    Hello
    I want to pass an HDR color through the vertex color. Eventually i want to set it as the Emissive color in shadergraph. Is this possible?

    Thanks!

    No but yes. The vertex color channel doesn't have enough precision to store HDR color data. However, you might be able to pack HDR color data into the second and third UV channels and then unpack that data in the shader.
