Lightning problem

[haraldsegliens]

Hello

The problem is that the dynamic light doesn't light brush entities, but it lights only model entities.

The code where the lighting is:

Code: Select all

int C_FireBall::DrawModel( int flags )
{
   if ( gpGlobals->frametime > 0.0f && !m_bUpdated)
   {
      m_bUpdated = true;
      m_vecLastOrigin = GetAbsOrigin();
   }
   pEffect->StartEmission();
   pEffect->StartRender(VMatrix(Vector(0,0,0),Vector(0,0,0),Vector(0,0,0)));//x,y,z

   if ( m_bLight )
   {
      dlight_t *dl = effects->CL_AllocDlight( index );
      dl->origin = m_vecLastOrigin // moving orgin;
      dl->radius = fire_lightradius.GetInt()//it's 2000;
      dl->decay = dl->radius / 0.05f;
      dl->color.r = 255;
      dl->color.g = 192;
      dl->color.b = 64;

      dlight_t *el= effects->CL_AllocElight( index );

      el->origin = m_vecLastOrigin;
      el->color.r = 255;
      el->color.r = 255;
      el->color.g = 192;
      el->color.b = 64;   
      el->radius = fire_lightradius.GetInt();
   }
   return 1;
}

Please help me.

You could add a very small model to the world, change its alpha color so that its invisible and set the dlight on that model and then adjusts its possition to match the fireball.

Ive experimented with the d-lights, its a performance drain. I didnt notice it on my i7 dev machine but the testers would experience massive fps drop.
Its also bleeds through walls and floors, they are really not worth it in my opinion. They use up lots of your precious development time and cause lots of frustration

We need some deferred shading, I'm pretty sure that's what the UDK uses and it says it can support hundreds of dynamic lights.(Not shadow casting which I think requires the forward rendering approach)

Trust me when I say you do not want "hundreds" of dynamic lights in UDK.

CryEngine 2 has deferred lighting.

Though, hundreds was not completely true. As that demo had 123 dynamic lights.


Also, you mean CryEngine 3. [Crysis = CE2] [Crysis 2 = CE3]
