Hello all,
I have this effect that aply the chrome in the model:
float4x4 matWorldViewProj;
float4x4 matWorldInv;
float4x4 matWorldView;
float4x4 matWorld;
float4x4 matViewInv;
float4x4 matView;
float4 vecSkill41;
float4 mtlSkill1;
float4 vecSunDir;
float4 vecFog;
float DoFog(float3 Pos)
{
// convert the vector position to view space to get it's depth (.z)
float3 P = mul(Pos,matWorldView);
// apply the linear fog formula
return saturate((vecFog.y-P.z) * vecFog.z);
}
void mainVS(
in float4 inPos : POSITION,
in float3 inNormal: NORMAL,
in float2 inXY : TEXCOORD0,
out float4 Pos : POSITION,
out float2 chrome : TEXCOORD0,
out float2 uv : TEXCOORD1,
out float oNrm : COLOR0,
out float Fog : FOG
)
{
// transform the vector position to screen coordinates
Pos = mul(inPos,matWorldViewProj);
// rotate and normalize the normal
float3 N = normalize(mul(inNormal,matWorldInv));
// Add fog
Fog = DoFog(inPos);
// convert texture coordinates or do other stuff
oNrm = mul(inNormal,matWorld); //pass normal
chrome=mul(N,matView)*mtlSkill1.x; //mtlSkill1 contains the scale of the reflMap
uv = inXY;
}
texture mtlSkin1;
sampler basemap = sampler_state
{
texture=(mtlSkin1);
MipFilter = LINEAR;
MinFilter = LINEAR;
MagFilter = LINEAR;
//AddressU = Mirror;
//Addressv = Mirror;
};
texture entSkin1;
sampler entskin = sampler_state
{
texture=(entSkin1);
MipFilter = LINEAR;
MinFilter = LINEAR;
MagFilter = LINEAR;
};
float4 mainPS(
in float2 chrome : TEXCOORD0,
in float2 uv : TEXCOORD1,
in float iNrm : COLOR0
) : COLOR
{
//change shinyness where "2" stands , play around whith it till it fits your needs
//skill41-43 contains rgb values, skill44 contains power value
float4 result=0.5*dot(tex2D(basemap,chrome),vecSkill41.w)-0.5;
//change the "2" below to adjust the shyniness, too
result*=result/2+float4(vecSkill41.xyz,1)*tex2D(basemap,chrome);
float sunL = 0.5*dot(iNrm,-vecSunDir)+0.5; //sunLight
//return (result-sunL+tex2D(entskin,uv))*pow(sunL,2); //dark metallic, mixed with entSkin1
return (result+tex2D(entskin,uv))*sunL; //standard, mixed with entSkin1
}
technique better_looking_chrome
{
pass base
{
//CullMode = none;
VertexShader=compile vs_2_0 mainVS();
PixelShader=compile ps_2_0 mainPS();
}
}
technique fallback_chrome
{
pass base
{
//CullMode = none;
VertexShader=compile vs_1_1 mainVS();
PixelShader=compile ps_1_4 mainPS();
}
}
and the script for the function is:
bmap chrome_lookup=<cromo.tga>;
material mat_chrome
{
skin1 = chrome_lookup;
effect="chrome.fx";
}
function chrome()// chamar essa função no script desejado.
{
my.material = mat_chrome;
my.Skill41 = float(random(2)-1); //r
my.Skill42 = float(random(2)-1); //g
my.Skill43 = float(random(2)-1); //b
my.Skill44 = float(1.0); //specular power
mat_chrome.skill1 = float(1); //reflectmap scale
}
My question is: how do i to aply the effect only in the first skin of the model ? This effect act in all the skins, and no only in the part that i want in model.
For example, the model have 3 skins made in MED (skin0, skin1, skin2) and i want aply the effect only in the skin0 or skin1.
OBS: don´t works aplying the effect in MED, i tried this.
