fur and scale

laverdet_943f1f7da1

Hello!!! I usually import my characters from zbrush... as they are a lot of "subtools", they are imported with "autoposition"unchecked, and disable scaling checked... ok, they arrive in carrara8 very small, but I don't care, I group and resize... fine...
BUT, it' seems a problem, when applying fur... I mean, I have to select very small length, like 0,002, and it's not at all so fine, like applying fur on a carrara sphere, for example... it doesn't change, if I resize to get bigger, much bigger objects, the Relationship to the fur is always "sick"... possible, but not so fine... somebody has already see that? and solve it??? thank you!!!

I can't help you at all but I did investigate at one time getting ZBrush. They don't use vertex modelling and I wanted to know if it would work bringing models into Carrara....sooooo, I found this product.

http://www.daz3d.com/goz-for-carrara It's $42 if you have Platinum Club, otherwise it's $60.

But I don't know if it will help your application of fur/hair in Carrara once you import your model. I don't know anything about it other than what it shows in the video which I DID LIKE.

I will be interested to know if someone here does have both products. I use a LOT of hair. I also love the extra sculpting tools in ZBrush and that GoZ let's you import and export between Carrara and ZBrush and have morphs, too! I have a hard time in Carrara getting my Neanderthal people to look properly Neanderthal without getting all sci-fi / fantasy.

So am waiting to see what any experts here can advise. It might make it worthwhile for me afterall.

:roll: Scratching head here..... xx Silene

ETA: I've had no lucking using Hexagon/Carrara exchange.... morphs all go to h*ll.

HI Celmar :)

When you talk about Fur,. do you mean Z-brush "Fibermesh" ?

If you mean applying Carrara dynamic hair to an imported Z-brush tool / sub-tool,.. then size may matter.

When you import the models from Z-Brush ,. set the Scale to 100% in the Assembly room, "motion" panel,
then select the model and either
edit in the Vertex modeller,.... or (if you're scaling to fit to a figure)
use the "Edit in assembly room" feature, to adjust the "REAL" scale of the model.

The Assembly room scale is a false scale, it doesn't change the size of the original model.
the vertex modeller is Real scale, it will change the size of the model.

Hope it helps :)

Hi Andy, Is the GoZ for Carrara any good then for anything to do with Carrara? :roll: Silene

HI Silene :)

yes,. but only if you have Z-Brush ..LOL

GOZ is a plugin that transfers models and textures between Z-Brush and whatever 3D program you're using,.
DS also has a GOZ,plugin.
There's also ZApplink which sends stuff back and forth between Photoshop (CS4 and above) and Z-brush.
much like the DS Bridge to photoshop.

In Carrara, you can create a simple model, then click GOZ, to send it to Z-Brush, where you can sculpt and texture, UVmap etc,..
then, you'd hit GOZ in Z-Brush, to send the model back, on it's own, or with all the Texture Normal Displacement maps, ..back to Carrara.

so, it's saving you the time in Exporting / Importing between programs

Carrara, can also do displacement painting (in the vertex modeller). using alpha brushes, which can allow you to do some simple sculpting and detailing, and it can do 3D texture painting, although,.. Z-brush is in a different class with a whole bunch of really clever sculpting and texturing tools.

3D-Coat is also a very cool sculpting and texturing program, very much like Z-brush

If you don't have it already,. you should download Sculptris, from the Pixologic site, It's FREE, and fun to sculpt and texture models then export those models and maps to load into carrara.

Hope it helps :)

What is your scene magnitude?

laverdet_943f1f7da1

thank you!! I understand effectively that the scale in assembly room is a false one... The problem is that I import from zbrush several subtools, which are linked to each other...So, if I resize, it's only a group, once everything imported... and as you saiy, re scale a group in assembly room doesn't change anything: the fur (carrara one, not fibermesh) is incredibly small (0,002), and difficult to comb... !!

HI Celmar :)

thanks for clarifying that it's Carrara hair,. not Z-Brush fibermesh.

The next question is,... What's the density of your mesh,..?

I'm thinking that if the problem isn't the scale of the models,. then it's possible the density / "Size" of the polygons,
As Evilproducer mentioned, scene scale could also be an issue.

I've had some procedural shading issues in the past when I create a vertex model in a large scale scene, then import the model (without re-sizing) into a medium scale scene, and then create similarly sized objects in the medium scene. Using the same parameters in a noise shader, or terrain shader function will give me very different effects on the vertex model created in the large scene from the similar sized model created in the medium scene for some reason. I was just wondering if could be doing the same thing to the hair.
