hello!
it's been a week since i'm stuck to the stage of adding and combing fur on my model, i'm not happy with the results and i'm starting to lose my mind :)
i'd like to achieve a quite realistic-fluffy look.
i'm working with eevee render engine and so far i noticed:
- (hair-hair shape type) strip instead of strand actually enables to show/render the parameters of the hair shape.
- (children-interpolated) i can set length and threshold to randomize a bit the length of the hair.
- (roughness-endpoint) another control to randomize hair (the rotation?).
- adding more particles settings can help achieve more realistic look (one for the short fur base layer, one for the longer fur layer).
so a first problem is that when i start adding hair through the particle edit mode, when i click on the spot, it doesn't grow hair on the spot but actually surrounds the radius, with the result of unwanted hair on different spots.
then i cannot quite understand how to comb hair correctly, i watched tutorials, read guides, but i always end up with messy spots, i usually start combing on ortographic first (left, right, down, up) and then in perspective.
i attach the render of the stage where i'm at.
if anyone can help me i'd really appreciate it.
thanks!
So unfortunately I can't tackle all your questions at the moment, but I can offer you a few insights from my own experiments in fur a few months back.
First off, those rogue hairs that keep poping up are likely child particles. Set to simple mode they will follow only the guide particle you've grown, set to iterpolated they'll try to blend between their neighbors. Here I faced a tradeoff. Setting a lower child radius gives you more control but it also starts making the number of guide hairs unmanageable. I found myself creating two different particle systems, one with a large radius for filling in big portions while having a second with a small radius to work around details like eyes. No doubt there are other solutions.
As for combing, I found any effort to do so in orthographic views is counter productive most of the time. Instead you have to treat the process much like sculpting and work solely in perspective and constantly check your work from multiple angles. It also helps to only grow a few hairs at a time, style them and then hide them from view so you dont comb them out of place. Using the 'interpolated' mode on the add particle tool will spawn a new guide hair that tries to follow its partners, much like a child hair would, and that can save you some effort.
Kent's tutorials on realistic long hair can be of some help for understanding all the tweaks and settings, though the UI is dated compared to 2.8 and they don't cover some of the newer features.
Hope I've been of some help!
