Hair and Fur WorkFlow 3dsMax

Hi!
Someone knows the right workflow to get the fur

Bump.

I also have a project with hair+fur in vray, so any answers are 2x appreciated

Any explanations or links to videos would be great. I have already done all the modelling, brushing, etc. and would just like to know the optimal way to render it render time-wise. The thing is, the fur is applied to a meshsmooth surface and the vertices transformation takes ~6 mins to calculate (after that the render is 30 secs). is there a way to pre-render these things?

Sorry if this question hijacked your thread. I didn't think it would be smart to start another thread, since this I think is also part of your question.

If you have any more specific questions, maybe I could also help you out.

cheers

Hi D365, realy no problem, its good to know im not lone with this problem rsrsrs...

Look,.. the best result that i got rendering all(model + fur) on scanline,
But Have some problem like feathers I will use with opacity,
and the shadow map 3ds dont work with opacity.

So Im realy wanted to render the model with vray, if was to redenr all with vray i liked more yet, But I dont know how to do this.

Trying render all with vray, after web search i got this:

- change primary bounces to light cache,
- turn on the retrace trheshold check box,
- secondary bounces to brute force,
- use vRaymtlHair, put the color map inside your diffuse channel
- chaange the hair amd fur effects render to mr prim
- turn on and put the vraymtlhair in "aply mrshader" on hair and fur.
- said me with out Ambient occlusion its faste but i wanted with AO

So, I done all this but the fur still thick, with out "Tip fade" on material fur modifier.
And with " tip fade " On, the render take to much.


So, for now I am thinking the best way is render the model with vray,
and the fur by buffer with scanline,
But the shadow game composite yet not clear to me.


D365, hope these help some.
Here my model with subdivision the fur coplained too, but rendered,
in 720p with a little space fur all on vray takes 6 minutes of frame render.

If you have some information more please post here.


And if some good Soul! to know how the best way to do this,(link, tuto, explanation ),
please give a hand.


Best Regards!

Have you tried lowering the hair count and increasing the root thickness and adding splay values?
Also, in Vray switch brute force to primary and light cache to secondary. You can also set the 'geometry shadows' to zero in the modifier.

Personally, I think the buffer effect looks too soft and 'painterly'.

shouldn't be the other way around? primary bounces to bruteforce, secondary bounces to lightCache...?

I agree with Meta.

Uou, sorry Guys
I had changed the words,

In vray render image I used:
Primary with brute force
ans secondary bounces with Light cache
And in light cache I had checked the Retrace threshold.

But the fur was very thick.

If some one knows the right way...


sorry my confuse english



Musashidan, Thanks!
I tried what you said, but take a similar results,
this way in vray I dont got a thin results to fur.




Best Regards!

Are you growing the hair straight from your turbosmoothed mesh or from a lower poly proxy mesh?

Hi musashidan,
Im hair with subdivision model, why?



Im thinking in render with several passes
- the original model with vray
- Only the fur without shadows, and with all fake light On.
-Only The Direct shadows from fur and only the direct shadow fro model to subtract one of other

- Only the fake occlusion shadow from shadow fur to ever have this on composite.

And composite all this to see if give alright,
I will try this if are ok I post here.


Thank everyone, and if someone more here knows the right way to do this,
please post here.


Regards!
