Hair And Fur Shader from trello

Development Rendering

Hello, can someone give a hint what exactly is this Hair And Fur shader? https://trello/c/IlsnH7Yl/25-hair-fur-shading

I’m really interested what ue4 team was able to achive with this and also when it will be available for community :slight_smile: Mayby in UE 4.10?

Interesting! If it was available in 4.10 I would expect to have heard more about it. Usually anything that gets “worked on” in Trello comes out like 2 or 3 releases later.

That sound really interesting. Hopefully it will also include “interaction effects” like the hair from nvidia (so not just a hair rendering shading mode) :slight_smile:

I’m guessing this could be that hair shader in action since it says in-game playable character?

I hope it will be the case. Hair in unreal is a real problem for realistic rendering.
So I hope we will have a good new shader + the hair transparency sorting ( dithered alpha testing don’t look good enough ), I’m sure Epic will provide to the community a nice result as always.

I see a new Hair Shading Model, Eye Shading Model and Cloth shading Model, but I dont see anything in regards to hair alpha sorting, or any kind of tessellated rendering or anything, so I suspect its just a shading model for now.

Tesselation is there already.

TressFX or HairWorks is way to go if you need fancy hair.

I understand that, but was verifying for people out there who might have thought the hair and fur trello card may have meant a similar rendering technique to HairWorks/TressFX built into UE4.

@: Where do you see a new eye shading model? The eyes of the character are completely in shade.

In the master branch as part of this commit: https://github/EpicGames/UnrealEngine/commit/fc669c6fc4dfa849af069eed69c7c991e3bc5869 look at ShadingModels.usf for the function EyeShading for the details.

Oh I see, thought you meant the teaser. My bad :wink:
