Dynamic shadow angles in Source 2007

[dark0r]

Hi all,

I just wrote an article on the developer wiki explaining how to implement Left4Dead style player/entity shadows in Source 2007 (Orangebox) mods. With these changes, walking by bright lights will change the direction of your shadow.

Note: this will have minimal effect on performance, which is great news!

Very nice.

[Gambini]

That would be a great effect i´d love to add in my mod. Too bad i know shit about coding.

Hey! it would be cool if someone could uptade this mod including this code and a few others like that fix for ambient_generic

Thanks guys. The same effect is also noticeable in several Counter-Strike: GO screenshots

Shit, Kremator found out, now he wants it in Canvas.

Congrats darkOr, you are now officially contributing to Canvas.

Perhaps i misssed something or im using the wrong codebase but i had to add

void UpdateShadowDirectionFromLocalLightSource( ClientShadowHandle_t shadowHandle );
const Vector &CClientShadowMgr::GetShadowDirection( ClientShadowHandle_t shadowHandle ) const;
void UpdateDirtyShadow( ClientShadowHandle_t handle );

to the class definition before it worked.

OK, it's working great, but the shadow switching between two lights is... odd. Is it possible to have multiple shadows (one fading in, one fading out, for each light in the neighborhood) this way, or would that not be possible?
Assuming you already investigated that, i guess it's an obvious next step.

Tnx!

He is currently working on fading/color changing shadows. He has to localize them(currently changing the color/alpha of one shadow affects all).

Multiple shadows sounds interesting, I don't see why it can't be possible.

Thanks zombie, added the steps to the article now.

I was thinking about multiple shadows myself, and will give it a shot when I get per-entity shadow colours functional. I will add a ConVar such as r_worldlight_shadowsperentity which will define the maximum number of shadows an entity may have. The brightest lights around an entity will then cast independent shadows, instead of the most intense light casting a single shadow.

In the meantime, try increasing r_worldlight_mincastintensity, or decreasing r_worldlight_lerptime.

this is pretty stunning. I'm looking forward to seeing those multiple shadows. I wonder how high in number it can go?

[dark0r]

Independent shadow colours have now been implemented:


Next step is multiple shadows (at varying alphas).

You are my GOD !

I wait a long time to see a tutorial like this !

Thank you VERY MUCH !!!

Can't wait to implement it !

EDIT :

I implement it, no error of compilation, juste, game crash on launching a map...

REEDIT :

That work only for certain map, not for all... it's strange...

REREEDIT :

I found the problem, if you have no light_environement in your map, the game crash ! ^^

So I hop you can fix that and add multiple shadow !

Thanks for all !

saul great work, and i do not think csgo has done this. its the same old sun casts the shadow in the current beta.

[joe_rogers_11155]

@cashed: they will probably include it as beta draws closer into final.

[IBeMad]

Any update on multiple shadows per entity?

[dark0r]

I've been busy with exams since the end of November, so unfortunately not. They finish tomorrow, so I'll get straight back to work, don't worry... I haven't left them.
