Correct way of handeling several different types of light

Thanks a lot for you post, sometimes the internet makes me question why I need to spend lots of money to go to university.
It seems like there is no perfect way of having a shader that can handle lights like I want it to. Do you know how this is... |

Actually, there is no if statments at all in my code.
If the compiler is unrolling my loops like that, will it not be a very expensive shader? What im trying to do is write a shader that supports a given number of lights, but they can all be of d... |

There was two errors in the code.
The first one was the one Hodgman pointed out. I feel somewhat embarrassed for not spotting that one myself.

Blade like dissolve effect

Accessing multiple textures in shader

Hey I have been working on this the whole day and I have made some progress. It looks like the textures are fine and I can access both of them. The reason why I could not see the second one is that it was not in the "correct" position.

Accessing multiple textures in shader

I looked at it in PIX as you suggested, and it all looks fine to me (but then again, I have never used it before)
Here is all my render targets. (Why is there so many? I only create two)

No, it makes no difference.
It might be related to the problem, not sure, but when I change rendertarget, my screen goes purple and everything I have drawn up until that point gets removed. |
