What is the ETA on exhaustive official documentation on the hair material’s specifics and best practices (model and texture) for achieving Paragon-grade results? The content example material isn’t sufficient enough for genuinely understanding how to work with it for the best visual outcome. I could see in the hair feature preview video that the Backlit feature, which has been assumed broken, was being used with some kind of a specific parameter configuration beyond just plugging in a Scalar value, for example. Since the material is really performance heavy, it would be great to know how to make the most bang for our buck with it.
I also really need to know if there is a specific map lighting or model setting configuration needed to get the proper shadow mapping showcased in the preview videos. Copying the sample material only got me vague indistinct shadows and barely any self-shadowing or occlusion at all, total lack of a sense of depth and volume. Additionally, pixel depth offset seems to just mess up my hair model and expose the bald scalp underneath even with low values instead of creating the organic hair card intersections advertised.
I unfortunately can’t share screenshots or assets because of NDA.
I can see that the Paragon hair cards are using averaged vertex normals (as opposed to smoothing the normals across cards with a normal steal from a blob mesh) and the material seems to blend away the card edge transitions for a smooth, soft look. I can’t find a solution for getting this effect even when I’m layering a lot of flyaway cards over my main cards to try and blend them out - the lighting exposes the card geometry no matter what I do. How was this effect achieved in the mesh, material and/or lighting?
