<br />
<span style="font-size: 15px;"><br />
A lot of tutorials out there are talking about how to make grass with  3ds max and V-Ray. Some are very poor and some are absolutely crazy good  (see <a href="http://www.evermotion.org/vbulletin/showthread.php?t=73989" rel="external">link</a>)  with everything in between. There are different techniques to create  realistic grass including using displacement modifier / map, modeling  and instancing, using V-Ray proxies, etc...<br />
<br />
The deal here is to create grass on a flat ground, which is good looking  (and visually not repetitive), and not too heavy in the viewport /  renderer. All this with the minimum effort :)<br />
<br />
I tried a few techniques and figured out that for me (so maybe for you)  the most efficient way is using Vray proxies. It's a very powerful  feature of V-Ray (Mental Ray have it too): it's very memory (RAM)  efficient and render time (CPU) efficient, which are major advantages  when creating CG grass. Plus it's light in the viewport.<br />
<br />
So here is my simple and (in my sense) efficient work-flow:<br />
</span><br />
<div class="secondMenu">1: Modeling:</div><br />
<span style="font-size: 15px;"><br />
First of all you have to model or buy a square of grass.<br />
I have personally chosen  'Puzzle 12 AM63' from Evermotion (see <a href="http://www.evermotion.org/modelshop/show_product/puzzel-12-am63/2408/0/0/" rel="external">puzzel 12 AM63</a>) which for 15€ is a good time saver and delivers good results.<br />
</span><br />
<div class="secondMenu">2: Export V-Ray proxy:</div><br />
<span style="font-size: 15px;"><br />
You have to prepare this square of grass into a V-Ray proxy.<br />
Check the size, material, pivot point and whatever of your square of  grass, because it will be the foundation of all the next steps.<br />
I re-sized the square of grass for it to be 1 meter by 1 meter.<br />
I centered the pivot point at the basis of the grass and then placed the grass in the middle of the scene (coordinates 0,0,0).<br />
Now you can fine tune and test your grass material.<br />
Then to create a V-Ray proxy (.vrmesh file) you select your object and  right-click and then 'V-Ray mesh export'. No specific export option  required here.<br />
<br />
<img alt="" height="468" src="http://www.evermotion.org/files/tutorials_content/2-Export-V-Ray-proxy.gif" width="640" /><br />
</span><br />
<div class="secondMenu">3: Import V-Ray proxy:</div><br />
<span style="font-size: 15px;"><br />
Reset 3ds max to have a fresh scene.<br />
To import your V-Ray proxy (.vrmesh file) go to 'Create' then 'Geometry'  then 'VRay' then 'VRayProxy' then 'Browse' then find your .vrmesh file.<br />
Your grass model will be imported as a proxy into your scene. At this  point you need to change the display option of your proxy into 'Bounding  box' because it will be instanced hundred times and will kill your  computer if you leave the default 'Preview from file' display option.<br />
You have imported the mesh but not it's material so you have to import  the material separately. To do so, go to the Material Editor and then  'Get material' and then 'Mtl library' and then 'Open' and then choose  'File type = .max' and then find your .max file (the one with the grass  model and it's material ; the one of the step 2). Drag and drop the  material from the Material/Map Browser into an available spot in the  Material Editor. Then apply this material to the V-Ray proxy in the  scene.<br />
Now you have your grass proxy with it's material assigned, ready to be instanced in order to create a field of grass.<br />
<br />

<img alt="" height="507" src="http://www.evermotion.org/files/tutorials_content/3.2-Import-V-Ray-proxy.gif" width="640" /><br />
</span><br />
<br />
<div class="secondMenu">4: Array:</div><br />
<span style="font-size: 15px;"><br />
Now you just need to use the Array tool of 3ds max to multiply your square of grass to create a field of grass.<br />
Using the 'Top' view is recommended for this step.<br />
Here are my settings for the Array tool :<br />
X = 99cm.<br />
Type = Instance (very important!).<br />
Count 1D = 60.<br />
Dimensions = check '2D'.<br />
Count 2D = 60.<br />
Incremental row offset : Y = 99cm.<br />
You can preview your array ; you can also undo and retry if needed.<br />
Basically the aim here is to obtain a 60x60 repetition of your original square of grass.<br />
I used a distance of 99cm instead of 100cm so that the squares slightly  overlap on their edges to have a better continuity between them.<br />
<br />

