I Tryed different ways but nothing happend.

Thanks

Hello Kissling,

Do you want to use a texture for the color of the V-Ray Fur? If that is the case, simply create a V-Ray Material, add the texture to the diffuse of that material and apply it to the V-Ray Fur. Please check the following video.

You can also use textures to control the length, thickness, direction, etc. of the fur. To do that you will need to plug the texture in the corresponding slot in the Textures tab of the V-Ray Fur attributes. Please check this screenshot.

You can find more information about V-Ray Fur here.

I hope this is of help.

Hello Alexandar,

Thanks for your reply.

As you can see in your video the texture is placed on the ground.
The grass straws itself stays white.
I wanna place a lawn-texture on every single grass straw!

regards Ronald

Hello Kissling,

The texture is applied to the fur, not to the plane. Please check this video, where I demonstrate that in Interactive rendering, by hiding the plane or the fur. Let me know if that helps.

Hi,

Just to ask here as it's the same subject, I've tried looking at creating a messy long haired rug. How do you create a normal map to push the hairs randomly around and how do you use it with Vray5? Are there any tips to making this easily without much knowledge of normal maps? The attached is a piece of one from evermotion

Thanks,
Mark

Hello markTAVF,

You can drive the length of the hairs by plugging a texture in the Length texture slot in the Textures tab of the V-Ray Fur. Usually, that would be a grayscale texture where black is a multiplier of 0.0 and white is a multiplier of 1.0. You can find more information about the textures of the V-Ray Fur here. I hope this is of help.

Hi aleksandar.kasabov ,

Thanks for your reply. That pages is really useful, thanks.
If I'd like to create something like the attachment (from the help page) using normal style maps, how do I create the normal maps to get it working? Is there a quick way of creating random directional maps to any size using Vray at all?

Any advice is much appreciated

Kindest regards,
Mark

Hi markTAVF ,
have you tried using that texture as a Initial Direction texture?
Afterwards it's a matter of tweaking the general parameters - length, taper etc.
Here are a couple of quick tests with the same texture

Hi YunalZobu

Thanks, yes I tested the Evermotion texture and it does work well. I'm really interested in understanding how to create the texture to power the random look of a long hair rug, and if there is something out there that can create that normal map? I've looked for a while and wondered how Evermotion actually made the texture...unless it was painstakingly painting it by hand?

Thanks,
Mark

Hello,
its's me again.

It seems to me that my englisch is too bad!

Nearly everything you wrote is known to me.
(Before I poste here a question I read the manual and to some tests)

What I wanne achive is to place a blade-texture on every blade in the way like this:




But in the way discribed I only get this result:



Do I have use Mograph or Hair for this or is it possibel to use V-Ray Fur for this?

I've found a "tutoreal" here:

But there is not shown how to get this result:

Hello Kissling,

At the moment a texture can only be mapped along the surface of the V-Ray fur and not along the strand. This will be possible once we introduce the "Hair and Fur sampler". This is already on our to-do list (it is also listed here) and I will let you know once we have any updates on the matter.

I have a similar question, how is posible do this gradient color in fur?:


All my results are kind of weird in vray5:

[aleksandar.kasabov]

Hello ele_efe,

I apologize for the delayed reply.

You can add a gradient shader to the diffuse of a V-Ray Material, then apply it to the V-Ray Fur and set the projection to "flat", then you can adjust the projection accordingly. I created a simple test scene you can check. Let me know if that is of help.

aleksandar.kasabov, Thank You! reaaly thank you for your time

Hello all,

I am glad to inform you that last week we released V-Ray 6 for Cinema 4D beta and with it, we introduced the VRayHairSampler shader. You can use it with the V-Ray Hair Next material to colorize the fur along the strand. I hope this is of help.
