Fur with xGen and Fur Shade


#1

Hi Fellows,

I´m trying to make a caracter with fur, bunny like, and I testing the xGen approach.

. First I´d like to know if that tool replace nHair, if no what´s the better choice in maya 2015 or 2016;

. Also, I´m doing some tests with shades. Anyone has some tip to get a white fur without pulling gamma? Or we can do it just on the shade and not on the final render? Those are the first tests I get, the last one with gama correction of 4.0:

Any tip will be great.
Thanks!

Hi orozimbo
Xgen is a great plugin for feathers, hairs and fur. If it replace nHairs depends on what you want to do because for still images you don’t need nHairs. However if you want a simulated hair system the best way to do this is to take your Xgen hair system and add a clump modifier with guide curves, which can be driven by a nhair system and gives great results. Doing so you can also use the Maya force tools like gravity, air and so on.
I never used Maya 2016 but i heard from other forums that it is very instable and there are still some bugs. In comparison Maya 2015 is still the best choice, in my opinion, until bugs will be fixed in 2016. But i think they will work in the same way.
For a white fur, maybe it can be caused by a weak illumination. You can try a stronger light.
If not, I am using Arnold usually, and there you can adjust the ambient illumination strength and also for the indirect. In this way you can achieve a lighter hair shader and also a nicer withe.
If you tell me which renderer do you using, maybe I can try to help you.
In most render engines there is the possibility to tweak the light influence in diffuse and specular independently for each shader. Maybe try something like that.
I hope it could help you
Now just have some fun with this powerful feature. :thumbsup:
There are some tutorial on youtube just check them.
For other questions just replay on this thread :wavey:

Problem is mostly the hair casting dark shadows. You’ll have to plug a mib_shadow_transparency into the shading group’s mi Shadow Shader and set it to almost whtie
Tthis is for mental ray, if you use Arnold it might be something similar

Thanks Manuel, I´ll try xGen a little more. About the shade, I need to keep light setup and posproduction simple. Raise the power of the lights it´s not the solution for this project. In this case I would have to make light links or multiples render layers.

Great oddForce! I made a big improve with this tip.

The change in shader made the difference, but it still has a dark area. I put a directional light parented to the camera, so I don´t know what produces this dark areas.

Any idea?
