Does the shader compiler auto pack float/int properties into vectors?

    Hi all, was looking through some compiled HLSL shaders and it looks like float/int properties in ShaderLab are automatically packed into vectors. Is this true? Using Unity 5.6.0f3, only care about DirectX platforms.

    TNKS!

    That is indeed what happens.

    Thanks for the confirmation! I've only recently started looking at Unity's shader compile output so wasn't confident of my assessment.
