OSP Shaders Barabas' shaders

[Mammoet]

Hello!

I heavily edited the shaders for warband and I would like to share
Beware, this is only for modders, not adviseable to apply to any existing mod without tweaking it!
If you don't know what this is, it;'s probably not for you.

Most important new features:
-Colored specular maps
-Parallax shaders
-Better looking envmap shaders for swords (and other metals)

It might be that the speculars are a bit bright (like 10 times or so...). Easiest way to fix this is change the "SpecularCoef" in the module_postfx.py

Use at your own risk and enjoy!

Finally!  I guess , Its very useful for everyone, thanks a lot 

 

[Woelfie]

I've been waiting for this . Thanks for releasing it Barabas, It'll come in handy I'm sure.

Wolf.

 

[Pumpkin Lord]

This will surely be in safe hands, you are awesome.

wish i had a youtube link with an isolated sample of dr.dre going "helll yehhh"

Nice work Barabas. Thank you.

 

[Mammoet]

I updated them with some minor fixes. It's what I use at the moment so it should work. If there are any problems/issues you're free to post here and I'll take a look at it when I have the time =)

 

[Swyter]

Wow, parallax is much easier than I thought at first. Thanks for clearing it up.

Oh. What's with the FXO renamed as FX in the distribution pack?

Barabas, mate. I'm trying to implement derivative maps in SWC. Can you help me with that?
It just doesn't makes sense to me.

It's so you warband can read it from the module directory. It doesn't understand it if there are fxo's. Unless I have been misinformed ^^

Edit: lol, I only now see that you are asking about derivative maps. I'll take a look at what it is. =)

Edit2: Looks very interesting. I'll try it out after dinner. I don't quite get it completely yet, but it doesn't look too complicated.

Unfortunately my gpu died last weekend, so now everything looks like **** and I have to run Warband at 800x600 to get playable fps. Here I upped my shader settings and a bit my texture quality too. And I have blender in the background, so my fps is ****. Apart from that I'm pretty sure it could be a lot better =D. Anyway the first implementation attempt looks like this:

Spoiler: crappy image

PS_OUTPUT ps_main_g(VS_OUTPUT_G In, uniform const int PcfMode)
{
	PS_OUTPUT Output;

	// float2 height_grad = 2*tex2D(NormalTextureSampler, In.Tex0).rg-1;
	float height = tex2D(NormalTextureSampler, In.Tex0).b;
	float3 position_dx  = ddx(In.Position);
	float3 position_dy  = ddy(In.Position);
	float  dBs     		= ddx(height);
	float  dBt 			= ddy(height);
	// float2 uv_dx 		= ddx(In.Tex0);
	// float2 uv_dy	 	= ddy(In.Tex0);

	// float  dBs   		= height_grad.x*uv_dx.x+ height_grad.x*uv_dx.y;
	// float  dBt 			= height_grad.y*uv_dy.x + height_grad.y*uv_dy.y;

	float3 surface_gradient
					    = dBs*cross(In.Normal, position_dy) +dBt*cross(In.Normal, position_dx);
	surface_gradient   /= abs(In.Normal * dot(position_dx, position_dy));
	float3 normal       = normalize(In.Normal - surface_gradient);


	float shade         = saturate(dot(vSunDir, -normal));

	if ((PcfMode != PCF_NONE))
	{
		shade          *= GetSunAmount(PcfMode, In.ShadowTexCoord);
	}

	float3 color        = In.Color + shade*In.SunLight;

	float4 diff_tex     = tex2D(MeshTextureSampler, In.Tex0);
	INPUT_TEX_GAMMA(diff_tex.rgb);

	Output.RGBColor.rgb = color*diff_tex;
	Output.RGBColor.a   = diff_tex.a*In.Color.a;
	// gamma correct
	OUTPUT_GAMMA(Output.RGBColor.rgb);

	return Output;
}

technique diffuse_gradient
{
	pass P0
	{
		VertexShader =  compile VS_X vs_main_g(PCF_NONE);
		PixelShader = compile PS_2_X ps_main_g(PCF_NONE);
	}
}
technique diffuse_gradient_SHDW
{
	pass P0
	{
		VertexShader =  compile VS_X vs_main_g(PCF_DEFAULT);
		PixelShader = compile PS_2_X ps_main_g(PCF_DEFAULT);
	}
}
technique diffuse_gradient_SHDWNVIDA
{
	pass P0
	{
		VertexShader =  compile VS_X vs_main_g(PCF_NVIDIA);
		PixelShader = compile PS_2_X ps_main_g(PCF_NVIDIA);
	}
}

DEFINE_LIGHTING_TECHNIQUE(diffuse_gradient, 0, 0, 0, 0, 0, 0, 0)

EDIT:
I updated the code with my latest version. The commented stuff is for the derivative maps.
The main problem is blockiness. And I'm not sure it works correctly actually. I also didn't get it to work with the derivative maps (which is actually the same as normalmaps with 2 components, just with the tangent space replaced by all this ddx stuff in the pixelshader.). I'm giving up for now. If anyone else manages to get better results let us know =)

Very nice. I shall be researching into this!

Link is dead.
Can somebody upload it elsewhere as a mirror?

I'm also blocked from Gamefront (Spain is on the disallowed list). Used a quick proxy for getting it anyway:

True love for you Swy. <3

-Better looking envmap shaders for swords (and other metals)

any example barabas?

 

[Mandible]

Yeah, I feel like this page would really benefit from some example screenshots.

 

[Lumos]

I tried these a while after they came out and they did produce some rather odd effects for me, so I'd also be glad if there were example screenshots.

 

[thick1988]

Yes, examples please.

 

[Wojciech Bator]

gamefront doesn't work for me :/
