It is mentioned here that you can add custom attributes yourself Can you tell me where these attributes are added On the curve? https://docs.unrealengine.com/en-US/...nce/index.html

I would like to know too.
Also i cant apply materials on the hair itself. Don't know what im missing :\ And applying niagra dynamic to hair seems off. I mean shading looks different.
I attached screenshot. Right side is not applied and left side is niagra apllied.


--------------------
okay i figured it out. turns out. In material editor you had to check used with hair strands. and there's a node called hair atrributes in material editor. So then you can use your attributes.

Gandosh, were you able to figure out the groom_group_ids? Would you mind posting a bit about your process?

I've been trying to get the Hair Shader in Unreal to behave the same way that aiStandardHair does in Maya, but haven't had any luck with texture maps. In Arnold, plugging in color maps is very straight forward, and the hair picks up the color of the textured geo:

I've been trying a similar process within Unreal, and I'm definitely missing something because RootUVs and BaseColor don't seem to be working:


Unfortunately, even though the docs cover other areas (like root and tip color), nothing is mentioned about this specific process. Any help would be much appreciated!

我也没搞明白 abc 为什么要带 自定义属性，这个插件如果像hair works 可以用贴图转成灰度图，控制粗细 密度 noise 等属性就好了，现在是beta 版本 短毛的角色和动物 可以勉勉强强使用了 ，人物和角色 不建议 使用。
