I'd like to try JME3, I have in my JME2 application models built with 3dstudio and exported in 3ds format (then converted in jme format)
Which approach should I follow to use then (and create J3P archives)?
Thanks in advance
bye
You should import the 3DS models in Blender3D or your choice of modeling tool, and export them into Ogre3D Mesh.XML format. Sorry but this is the preferred way of handling models right now. In jME3, I've taken the necessary precautions so there's one, very well supported format, not many, badly supported ones.
thanks a lot, I did it, I exported from 3dstudio in to obj format, imported it in Blender and exported model in OgreFormat
the problem is that materials weren't red, except than for first one in .material file

I've update from svn revision 4801, and Asset class seems to miss (used in AssetCache)

I've seen you added it in revision 4802 (thanks !!!), but I think there's another problem when I try to loand an Ogre scene from a J3P file:
the method

thanks a lot for your nice job !!!
bye
edit--
with this changes in J3PFile.java seems to work:
private InputStream openStream(J3PEntry entry, String name, Access access){
try{
InputStream entryChan = requestRange(entry.offset, entry.length);
if ((entry.flags & J3PEntry.LZMA_COMPRESSED) != 0){
// wrap with LZMA decomressor
return new LzmaInputStream(entryChan);
}else{
return entryChan;
}
} catch (IOException ex){
logger.log(Level.SEVERE, "Failed to open stream: " + name, ex);
}
return null;
}
private InputStream requestRange(long offset, long length){
try{
ByteBuffer bb = ByteBuffer.allocateDirect((int) length);
channel.read(bb, offset);
bb.clear();
ReadableBufferChannel entryChan = new ReadableBufferChannel(bb);
InputStream in = java.nio.channels.Channels.newInputStream(entryChan);
return in;
}catch (IOException ex){
logger.log(Level.SEVERE, "Failed to open URL: ", ex);
}
return null;
}
