    This means I'm going to have to use twice as many uv channels to pack in the data I need. Is there any way to get access to the other 2 vector components?

    (While we're talking about mesh sampling - I was really hoping to be able to randomly sample anywhere on the triangle. Without any index information this is impossible. Compared to point cache baking this feature feels little half-baked.

    Looks like I'm going to have to go back to packing my data into Texture2D...)

    Hello,
    We are aware of these limitations and it will be substantially improved with the Skinned Mesh Sampling feature which we expect to land soon.
    This feature will not only add the support of sampling vertices among skinned mesh but also add topology (to sample anywhere on the triangle) and TexCoord fetches up to the fourth dimension.
    Additionally, the vertex color format is limited to a Color32 attribute for now, we will allow the sampling from a Color (Float32).