</span><br />
<br />
<div style="text-align: center;">A D V E R T I S E M E N T<br />

<br />
<br />
<div class="secondMenu">5: Chaos!</div><br />
<span style="font-size: 15px;"><br />
In order to avoid visual repetition of your repeated grass squares you have to rotate them randomly, by increments of 90°.<br />
I used the 'Random Select' MaxScript for this.<br />
Free download here : <a href="http://www.cgplusplus.com/maxscript-en/random-select.html" rel="external nofollow">http://www.cgplusplus.com/maxscript-en/random-select.html</a><br />
To use the 'Random Select' MaxScript you just have to drag and drop the  downloaded .mse file into your 3ds max viewport. The script will appear  in a pop-up menu.<br />
For the following process I recommend to set the rotation snap to 45°,  and you need to set the rotate tool on 'Use pivot point center' mode  (very important!).<br />
Using the 'Top' view is recommended for the next steps.<br />
Now you are ready to create some chaos in your field of grass :<br />
Deselect all.<br />
Random Select script : % = 25 then hit 'Select', then with the 'Rotate'  tool of 3ds max manually rotate these squares of 90° (or enter '90' in  the proper transformation field at the bottom of the screen). Then hide  this selection.<br />
Random Select script : % = 33 then hit 'Select' then with the 'Rotate'  tool of 3ds max rotate these squares of 180°. Then hide this selection.<br />
Random Select script : % = 50 then hit 'Select' then with the 'Rotate'  tool of 3ds max rotate these squares of 270°. Then unhide all.<br />
Now a quarter of the grass proxies are not turned (original  orientation), a quarter are turned of 90°, a quarter are turned of 180°,  and a quarter are turned of 270°. This is quite enough to break the  visual repetition of the rendered grass.<br />
<br />
To add more variation into your grass squares you can select one line  out of two and decay this selection of 50cm on the left or right.<br />
<br />
At this point you have a nice 60x60m field of grass. <br />
<br />
<img alt="" height="640" src="http://www.evermotion.org/files/tutorials_content/5.1-Chaos%21-launch-script.gif" width="640" /><br />
<img alt="" height="640" src="http://www.evermotion.org/files/tutorials_content/5.2-Chaos%21-use-script.gif" width="640" /><br />
<img alt="" height="640" src="http://www.evermotion.org/files/tutorials_content/5.3-Chaos%21-decay.gif" width="640" /><br />
</span><br />
<div class="secondMenu">6: Grouping:</div><br />
<span style="font-size: 15px;"><br />
Select all and create a group.<br />
You now have a field of grass ready to be merged into any 3ds max scene / project.<br />
</span><br />
<div class="secondMenu">7: Merge and rearrange:</div><br />
<span style="font-size: 15px;"><br />
Open the 3ds max project you want to add some grass in.<br />
Go to 'File' then 'Merge' and select the .max file containing your 60x60m field of grass.<br />
Import the grass group. It comes with it's material.<br />
<br />
You probably now have to rearrange the grass squares in order to fit your scene.<br />
<br />
<img alt="" height="526" src="http://www.evermotion.org/files/tutorials_content/Rearrange_the_grass_squares.jpg" width="640" /><br />
In this example I rearranged the grass to fit a swimming-pool, two walk-paths and a house.<br />
You can rotate and overlap grass squares, it's working nicely and this  way you can shape your grass as you need. The only thing to avoid is  having an empty spot between two squares of grass.<br />
</span><br />
<div class="secondMenu">8: Render: with or without Global Illumination, that is the question:</div><br />
<span style="font-size: 15px;"><br />
a) If you want to render the grass with Global Illumination it's much  simpler to setup and much longer to render. In V-Ray you just have to  enable GI, change the render settings as you please, and hit render!<br />
Lighting the grass with a VRaySun + VRaySky works good (see the renders on top of the page).<br />
<br />
b) If you want a fast render (without Global Illumination) you have to prepare a few things.<br />
Select the grass group, then right-click, then 'V-Ray properties', then  uncheck 'Generate GI' and 'Receive GI'. This way you have GI enabled for  the rest of your scene but not for the grass.<br />
In this case you may need an additional light to properly illuminate the  grass. This light should be quite parallel to the camera and should  'Exclude' everything in the scene except the grass.<br />
If you have problems with the shadows in the grass creating dark / black  areas (the self-shadows of the grass) you just have to disable the  'Cast shadow' for the grass group, in the 'Exclude' menu of your main  light source (your VRaySun for example).</span></div><br />

