I had a look through this... like you say there's certainly no obvious
reason for it not to work.
Just one thing though, you don't show that youv'e precached the sprite... I
know you probably have if not it wouldn't compile, but just try changing....
WRITE_SHORT( m_iSpriteTexture );
to this:
WRITE_SHORT( g_sModelIndexFireball );
As a temporary measure to make sure the sprite is getting called properly.
Mike.
