How to apply new hair system for selected faces

iam not seeing any vertex groups inside Object Data Properties ie Curve Settings. Like how in particle hair system, do we have vertex groups in new hair system…

can you please guide me…

Dunno what you’re really did by using curves.

How I would’ve done that: after making a vertex group, go to particles, create a particle system, switch from Emitter to Hair, scroll down, open Vertex Groups tab, in field called ‘Density’ choose that exact vertex group you have just created.

I don’t have much time to fully explain it to you, so here’s the screenshot:

Hope it helps you

I am trying to use New hair system which is based on UV mapping coordinates.
Not being able to find the vertex groups in the new hair system., will do using Particle Hair option only. Thank you very much.

Oh, sorry, haven’t heard of that before. My method above - is how I would’ve done that in my own case. BTW, using hair particles you can also comb your hair by switching to Particle Edit mode.

Here’s a good example of how to use it:

Use a painted mask created in Texture paint … White for where you want your hair curves to be generated…
