This resource changes the shading on most objects, making them look like this .

Changes:
shaders\common\lighting\advanced\vectorLightP.hlsl, line 203

Code: Select all

   float dotNL = dot(-lightDirection, normal);

to

Code: Select all

   float dotNL = clamp(smoothstep(0.4, 0.43, dot(-lightDirection, normal)), 0.2, 1.0);

shaders\common\lighting\advanced\pointLightP.hlsl, line 163

Code: Select all

   float nDotL = dot( lightVec, normal );

to

Code: Select all

    float nDotL = clamp(smoothstep(0.4, 0.43, dot( lightVec, normal )), 0.2, 1.0);

shaders\common\lighting\advanced\spotLightP.hlsl, line 99

Code: Select all

   float nDotL = dot( normal, -lightToPxlVec );

to

Code: Select all

   float nDotL = clamp(smoothstep(0.4, 0.43, dot( normal, -lightToPxlVec )), 0.2, 1.0);

A more difficult to install version that includes object outlines is currently in progress.

Looking good! Are there options in the editor, or it works only on code?

Can't wait for the outlines!

[Steve_Yorkshire]

Here's an old outline shader, incase it helps.

Nice! Thank you!
Going to tweak my light attenutation in 3..2..1..

Anyone get this working in any of the newer T3D builds under DX11? The shader code is a bit different now.

[TorqueFan]

Ah, nevermind. The one-line change is still relevant - I just didn't search well enough for it the last time!

For the most part, changes in the hlsl shaders you need are (glsl remain the same)

Texture Sampling:

Code: Select all

// Old Code
uniform sampler2D textureMap : register(S0);
float4 color = tex2D(textureMap,uv);
//New code
TORQUE_UNIFORM_SAMPLER2D(textureMap,0);
float4 color = TORQUE_TEX2D( textureMap, uv);


Pixel Shader targets:

Code: Select all

//Old code
COLORn
//New code
TORQUE_TARGETn


Semantics (vertex shader output and pixel shader input only. Vertex shader input remains the same as does all other semantic names)

Code: Select all

//Old code
POSITION
//New code
TORQUE_POSITION


There are a few other things so just ask if you have troubles with any shader conversions.

Timmy - Nice, thanks. Will be converting a class I based off of ScatterSky soon, and if I run into trouble I'll post about it. The class did pass some new shader values around.

Also just beware when using custom shaders, with DX11 it is very, very fussy that the vertex format matches exactly the same as the shader.

E.G

Bad (AppData in the vertex shader doesn't match vertex format):

Code: Select all

//C++
 GFXVertexBufferHandle<GFXVertexPCT> verts;
 
// Vertex Shader
 
struct Appdata
{
   float3 position   : POSITION;
   float4 color      : COLOR;
};
 


Bad(order is incorrect in the vert shader:

Code: Select all

//C++
 GFXVertexBufferHandle<GFXVertexPCT> verts;
 
 //Vertex Shader
 
struct Appdata
{
   float3 position   : POSITION;
   float2 texCoord   : TEXCOORD0;
   float4 color      : COLOR;
};


Good:

Code: Select all

//C++
 GFXVertexBufferHandle<GFXVertexPCT> verts;
 
 //Vertex Shader
 
struct Appdata
{
   float3 position   : POSITION;
   float4 color      : COLOR;
   float2 texCoord   : TEXCOORD0;
};
