    In 2019.1 Shaders: Added support for BLENDWEIGHTS and BLENDINDICES semantics in vertex shaders.

    but how we can access to that data in vertex shader?

    i try do so:

    struct vertex
    {
    float4 vertex : POSITION; // The vertex position in model space.
    ...
    float4 weights : BLENDWEIGHT;
    float4 idx : BLENDINDICES;
    };

    but data is empty...
