MR Hair... help please!

Shave and a Haircut will output hair geometry that will rendering with maya scenes without compositing.

Hey Deke:

Thanks for the info!

I'm looking towards using Joe's plugin for my current project, but need some feedback from anybody regarding rendering speed of 'Shave' for Maya 5.0(compared to 'Fur') either with 'MR' (is this the 'Linguini' implementation, BTW?) or standard Maya renderer, in a production/animation environment.

Will be using 'PURE' (ART's renderdrive)with this anticipated setup also....

I would recomend using Shave and haircut to be rendered with Renderman.
I did a few test in the studio and It seems to be alot faster than rendering with Maya default renderer or MR. The comparison is like 10 -20 min(Maya,MR) vs 50sec - 2 minutes (renderman).
It's bloody fast, but quality vise... it's very subjective because it looks really nice in maya def. and MR renderings. while in renderman it looks alot more physical to me.
So I guess it's really depends on personal flavour. And one more thing, when we convert Shave to rib output. Somehow when we get it rendered under renderman, we always have slight color offset compare to Maya def or MR.

BTW, renderman is not that expensive actually. U can try AIR or Aqsis.

hi kfc!
So well do I remember your Valentine painting (with the pink background) :) !

Your recommendation for export to RIB sounds just the ticket, and in fact I've been looking at the possibility of using 'AIR' by chance(price ratio to RenderMan) , but cannot find any reviews specifically for this purpose.

50 secs compared to 15 mins. sounds incredible, so tempting!
I'll be using the 'ART PURE' rendering system, so hopefully any rendering speed differences will be negligable.

As the effect I'm looking to achieve is very cartoony, the dynamics and clumping are of more importance to me than colour-offset; I'm sure this can be tweaked with a little to-ing and fro-ing :rolleyes:

Thanks for the info: certainly food for thought :)

Hey Atwooki.

:)
Thanks for remembering my artwork. I haven't got time to work on another piece. Because it's seems that everytime when I really start making a paiting. It could be another hard time that i'm going thru.

oh well... nvm about that.
Speaking of Rib rendered in AIR. I never tried that, I only tried it under RAT + prman.
The shave default setting for rib output is to RIcurve. So if u wanna get it to be rendered with AIR (if it doesn't support RIcurve) U can try to output rib in to geometry under shave global.

What i'm trying to do now with shave is to make long hair character. It's a really challenging task... I'm actually trying to use nurbs plane to transfere dynamics of hair to shave. let's hope it works. TEST AVI (http://optidigit.com/KFC/research/rachel/hairDyn.avi)

hi kfc:
Thanks for the reply. I'm looking towards a similar goal. although a lot more 'cartoony', both in characterisation and dynamics/anim.

Your test is looking very convincing atm, and I will be looking towards a similar workflow myself. I think the RICurves get rendered OK in 'AIR', but just have to wait on that one to see the quality....!

I've finally got some of my job done. Going to have time to work with shave on characters again.
I'll try to post some new test later once I've got any good result. Please show me urs too!
:)

I'd be happy to see some nice result from renderman.

Hi there kfc:
Previous to this thread, I was going thru' all kinds of anguish in my many attempts to get PFX up and running Re:

http://www.custom3d.co.uk/bits/edith.jpg

Left: Simplified version Right: Original Version(heavy!)

but came across flickering in animation and slow updates (probably due to injudicious use of dynamics, too many different strokes and too many control-curves :shrug:

However, in my current tests, and given that M5 is so much quicker to update (even at 100% display!) I might well go down this route...I do still need to punish the prog/my system with a few more tests before hand tho', but will post soon;
who knows: a friend of mine is saying that the 'PFX ----> Poly' conversion bears up pretty well also in near to cam shots... :wise:

Look forward to your results...Oh! and what with 'Mayaman on top of 'AIR' (see above) I think PrMan its a much better decision (Shave-wise)

maybe we could share diffrent results of rendering using diffrent ways
like examples of paint FX, shave and haircut, Fur and poly modelling hair , also rendered in MR maya or renderman

gogogo :)
show ur examples with rendertime and usage:cool:

[AniMo]

i make the start ;)

hair done with shave and haircut ( version1,older one )
render with maya athlon 1,2 Ghz
rendertime 35 mins :cry:
but i know newer versions it takes only about 2 mins so abit useless this example hehe

the hair itself is lookin nice though i think (for a 2 min setup )

P.S dont blame me bout the too white blond
i like the slutcolor :D
