Shaders, how to make them?

[DrenDran]

seems like a real cool feature after I saw megascience's lsd one

I opened the code and it looks like you edit files in the shader directory, mostly the renderVsm_vert.glsl one which contains:

Code: [Select]

void main()
{
// Bricks always in world space.
  worldPos = (obj2World * vec4(gl_Vertex.xyz, 1.0f)).xyz;
  worldNormal = ((obj2World * vec4(gl_Normal.xyz, 0.0f)).xyz);

  if(length(gl_Normal.xyz) < 1.1f)
  worldNormal.xyz = normalize(worldNormal.xyz);

// Do some camera delta math.
viewDelta.xyz = worldPos - camPos;
viewDelta.w   = length(viewDelta.xyz);
viewDelta.xyz = -normalize(viewDelta.xyz);

// Fog can be done per-vertex.
fogCoords.x = clamp((fogConsts.y - viewDelta.w) * fogConsts.x, 0.0f, 1.0f);
fogCoords.y = clamp((worldPos.z - fogConsts.z) * fogConsts.w, 0.0f, 1.0f);

  // Project the brick pos and normal.
vPos = world2Cam * vec4(worldPos, 1.0f);
gl_Position = gl_ProjectionMatrix * vPos;
normal = worldNormal;

// Pass color through.
gl_FrontColor = gl_Color;

// Pass texcoords through.
texCoord = gl_MultiTexCoord0.st;
}

But if you're modifying one file, what if you have two shaders?
What am I missing?
Is there a guide somewhere I missed? (not stickied here, I know that)

Right now, there's no official support for custom shaders. You'll have to edit the existing files, renderCsm_vert, renderCsm_frag, and common to get custom shaders.

[Port]

Also note that you'll have to use a custom launcher, use an add-on that writes them on startup or set them as read-only for it to work; the launcher will automatically overwrite your changes.

The shaders reload when you change your shader quality, so you could just do optionsDlg.setShaderQuality($pref::shaderQuality);. Add-ons are loaded after the launcher runs anyways so you don't need to do that if your shader doesn't need a toggle option.

You can start up blockland, save your shaders and change your shader quality to see them.

I wouldn't want to manually update my shader files every time I start Blockland.

You could have an add-on automatically do that, like Tammy's bright point light fix, or make them togglable, like my shaders.

... you don't need to do that ...

don't know how I missed that
