Purpose of face_invul1?

[pehi]

Hey guys,

I did some research about the mentioned hud component, so far I only figured it supposedly isn't used, so what's the purpose? It seems it should be displayed when you have pentragram and quad at the same time, but it THAT event the face_quad is loaded.
Clarification would be awesome.
Cheers.

i guess people were hoping lordhavoc would add support for the graphic to darkplaces

It is very strange, since it is unusable, why bother to make the image? Most, if not all hud face packs have it, quite an obscurity. Thanks for the response nonetheless talisa.

yeah it was the idea to show it when you had both quad and pent at same time,
but darkplaces never actually implented support for using that graphic when both powerups are active at same time

im sure you could make it show when quad and pent are both active using CSQC though
