You can set the resolution of the mesh from the "Settings" panel.

Before you click to add the hair curve, on the top there is a "Curve Shape" drop-down menu. There you can set the Length.

@@denoa3D Thank you, for the quick answer, I found it.

Yes, if you add more curves you should expect some slowdown. I have tried to optimize the node tree as much as possible, but still, having a large node tree on every curve is going to tank the performance. Here are a couple tips on how you can avoid these issues: 1. If you have lots of hairs that are similar in shape, you can have them as a single Curves object. Simply add new hair curves with the Add brush in Sculpt mode. They will all share the same node tree, which is more lightweight than having them as separate objects with their own instance of the modifier. Of course, this will limit the editing ability, since they all have the same settings, but you can still change individual Thickness and Rotation from Edit mode with Alt S and Ctrl T. I usually do this on "filler" hair curves, that are not that key to the overall hair style. 2. If you have some hair curves that you know you are set with and not going to change them, you can convert them to mesh and this will remove their instance of the modifier. 3. Lowering the geometry resolution still helps with the performance. Also, having a low poly base mesh helps a lot. These are some thing you can try to improve your scene. I have more optimizations for the next update, that will hopefully help people with lower specs.

Yes, simply add a new mesh object, merge all its vertices with M, so that you have a single vertex, then extrude and snap it to your character.

You want the iris to be at the center of the flattened circular region, if I'm not mistaken. That would be very easy to set, you just have to rotate the whole eye with the squishing rotation: 1. If you pause the video at 58:44, get the first 'Vector Rotate' node (the left one) and duplicate it with its connections (Ctrl Shift D). 2. Check its 'Invert' checkbox. 3. Add a new 'Set Position' just before the other Set Position (in the video frame). 4. Plug the output of the copied Vector Rotate to the 'Position' input of the new Set Position. This will rotate the eye texture with the squishing rotation. You can add a Switch node, if you want to make a control out of it. Technically, it will be "cross-eyed" once you do that 😅, but I know what you mean, "visually". Though, if the angle of the squish is too great, the eye movement will start to look unnatural. In that case it's better to have separate eye objects, and maybe even separate target objects. Hope this was clear, let me know if it worked out.

@@denoa3D Wow, I really appreciate the speedy reply! This is close to what I want, but I was just hoping to rotate it slightly. This does indeed make it a little too cross-eyed in the other direction. Is there a way to control this more precisely?

Yes. Simply add a Mix Vector right after that new Vector Rotate and use a Position node for the second input of the Mix. That way you can control the amount of shift.

@@denoa3DThat's it! Amazing, thanks for the help!

Hi. That usually happens when the root of the hair changes its relative angle with the base, so the curve normal gets recalculated each time the hair moves, getting all wonky. I've accounted for that in latter versions, so make sure you use the latest version of the addon and rig the base mesh to a Bone, not with Armature Deform. Also, one thing might help is to increase the Effect Factor slider a bit higher, so it ignores the hair root. I can't really recreate that issue, so if these things don't help, send me an email with some more info so I can look into it.

@@denoa3D Thx for reply,I'l send you an email.

Hi, check the answer to the pinned comment, I think you have the same issue.

You can use the add-on on bezier or path curves as well. There you can edit them normally. Otherwise you can edit hair curves in edit mode with proportional editing on, but that is less useful than sculpting.

No, this uses the updates to geometry nodes past version 4.0

@@denoa3D How do I use that eddon in blender 3.4? I would appreciate it if you could attach the link.

Yeah, that's a part of Blender that is kinda annoying. Unfortunately, I don't know of any solution, apart from, as you said, set the falloff to Projected.

Kind of. If you convert the hairs into mesh and combine them in a single object, you can't bake the textures right away, because the combined mesh will have overlapping UV islands. If you try to bake, the last UV layer to be baked will override all the others. You really need to pack the UV islands before baking, but if you do, some of the textures that come from attributes will shift around, so you won't have the same effect. Here is a workaround you can try: 1. Create a high-poly copy of the hair curves, convert them and merge. 2. Bake any texture you want from the material to color attributes (create new ones for the bake, you can use Face Corner data for better resolution) 3. Pack the UV islands. 4. Now you can bake the color attribute to an Image Texture. You can get access to it in the shader with a 'Color Attribute' node. 5. Then you can use the Image Texture in the low-poly version of the hair. Obviously, this has some drawbacks, but the higher poly you have your burner mesh, the better the quality of the texture. You also have to pack the UV islands the same way in the high and low poly versions of the hair mesh. Hope this works out for you.

unfortunately the addon is crashing blender. not sure how to diagnose

simply changing the eyelash count crashed blender

i don't suppose you would make a simpler lightweight version?

Hey, that's weird, I can't recreate this issue. What Blender version are you using?

@@denoa3D 4.2

Check the mesh density of your base mesh. Try to make it as low poly as you can.

@@denoa3D its currently at 800 faces

For the demo character exactly, yes. The material really, is what you make of it. The shades from the addon will work on both render engines.

Yep, that is something I am working on!

Hi. You can't easily do that right now. I am working on stand collisions for the next update 🤗

​@@denoa3D oh, thank you for replying me. So I will wait for the next update :) when do you plan to release it?

I did it myself a couple years ago simply by trying some of these noises until it looked nice.

I can definitely do that. I was intending to do an update to the generated armatures to be a bit more useful. Just out of curiosity, what would be a good starting point for the armature chain - further up the hair strand or backwards, into the head of the character?

@@denoa3D especially in anime style models, the bones tend to begin lower down the hair. this can prevent bangs from moving too much, allow for ahoges to stay in place, or have the back of the head stay in place while the ends can move. i think the option to have it go all the way to the root is still good to have, for ponytails it would be essential. i dont know if moving it into the head would be useful, though.

Yep, definitely could do that in the update. If you want to do that now, you can just move the 'root' joint further up the hair strand while using Volume snapping.

That happens when you parent the hair curves or the base mesh to the rig with the Armature Deform. Instead, parent to the bone directly, through Pose Mode.

@@denoa3D Thank you so much, now it works perfectly!! Your addon is truly magical!! 👏
