      Hello everyone 🙂
      Im trying to shade unmeshed, cloned splines.
      I need to have some kind of selection/falloff to be able to drive a blend material and blending between shaders.
      The usual suspects (vertex map/fields, distance node) doesnt seem to work on plain splines.
      Any idea how to solve that?

        Hi RemoGambacciani,

        A blend along a Spline is not given as a spline rendering, AFAIK.

        I checked again to see if any Hair combination might do… but sorry, no luck.

        As in the other thread, a Sweep and Vertex-Color Tag are needed.

        Please add your request to render Spline Vertex maps here (Share Your Ideas):

          Thanks a lot @Dr-Sassi !
          Thats what I thought...too bad...sweeping is not an option since we are talking about thousands of splines/hair in my scene 😄
          I will request that....I'm sure im not the first one to ask for that 😃

            Thanks for the reply, RemoGambacchiani. 🙂

            Yes, this was even asked a few times during the "Ask The Trainer" live show.

            Anyway, please try to minimize the geometry and let Redshift tessellate the results, which might be faster…

            As an alternative, could a plane with a texture/alpha help here out?

            Cheers
