Sorry to ask this noob question but…
How do you activate VBO on a static obj model ?
because binaryReader returns a Node and setVBOxxx method apply to a Geometry…
I know it must be simple but i can't see it… :roll:
Thanks for answers,
bye,
Adenthar
Here's a simple class I wrote to make something like that easier. It's part of the FurBallz source:

Hope that helps!
Wonderful Renanse 
And another question… must we ask the renderer if it supportsVBO before applying or we can set it to true and it will not do it if it's not supported without error ?
jME will ignore VBO if it can't use it.
That's just great 8)
Thanks again Renanse.
