Hi,
I am building a studio with XSI as the main software in the pipeline.
I will be working on animation and VFX.
So here is the problem:
XSI hair is not the best! ( and somtime it's a paint)

So I thought C4D is cool since I will include Body paint 3d in the pipeline, what is the most efficient way to transfer character rig and animation form XSI to C4d do the hair sim render the hair in C4D.do the compositing later.


Any efficient possible solution will be appreciated.
Regards

I heard some people can export hair via nurbs curves but if i am reminding correctly C4D doesnt have nurbs but could have some solution with splines.
.Obj should be the first format to try.
There are one or two frequenters in this xsi forum here that know C4D they will probably know better.

Hey man ... what's wrong with XSI Hair ?????

IMHO : XSI Hair is one from the best Hair solution in the market , but if you know how to optimized on rendering .

Example: See this article for Film call : The Brothers Grimm .. all the hair was done by xsi ) :

I'm trying to get away with the easiest and most efficient pipeline.
C4d hair is ready out of the box.

I do not like to concentrate my everyday effort challenging the software.
in my case XSI gives me every thing easy and ready to use except hair. it is a bit of a hassle to optimise.

"Most of the work on it was done with XSI, and rendered with Mental Ray. We had a full-time specialist from Mental Images working with us to get the fur right"

this is a quote from the article you gave me a link to......you see I don't have the luxury to have a full-time specialist from Mental Images to work with me. :D

even though we cant avoid mixed pipeline anyway right? :)

Don't forget ..The example that i gave you is for the film .. in the films the quality must be very very realistic .. and there are a lot of time to rendering cuz this long movie ...

anyway .. that is my opinion .. i don't want to change your thread direction ..

I hear C4D reads Lwo and mdd files,.. XSI exports Lwo and Mdd files

so you can by how i read it in threads and features list
C4D would work like Lightwave and Messiah by using mdd files to transfer the animated point deformation,. then in C4D you add you hair to the LWO and add the Animation to the same model using Mdd.

But i would try Bhairy for XSI before you setup and pipeline like that.

XSI ADV simply costs too much and you get so little compaired to ESS
Crowds, hair and cloth and 2 extra Mental ray nodes,.. it's just not worth it.. :hmm:

give me 6 Mental Ray nodes and Face robot and I may update :D

$80 for XSI any version :thumbsup:
not as good in the styling controls as FUll XSI hair But it's getting there

this is cool.
does it support animation, I mean dynamic interaction!!

With mdd, your exporting Point animation NOT rig animation

So in other words Mdd save the Mesh deformation and only mesh deformation that is created by the XSI rig.

you can export nulls and rebuild/transfer rig data tho that would be a major job i feel ....
( xsi 6 has a whole new level of this tech i think but related to Max and maya how i read it )

All you need to transfer is the model geometry and animation... and camera animation. Then setup your hair in C4D, render and comp over your XSI renders.

There are a few scripts on xsibase for exporting/importing camera animation to some applications but I'm not sure if C4D is one of those. Check them out though. Also look into FBX and pointoven (if importers exist for C4D).

Sorry I have zero experience with Cinema4D but the same tehniques apply. Maybe look into Maya for hair. It's a little more supported as far as I/O goes.

I spent a bit of R&D time looking into integrating C4D and XSI passes about 2 years ago... I was pretty disapointed to find that matching the camera was not accurate enough for my needs. I did several tests involving basic primitives with constant shaders and found getting a better than 99% match was nigh-impossible. Aliasing differences and slight perspective disparity were the primary issues... I'm sure with more time I could have gotten it there though, but I went to an all XSI pipeline instead.

really what is the alternatives to XSI hair .

of course you can tell that it is expensive, so as maya Unlimited hair.



that will leave me with ........say max does it have a really good hair system?
