I’m not sure if I understand your question exactly @TrygonLudo , but:
Thickness, ie how many hairs there are is based on the tiling of the opacity/fur texture mask in the material.
The amount of polygons used in the growth mesh determines how heavy it is to render, and how polygonal the silhouette is.
So yes, you could have a lot of hairs on either a low or high poly model. (Though the smaller/finer the fur, the more affected it is by resolution and quality-reduction over distance.)
Tiling at: 1x, 0.5x, 0.25x, 0.125x: (Same mesh/material, same amount of polys, only adjusted tiling.)
The polygon shell itself mostly functions as the canvas for the fur material to be rendered on, so high/low polygon counts don’t have a huge impact visually.
However, if the polygon count is really low, it makes the silhouette of the fur very blocky, just like if you saw the actual LOD up close.
Mannequin LOD at, 0, 1, 2, 4: (LOD4 is only 1231 tris.)
You can see how the fur itself doesn’t change much, despite going from 41k to 1k tris.
By the way, [USER=“262180”]GiM s.r.o.[/USER] , I went ahead and bought it (really glad with how much better the quality is on things once it’s possible to groom them in-engine instead of passing them back and forth.)
I was just wondering about something:
Would it be possible to add a toggle/freeze function to the grooming tool?
With a character I’ve got 1 base, full-body fur, and then a smaller hero-fur for a mane (as an example.)
But the grooming tools groom any gfur they touch, would it be possible to have it exclude some gfur components in the scene, so that I can groom the hero-fur without it affecting the first, full-body fur?
Honestly, if it were possible to just add a freeze-tool, then that would solve this issue, and give a bit more flexibility to grooming in general.
(With the option to freeze an entire gfur component, or just paint specific areas to be frozen.)
(I solved this by just duplicating the character, and removing the body gfur from it, so that only the hero fur was present, then groomed it separately, but it would be nice to have all the fur present for visual feedback.)
I think i made a mistake, i installed gfur pro v2 and then installed gfur free version, now i don’t get gfur pro grooming tools xD is there a way to repair that ?
@ax448 Thank you very much for the information and sorry for late reply
I do have an other question : How is it possible to change the min screen size value to increase the distance of fur disappearance ?
Right now even with min screen size to 0.0, the fur disappears quickly when I get some distance between character and furry mesh. Which line/value in the plugin would allow the fur to remain visible with most details possible at greater distance ? (regardless of performances)
After a lot of testing it seems to be related with the morph targets, if i set morph target on my mesh in runtime it just crash.
if i don’t use it it works but if i use the node it just crash
i just bought the PRO version cause you guys said it had morph target support, and i’m not even using morph target on the growth mesh i’m applying it to the character mesh, funny that it worked fine on the free version to apply morph targets on the character mesh, if i knew i would have not bought the “PRO” version :/, can you please fix it?
https://drive.google.com/file/d/1ANa…-0-v8LJct/view GFur Pro unrealized I believe that this technology was created to implement physics with minimal cost. Interaction with the wind, correct handling of the displacement taking into account winds (there can be many sources, for example, fans), even this is not supported in the version that is silly called pro. It’s just the same gif 1 layer, you can make moving wool !!! What a shameful implementation!
[USER=“262180”]GiM s.r.o.[/USER] Heyo, I was just wondering, would it be possible to take a look at RT GI support? (Through Unreal’s built in RT.)
RT shadows behave pretty much as normal, and you need to use contact shadows to get in-fur shadows. That’s pretty much what I expect.
RT AO also behaves as you’d expect, and overlays properly, though it’s only based on the model’s geometry. Again, as expected.
But gFur doesn’t accept any light from RT Global Illumination. Which makes it darker and less directionally lit than other objects in the scene.
Is this something you could take a look at? Even just seeing if there’s a way to apply GI that hits the base model, to the fur, or something like it.
(Tested in u4.23)

Hi sorry but is there a gfur for dummies tutorial?
I am just a dumb DAZ and iClone user and I am totally lost cannot do advanced stuff
I basically want to just grow some hair on a skullcap but it seems to select the entire mesh and importing and adding the skull cap as a component to my player loses my player animation BP even if I use the same rigging, I never had any luck parenting stuff to third person players only “animated NPC’s” I drop in the scene
I render animated videos either retargeting a figure and then capturing it running through a scene from the editor in a standalone screen or by dropping FBX animated figures in the scene. I can attach a hair cap to the latter and if it is a skeletal mesh can in theory grow hairs on it, except I see no hairs only the orange highlight and cannot find that painting mode to grow it.
I tried growing hair on animated animals in scene too, no luck, don’t know where to find the tools shown in the video.
Hey [USER=“262180”]GiM s.r.o.[/USER] , now that Unreal is working on it’s internal hair rendering system, would it be possible to tweak your grooming tools so that they can alter/generate splines for the hair system?
You’re already generating splines from each vertex and manipulating them, right? If there was just a way to either:
A: Export/Save gFur groom as splines unreal can use for the hair rendering.
or even
B: The ability to use gFur grooming tools on the new Hair splines in-editor would be very useful.
If you can just export the groomed splines as an abc with the splines in, you could just have unreal reimport it as hair splines.
I imagine a lot of people would be willing to fork over some money to be able to groom characters in-editor, and Epic hasn’t mentioned any plans to add those tools themselves, as far as I’m aware.
Awesome, good luck.
And who knows, maybe you can tap into the whole niagara x splines setup they’re using for hair physics, and can use that for gFur as well, down the line.
