GZDoom modeldef question

In the modeldefs lump, i have the following code:

Model DualPistols
{
   Path "models/dual"
   Model 0 "tris.md2"
   Skin 0 "skin.pcx"
   Scale -1.0 1.0 1.0
   FrameIndex DUAL A 0 11
   //etc, etc, etc
}

Now, I do NOT have a sprite named DUAL anywhere in my pk3, but for some reason GZDoom tells me that it is an unknown sprite. I was under the assumption that there does not need to be a sprite counterpart for a model, and that one could simply create sprite names in the modeldef lump. Do I need to add sprites with corresponding names? Do I have to use an iWAD sprite name for this? Is there something which I am missing here?

Models need sprites to exist, for some reason. So you'll need to have the sprite DUALA0 somewhere for that model definition to work properly.

I've got no idea why.

In b4 Fraggle changing the thread title and scolding to use more descriptive thread titles.

Thanks, that clears that up. I actually just put a "blank" sprite in named DUAL (no A, or anything else) and surprisingly, it works now for all frames of my model. Weeeeiiiiirrrd.

I think I'm going to bug Graf about this now.

That's because the underlying engine (i.e. ZDoom) needs the sprites to work at all.
