.1 libs. Here is the full list:

Took some mucking about, but I got it working

I downloaded the 2.49a (Ubuntu deb) version of blender and it was insistent on having python 2.5, I gave in, installed 2.5 and voila, working import!

Now to see if I can do anything with this

----

edit: It's not as sunny as I hoped it was

celt_char_a.dae works, but so far the bigger files give the same errors as before

It has been a while, but I think I remember that there might be a difference in the capability regarding importing of animation vs. static .dae file. Or perhaps that was pmd and psa files... I forget.
