I am working on a game that i will have vehicles in. I wanted to use the Bugatti Veyron Super Sport as my first car (i love the hell out of that car). So i googled models of the car in Sketchup which is my primary 3d rendering software (along with blender). I found one i liked, loaded it up, exploded all of the groups, and used my Ogre XML converter to convert it into a mesh. I took all the files and put them in a subfolder under my assets. Then i converted the mesh to .j3o. When i attempt to open the model though, it says:
Error opening bugatti.j3o
no stack trace, no error code, nothing.
this has happened with almost every model i have found, from sketchup to 3ds max.
im wondering if its the complexity that crashes it, but i don’t think that should be a problem.
anyway, anyone who has a fix PLEASE TELL ME. i need to get this project rolling.
EDIT: a developer showed me the obvious little button in the corner (i feel stupid now) I couldn’t make out what was wrong but here is the read out:

There should be a red icon on the bottom right of the screen, can you try clicking it?

Which version of jME3 are you using? Can you provide the J3O file?

i am using the latest stable version and here is a link to the j3o (has all the data from the model)

You can’t use the “<” and “>” characters in material names. This is the actual exception that happened:
[java]org.xml.sax.SAXParseException; lineNumber: 272104; columnNumber: 28; The value of attribute “material” associated with an element type “null” must not contain the ‘<’ character.

i went in and changed the materials the person used (two of them were surrounded in <>) and now it does not have an error on loading it...but it doesn't show anything in the scene window :/
EDIT: i was able to add the ogre xml to a scene via the "add in scenecomposer" button and it was outrageously huge, which is fine, its just a size problem BUT, the j3o still seems to produce nothing when i add it in
EDIT 2: nevermind......i found it :)......you would think that sense its as big as life i would easily find it, but no, i had to search for it
PS THANK YOU SO MUCH I LOVE THE ENGINE AND AM HOPING TO MAKE A SUCCESSFUL MMORPG WITH IT THANKS TO YOU I CAN CONTINUE THE PROJECT :D:D:D:D
