| | Hi,
Is there any example on how i can create a grid texture (1x1) on the terrain? I do not want to replace the multitextured terrain.
If there is a better way to show a squared grid, please tell me. I'm desperate on this because i've been asking this on a whole lot of forums and there was no answer in almost 2 months now. :(
Thank you | |

| | I'm not sure if i understand it right but i think you want to draw a grid like most (3D modeling tools have)
If that is true you need to make the grid rom vertices and conenct them as triangles.

Maybe something like this? | |

| | Ohh i see what you mean. This amy have been obtained by modifieing the textures to have a black outline.
Or maybe from Pixel shader. If the Texccord X < 0.05 or bigger then 9.95 then you return black as a color. The same thing should be applied to the Y.
This should give you an outline to the texture without actualy modifieng it. | |

| | Thanks,
Do you have a sample code for me? I don't know how to apply that black color within the pixel shader while using multitextures
Pixel shader code:
MTPixelToFrame MultiTexturedPS(MTVertexToPixel PSIn)
{
MTPixelToFrame Output = (MTPixelToFrame)0;
float lightingFactor = 1;
if (xEnableLighting)
lightingFactor = saturate(saturate(dot(PSIn.Normal, PSIn.LightDirection)) + xAmbient);
float blendDistance = 0.99f;
float blendWidth = 0.005f;
float blendFactor = clamp((PSIn.Depth-blendDistance)/blendWidth, 0, 1);
float4 farColor;
farColor = tex2D(TextureSampler0, PSIn.TextureCoords)*PSIn.TextureWeights.x;
farColor += tex2D(TextureSampler1, PSIn.TextureCoords)*PSIn.TextureWeights.y;
farColor += tex2D(TextureSampler2, PSIn.TextureCoords)*PSIn.TextureWeights.z;
farColor += tex2D(TextureSampler3, PSIn.TextureCoords)*PSIn.TextureWeights.w;
float4 nearColor;
float2 nearTextureCoords = PSIn.TextureCoords*3;
nearColor = tex2D(TextureSampler0, nearTextureCoords)*PSIn.TextureWeights.x;
nearColor += tex2D(TextureSampler1, nearTextureCoords)*PSIn.TextureWeights.y;
nearColor += tex2D(TextureSampler2, nearTextureCoords)*PSIn.TextureWeights.z;
nearColor += tex2D(TextureSampler3, nearTextureCoords)*PSIn.TextureWeights.w;
Output.Color = lerp(nearColor, farColor, blendFactor);
Output.Color *= lightingFactor;
return Output;
}

Thank you! | |

| | After MTPixelToFrame Output = (MTPixelToFrame)0;
you add If(PSIn.TexCoords.X < 0.05 || PSIn.TexCoords.X > 0.95 || PSIn.TexCoords.Y <0.05 || TexCoords.Y > 0.95)
{
} | |

| | In the middle of that if Add return Output.
Thix should return black instead of the edges of the texture. Hope this is waht you need. | |
