VRayFur Carpet Tutorial

Alright! I think it passed long time since I actually wrote a tutorial, with examples and FREE 3D Models for Download -such as VRayFur Carpet  that was made with3Ds Max and VRay.

Here’s the carpet that I was working on during my last project, and the difference between this one and many other tutorials on the net, that this one actually teaches you how to use Maps in order to give style and natural look to your VRayFur Carpet.

Step 1: Apply VRayFur to object with one surface, such as “plane”.

Note: Box might not be advisable for carpets – it will grow hairs on both sides of the box.
If you have modeling skills you can model a nice carpet shape. Just pay attention to your segments if you gonna use “per area” function.

Tweak these till you satisfied with the length, thickness, bend, gravity and tapper . The Variation parameters (Direction var, Length var…etc.) – will provide you with random differences between the hairs, direction, length, thickness and gravity – “0″ meant no change and “1″ full change. Those adjustment will go faster if you will work with “region” render tool – to render parts and compare the change to previous one.

It works good on “Long shots” but if you are doing “Closeups” you need to increase “detail” by changing the amount of hair “per area”.

Looks good! That’s it for tutorial, you can do carpets.

Wait we’re not done yet!  Now, to the stylistic part!

First thing first – and we have to give texture to the carpet, as simple as it gets!

The reason for giving light gray at one end than the other -  is to make “roots” darker than the “tips”. That leads to interesting colorization options – explore colors of your true nature!

Note: Make sure that you have WU mapping turned on -  otherwise you will not get proper mapping to your hair.

Step 2: Let’s “Brush” our hair!
We use colors to give direction to hair distribution – most likely that been made according to the color wheel.

All depends on your camera location, but general contribution will be up/down (north/south) -> Red/Green. As these colors opposite to each other you might get collision between hairs.

Make sure who’s up and who’s down 

My suggestion to you, is to make a test render of colors, that way you will know how to colorize your map.

Ok – Now lets see what channels do we have for our maps!

The first 2 maps work on the color mode – RGB , other maps on black & white – MONO maps…that’s it have fun with it!

Just kidding  Here’s what I used for the bending direction – now I know it’s not fancy looking piece but I just went with colors and this is what gave my Furry Hair direction.

Note: I use these maps as an edition to what we did in Step 1 – Length, Thickness and Gravity I’m not going to change, however the direction will be stylistically added with the help of:

VRayFur direction map

Looks weird ha – I know it’s not Picasso, but look at the green cube and circle…well it’s for the reason! These guys actually preventing from my hair go through the model surface.  That way we get “Hair FREE” models.

To produce same map – use top view for print-screen (match map) – if it’s not the fastest then it’s the easiest way to do it.

VRayFur Initial direction map got pink and purple noise map – remember that direction of bending controlled here by the color palette, so “warm” colors will have one direction and “cold” the other.

VRayFur Bend map will help you to get that harry natural curve – noise map can control nicely that task.  You can keep playing with other maps and get maps for length, thickness, gravity and density and see where it takes your hair.

The rest I’ll leave to your creativity – Send me your awesome results of carpets AND the good ones I’ll post here 

Share this post and hopefully it will reach to a lot of VRay users that still do not use maps in their carpets! Let “carpets” look like – “THE Carpets”.
Happy testing!
