deformVertexes autoSprite issue with Opengl2

This shader entry doesn’t seem to work with the Opengl2 renderer.

Im currently trying to render a sprite on my Mega Heath model. I would show you, but I can’t post pics unfortunately (lords knows why…)
Anyway, it looks fine in Opengl1, but does not display at all in Opengl2

Not expecting this to be instantly fixed, but I thought I would bring it to your attention since it may be a simple bug to fix.

Cheers.
