    Honest Standard Shader questions (Height Map)

    And my bad, the occlusion isn't being offset by the heightmap. That seems like a silly bug.

    Honest Standard Shader questions (Height Map)

    No, set your texture to "Advanced" and in the options, enable "Bypass sRGB Sampling".

    Honest Standard Shader questions (Height Map)

    The issue is that it offsets the UV coordinate depending on the height value and the viewing angle. Sharp transitions in the height map will cause...

    Change vertex colors with shader?

    I'd put together a shader with 2 keywords (BLENDING and WHITE), and 3 materials with it assigned. One material with no keywords (i.e. shows vertex...

    Setting the normal map scale (intensity) through code only works on editor, not in the build.

    I think it's only supported in shader model 3.0+

    GLSL arrays can't be size 1?

    It's possible that setFloat, when given a single value, is just calling the "single value" version of the API's "setFloat", rather than the array one.

    Why does smoothstep get "optimised" OpenGLES?

    I'm guessing for compatibility purposes?

    Knowledge required to write shaders?

    As BrightBit said, vector math is the main thing (dot products, matrices). You do also need to have some understanding of what's costly and...

    Generating new vertices in a shader

    Yes, you can't duplicate vertices in a standard vertex shader (I should have mentioned that) :P

    I Found a Problem With Metallic Rendering

    That's not wrong, I think you just misunderstand what PBR is and what's happening. At glancing angles, all surfaces will reflect a nearly all of...

    Generating new vertices in a shader

    Generally for this you don't duplicate the verts, you just draw the mesh in two passes. One draws the outline (pushed verts, inverted normals) and...

    Lerp Vertex position in Shader

    Try just lerping the xyz... the w component should remain 1 for matrix multiplication's sake. v.vertex.xyz = lerp(v.vertex.xyz,...

    Question about the Toksvig factor

    With the scale factor, you'll probably want to unpack the normal (*2-1), get the Toksvig factor, then scale the normal (to scale the normal,...

    Unity 5.3 GLCore (4.1), if statement shader compiler bug

    It might be that GL4 is more strict (like DX11). So you'd have to do color *= vec4(0.1);? Could be it's not picking up on those things yet.
