Chthon Brightness

I just noticed a peculiar behavior of the Quake engine regarding the Chthon monster. For some reason its brightness differs depending on the side he's facing - basically normally lit in the direction he starts from, and considerably brighter when he turns around. It's noticable in all engines regardless of overbright support, and in some cases looks pretty bizarre.
Anyone know what's going on there? Is it a "feature" and why?

That's part of the gouraud shading/surface normals. You can also notice it by watching the viewmodel while you spin round in a circle - at different angles it will be brighter or dimmer. The effect is probably most noticeable on a large model. I think that for this kind of directional shading the quake engine renders as if there is one fixed light source, coming from above at a particular bearing. I've never found which bit of the renderer does it though.

i think there's a lookup table the game uses to generate light value based on vertex normal.... anormdots.h or something.

czg: cool, it's certainly got the visuals down.
negke: iirc in stock quake light direction always faces north and overall brightness gets modulated by the lightmap texel the player is standing on.
of course some engines decided to do it less hacky. I think FTE even generates a light grid upon runtime.

Waiting for the UPS truck to come and deliver Oculus Rift today.
Guess it might be interesting to visit some old familiar places with it.
Can't see the issue really. It's his game and he can stop making it if he wants.

thanks for the link. My favourite part was when Carmack said he got pretty far into rewriting Wolfenstein 3d in Haskell. What a bloody nutcase.

Why the fuck are my graphic card's fans running so fast and where the fuck is the fan speed control hidden in the options? Win7, latest stable nvidia drivers.

If you can live without support, I use OVH:

Steam requires me to enter a code from a mail they sent me because OMG YOU USE NEW DEVICE. I manage my mail in Linux. So I have to reboot to Linux, get the mail, reboot to Windows. 3 times in a row this fucking joke tells me the code has already expired but does not even say how long it is valid. What the fucking fuck? I hate everyone for this.
