| Hi guys, Some time ago i watched a demo, in this demo you have something like 256 lights on screen at the same time... anybody remember this?, iŽd like to have it but i lost the link thanks, |

| You're probably mistaken. The limitations of DirectX make this technically impossible. |
| ||
| You need to do render-based cubic lighting(As opposed to multi-pass), then additional per-pixel/colored/even specular lights add about 4 polys worth of overhead, I've had 50 close by per-pixel lights running in cryo no probs. |
| ||
| Gfk: is it not possible to multirender, repositioning the lights each time? |
| ||
| Cygnus: no; it's a limitation of the real-time hardware. If the demo you mention is the demo I remember they were 'faked' sprite lights, balls bouncing against the walls and 'flashing' when they hit. That's all faked. You can never plan on more than 8 hardware lights available for any given card, though some have more. |

| I remember the demo about 2 years ago. I think they were sprites or quads aligned to plane You could also use the LightMesh command but I just tried the example and it seems to be broken. |
