Hi  Grin

It is my first tests with VBO and, of course, it is not working.
LWJGL is complaining that I use VBO and none VBO rendering (what I do). I was thinking that it should be possible if I unbind VBO after use. Am I wrong ?

There is my rendering code with vbo :

Darmn, I just have to post my problem to find out my mistake  Tongue

IntBuffer are GL_UNSIGNED_INT and not GL_INT when using GL11.glDrawElements... Really confusing exception message but since there was an opengl error, VBO unbinding was not working properly.

Sorry  Wink
