Hair from Mesh Strips Questions

Hi. I think I have a pretty simple question. I'm making hair from the Hair To mesh strips node. I use the last mode, it does a great job of repeating all the Mesh hair shapes, but there is one downside that I don't know how to solve. The hair turns out as if it is "Clumped" . How can I make it look natural? That is, that would be "each hair is separate.

Hi,

Can you show me a screenshot of what you have compared to what you expect? 

Hair from Mesh Strips will generate hairs from the polygon strips provided, so the hair will follow that exact shape. I think that is what you mean that it looks clumped. 

I think what you need is hair interpolation. If you really need or want to use Hairs from Mesh Strips, then you can combine it with the hair interpolation workflow.

THIS video explains the process. It is for Cinema 4D but you can follow the same steps in Maya. Let me know if you have questions about any part of the process.

Yes, all the hair looks sticky. It looks horrible, not like a full hairstyle, but like everything is glued on) I think you get the idea. I don't know how to deal with it.

That is howq Hair from Mesh Strips work. The hair is based on the provided strip shape. 

The video linked here provides a more expande workflow.

Hi! I am still experiencing problems. I'm trying to do GroundStrands, but my hair just flies off in different directions. It's like they got electrocuted)

As much as I've tried, this is the maximum I can get. For some reason everything happens in a horrible way.

This is the hair I want to do (mesh) https://www.dropbox.com/s/27e31pg8v85m80p/oneida.obj?dl=0

Before creating the hair, make sure to delete the history and freeze the transformations of the objects that you will be using for the hair generation(The mesh strips and the scalp where you are going to ground the strands). This is so Ground Strands works correctly.

I don't understand what I'm doing wrong. Repeat exactly as in the video you sent + I deleted the history and froze all the transforms after putting the hair in the right position for me (Mesh) . Next I added HairFromMeshStrips, then GroundStrands, HairFromGuides. The hair flies in different directions and even if I manage to "calm it down" at least a little It doesn't follow the shape of the hair anyway.

I got something, and at random, but it is not much different from the result that was. + I can't multiply the hair, I have to use MultiplyStrands node, and it doesn't just multiply the hair, it's the root as you know... that pretty much kills the rest of the shape.

Please help me figure this out. I've been trying to figure out what I'm doing wrong for quite some time now. And writing on the forum was an extreme decision. I seem to do everything according to the instructions, but I always get the same result. You can see the bad quality of the hair and how stiff it is, as if it was just cut off. In terms of thickness, it's 0.005 and the Ramp is smooth. I also use Multiply to get more hair.

P.S. Rendering production quality in 4k.

Sorry for the delay. 

It sounds like you are following the steps correctly but for some reason is not working for you.

I suspect there is something with your mesh that I didn´t consider. Can you provide the scene for testing?

Yes, I thought it might be a problem with the mesh, because I remove the Scalp layer and attach the hair directly to the head. I also have a question... I've done hair in Xgen before and it always looks great. Ornatrix hair looks different, more "plastic" why? Maybe there is some other setting. I especially see a difference in the thickness of the hair. The roots are particularly thick no matter how I try. My head is either bald or my hair is thick:)

I'm not sure if I understand the hair thickness issue. have you tried the ramp curve in the Change Width node to set the strand width along the strands?
