<DIV>So far they have fixed a couple of bugs that I reported by the next day.</DIV>

<DIV> </DIV>
<DIV>Blender has a site called the blender model repository, </DIV>
<DIV> </DIV>
<DIV><A href="http://e2-productions.com/repository/index.php">http://e2-productions.com/repository/index.php</A></DIV>
<DIV> </DIV>
<DIV>I used some of the models in this repository to test out Export to X3D and to submit some bug reports. Blender also has an Export to Collada in release 2.5.5 so you can generate a collada file from the blender model as well.</DIV>
<DIV> </DIV>
<DIV> </DIV>
<DIV> </DIV>
<DIV> </DIV>
<DIV><BR>> Perhaps we should build and publish a small conversion archive.<BR>> <BR>> > However, some of these blender scenes can be quite large, a <BR>> few meg in size when converted to collada, and X3D-Edit <BR>> complains that they are too big.<BR>> <BR>> Netbeans (and thus X3D-Edit) has a problem with files larger <BR>> than 1-2 MB.<BR>> We are hoping that this gets fixed eventually.<BR>> <BR>> Also, X3D-Edit was not able to convert this Collada file <BR>> to X3D which was taken from chapter 9 in the book and Exported <BR>> from Blender.<BR>> > http://dl.dropbox.com/u/5095342/Models/demo_scene_chapter_09.dae<BR>> <BR>> > Do you know why X3D-Edit can't convert this scene to X3D.<BR>> <BR>> file size (in Netbeans/X3D-Edit) looks to be the culprit<BR>> <BR>> > This 2 step conversion process, first to Collada and <BR>> then to X3D is one way to test, correct and compare the results <BR>> from what the Export to X3D function provides in blender.<BR>> <BR>> another way to do this would be to directly invoke Xj3D converter.bat<BR>> or converter.sh script from command line<BR>> <BR>> i have previously had some problems with path handling in this <BR>> script, you<BR>> might have to work in local directory. sorry but i can't <BR>> test that further<BR>> due to some other issues on my machine.<BR>> <BR>> </DIV>
<DIV>I didn't realize that you could convert from collada to X3D from the converter.bat file. I tried it on one of the files but it didn't work because it said that the material shininess value was above 1.0 and stopped the conversion.</DIV>
<DIV> </DIV>
<DIV>Here is a picture similar to blender model that I tried to convert.</DIV>

<DIV> </DIV>
<DIV>and here is the result I have so far after performing an Export to X3D from the a recent version of Blender with some editing of the X3D file.</DIV>

<DIV>This was taken from the book "Blender Foundations" which also has some sample blend files for each of the chapters in the book available here.</DIV>
