Thank you Bond1!

How about a outer-glow style pickup like in Left 4 Dead and Left 4 Dead 2? Any help to start that effect?

It's easy not to get lost when you have no idea where you are going

Looks great. Just saw the movie last night. haha..

Besides that a dynamic enity already gets my atention in game because of the lightning issues, this is a great awesome tool, to make it a purpose. HAHA

Great work, bond1.

Have you checked out my dynamic entity shaders in The Metro Theater? They pick up their lighting direction from FPSC, and lighting attenuation from the lightmap color they are sitting on, so they integrate into the environment MUCH better than any stock media.

Interesting... Can you speed up the flash at all?

Very easy to do, find this line in the shader:

float3 Ln = float3(1500*sin(Time*3),0,1500*cos(Time*3))-IN.WPos;

The numbers in bold control the speed of the rotation, higher is faster.

By the way, the "1500" numbers are the radius of the light orbit. Larger numbers make a larger orbit - might get some interesting effects by changing those numbers too. Since they are the same, the light orbit is perfectly circular. Making them different would make an elliptical orbit.

Is there a way to make it where the item has a stronger glow?

Gosh, you guys...never happy with anything "out of the box".

Find this line:

float4 diffuseContrib = diffuse *3* lighting.y *SurfColor +(AmbiColor*diffuse);

Change the "3" to a higher number, maybe try 5 for starters. Too high and you'll blow the model out with light, but maybe that's the effect you want.

Yeah me too, and I am hunting for the tuts myself.
I did a simple search and found this site that seems to have some detailed info, but I haven't played around with it yet.

Hey Bond1, the flash in-game doesn't seem as strong as it is in the video. Does it require anything?

@bond1

Really like this shader. I'm expecting to see this show up in a lot of games soon!

ONly D2 and D textures. It is also dependent on overall ambient light as well as lightmap color. If you wish to remove this the lightmap dependency, find this line:

[i]float4 diffuseContrib = diffuse *3* lighting.y *SurfColor +(AmbiColor*diffuse);[//i]


And remove "SurfColor" from the equation. Or alternatively, change the 3 to a higher number if you wish to keep the lightmap dependency.

Ok. I think I know what I did wrong.

I think when I edited some of EAI's guns to be scifi [/plug] I wrote over both the D and D2 with the same image. I'll fix that.

Thanks!
