Re: Custom Lighting with Anisotropic Specular?
Ace, I didn't understand your version very well. So I just recreated it from the the HLSL code from that page. I didn't hook up the s_den from it though. Cause it just lightened the specular to basically nothing. This version is not as bright as if you were to hook it up the Antistropic Direction node. But I figure… -
Re: Custom Lighting with Anisotropic Specular?
Well I made the custom node. I'm using a green color now. I tried turning off Normalize and used a clamp instead. But it created more lines. I've changed a few of the nodes parameters. Such as multiplying by 15 instead of 180. Since 180 made it repeat over and over. Here is a comparison from the top. The only angle where… -
Re: Custom Lighting with Anisotropic Specular?
Removing any of the Normalize nodes that isn't the light vector or camera vector wacks it out even worse. And wouldn't the clamp work as the Max? I don't know enough about HLSL to actually write code for it. -
Re: Custom Lighting with Anisotropic Specular?
Ah, I see, I just tried recreating the shader from the snippet and you're right, I never noticed this, but it seems like the implementation on the Unity Wiki could actually be wrong, since at pure Horizontal, it still bends the highlight upwards. I also ran a few Max tests with their native Aniso shaders, seems like they… -
Re: Custom Lighting with Anisotropic Specular?
Not really, since UDK (IIRC for the open Clamp node) clamps it automatically between 1 and 0 again and you need to declare manually (or do it through the IF node) to get the correct math a la Max. Use a Custom node instead and put this in it: return max(A, B) ; Then expand in the input Bar in it, and Put in A and B for… -
Re: Custom Lighting with Anisotropic Specular?
UDK already Normalizes a majority of the Nodes, so try taking out the extraneous ones, but keep the one for the Blinn in the final part only. Also, for the Max node, just use a Custom node and declare the Max value. I think it's return; Max(A,B)? -
Re: Custom Lighting with Anisotropic Specular?
The red line is where its supposed to be lined up at. I've cut out a lot of the nodes. If I crank up the anistropic direction to lik 20, it does go to the center. But its way too thin. -
Re: Custom Lighting with Anisotropic Specular?
5e-005 is .00005, it doesn't matter what you put here just as long as it's really small. It's only there to keep the shader from dividing by zero. And the exp probably doesn't have to be made via a custom node, I just don't know how you would do it. -
Re: Custom Lighting with Anisotropic Specular?
hey guys you've been really helpful. I've been super-busy so I forgot about this thread, but now I'm glad I revived it :) Ace-Angel: does your implementation allow to change the specular direction? none of your nodes seem to be meant to be edited so where would you do it? All I ever got close to was an inexact aniso… -
Re: Custom Lighting with Anisotropic Specular?
Eh. I've tried to work it out for the past couple of hours for you. But something isn't working in this shader. I had been converting the HLSL from this site http://wiki.unity3d.com/index.php?title=Anisotropic_Highlight_Shader What I came up with was.. A direct conversion ( assuming I did it correctly), gives some sort of…
