Why not using VBs & IBs in Irrlicht?

I'm puzzled that all rendering method in Irrlicht using DrawIndexedPrimitiveUP().
Yes, I'm noticed that it would work more effective when rendering lots of little calls ,e.g. UI things.
If I using batchs of models which have 1000-5000 faces, DrawIndexedPrimitiveUP() would pay a lot of time on create/copy/destroy VBs.

How about you guys?
Did u add VB&VI support and using DrawPrimitive() / DrawIndexedPrimitive() in your engin ?[/u]

There is VB and IB support in irrlicht. But you have to tell the engine to use them. Take a look at the doc.

Yeah...I see.
Thank u!

The version of my Irrlicht is 1.4.2, and 1.5 already support VB&IB.
I'll update my local engin.
