I use Blender 2.48 for making 3D contents.  
  
  
But I face some problem. please tell me why ?  
  
  
  
  
  
1. I made “A Simple Winter Scene” that is tutorial at [http://biorust.com/index.php?page=tutorial\_detail&tutid=81&lang=en](http://biorust.com/index.php?page=tutorial_detail&tutid=81&lang=en)  
  
  
and I export this scene to the Collada 1.3.2.  
  
  
but the Collada2PODGUI.exe/Collada2POD.exe nothing to do with exported collada file.  
  
  
really nothig. no message. no output. but program execute finish.  
  
  
Why ?  
  
  
  
  
  
2. then, I export this scene to the Collada 1.4. the Collada2POD works.  
  
  
but when I open pod file that created Collada2POD using PVRShaman, I got many errors as follow. The PVRShaman show gray scaled 3D image.  
  
  
Why I got these error ? what feature can I use for materials ?

&nbsp;
  

Collada2POD only supports&nbsp;the Collada 1.4.1 schema so this is why your scene wasn't converted.

&nbsp;
  

I've had a quick look at the tutorial so what I say may be incorrect but I think the reason Materials 'Orange' and 'Snow' failed is because they are just&nbsp;a colour and PVRShaman only supports materials that have a texture or a shader.
  

&nbsp;
  

The 'Fir Tree' material appears to be failing because the meshes it has been applied to don't have UV coordinates. If you're using&nbsp;Collada2POD GUI do you have 'mapping channels' ticked? If&nbsp;it is ticked or you are using the command-line version&nbsp;does the collada file contain UVs for those objects listed?

Did you enable the 'export controllers' option in Collada2POD (assuming you're using the GUI)?

Thanks. I add the UVTexture&nbsp;to Mesh. The error has gone and the 'Fir Tree' got textured Image in PVRSharman. but when I change texture image file, 'Cone' still has previus image. Do you know why ?

Yes. I enabled the 'export controllers' in Collada2PODGUI. (yes, I use the GUI)

&nbsp;

  

&nbsp;
  

I had following mismatch between Blender and PVRSharman.
  

1. The scene on PVRSharman is rotated. It's top view.
  

2.&nbsp;The Camera Location is different.
  

3. The Opacity for any material&nbsp;is 0. When I change to 1, I can see it.
  

&nbsp;
  

Do you know why ?

No I'm afraid I'm not able to replicate the problem here.

The way transparancy was described in the collada file was changed between 1.4 and 1.4.1 so collada files exported using a 1.4 exporter&nbsp;will end up with the opacity set to 0 when converted with Collada2POD.

Would it be possible for you to send your collada file to devtech@imgtec.com so I could take a look. I can also find out why you aren't seeing the animations.

Do you have plan for Collada2POD support these two collada versions ?

Hi,

&nbsp;
  

Thanks for the files I was able to reproduce the problems you are seeing and they look like possible bugs in Collada2POD. I'll have a look at fixing them as soon as possible.

No plans at present though I may see if I can add a special case for the zero opacity.

I'm afraid I haven't had a chance to take a look yet so can't give you a date when it will be done by. I'm hoping I'll get a chance to next week but can't promise anything.