   This tutorial will show you how to texture a scene. I will try to do a simple texturing job on a complex scene (a lots of objects). So the whole texturing is going to be done only in 3DStudioMax.<br />
The main problem is that we are going to texture an architectural scene. Surfaces on scenes like this are big. For example, part of front facade, left of the entrance is 5 meters (16.5 feet) wide and 7 meters (23 feet) high. So if you want to texture it with bricks, that's one hell of a big brick map. And the biggest brick map I ever so was 3 meters (10 feet)in with and 1.5 meters (5 feet) high, so even with this one there are going to be some repetitions. So its up to you to make that repetitions as less visible as you can.</div>    When I first get my hands on <b><a href="http://www.3dtotal.com/">Total Textures</a></b> I was delighted. I spent just couple of hours browsing trough those maps. These maps are great, especially for close up scenes, but can they be used on big surface scenes. You bet they can.....I will try to texture this scene just by using Total Textures.<br />

There is only one omni light lighting the house, but you can insert a few more to lit it more and see better what are you doing with textures. Do not forget to delete those extra lights before rendering.

<tr valign="top"> <td><img border="0" src="http://www.evermotion.org/tutorials_old/texturing/hause/01.jpg" /><br />
</td><td>      The first thing I done was to apply a texture to that big surface left of the entrance. Used a standard max material, with re014.jpg map (total texture V.3) in diffuse slot. What I got was big ugly dirty red wall. To calm it down a little tile it U=2, V=2. Its better a little bit but map is repeating, so pick a uvw mapping gizmo and move it up. Maybe we could hide some erupting parts of the map in back of windows.      </td></tr>
<tr valign="top"> <td colspan="2">   <div align="center"><br />
<span style="color: #f2f2f2; font-size: x-small;">     Maps that have no big contrast in color and shapes you see on them are the best for erupting.<br />

<tr valign="top"> <td><img border="0" src="http://www.evermotion.org/tutorials_old/texturing/hause/re014.jpg" /><br />
</td><td>      But with this one is going to difficult. See that dark part of the map at the top. Its going to be visible when you repeat it just once. See image on left.      </td></tr>
<tr valign="top"> <td><img border="0" src="http://www.evermotion.org/tutorials_old/texturing/hause/mat.jpg" /><br />
</td><td>      Before we go any further lets see how you make those materials. Open a Material editor. Click on any gray ball. This is going to be a material. On left you see a Standard material setup. Put a desired map in Diffuse map slot, and a matching black and white map in Bump map slot. Sometimes you can use a bump map as a Specular map too. Now is up to you to set those other parameters to get the result you want. Ant every material is different and unique.<br />

<tr valign="top"> <td><img border="0" src="http://www.evermotion.org/tutorials_old/texturing/hause/03a.jpg" /><br />
</td><td>      Second thing I done was to make a brick material and apply it to middle part of front facade. What I saw was a big size bricks on front and side walls. Its time to adjust that map. After experimenting a little bit I got satisfying results with U Tile=4.5 and V Tile=8.0 ( see image below)      </td></tr>
<tr valign="top"> <td><img border="0" src="http://www.evermotion.org/tutorials_old/texturing/hause/03.jpg" /><br />
</td><td>      Tiling adjustments can be done in Material editor for every map separately or in UVW Mapping modifier.      </td></tr>
<tr valign="top"> <td><img border="0" src="http://www.evermotion.org/tutorials_old/texturing/hause/02.jpg" /><br />
</td><td>      I prefer for this scene to make a material and to adjust tiling for every object separately in UVW map modifier. If this does not help try to select a mapping gizmo and scale it or move it to get satisfying results.      </td></tr>
<tr valign="top"> <td><img border="0" src="http://www.evermotion.org/tutorials_old/texturing/hause/tex.jpg" /><br />
</td><td>      If you have a map that is 982x618 pixels, and you are going to apply it to 400x400 units object, Max is going to squeeze that map in to the object boundaries and map will be unnaturally scaled. So UVW Mapping modifier will help you to get that map look natural and in best size.      </td></tr>
<tr valign="top"> <td><img border="0" src="http://www.evermotion.org/tutorials_old/texturing/hause/uvwmapping.jpg" /><br />
</td><td>      This is that UVW Mapping modifier. Starting from the top, see that gizmo is active and you can work with transforming it. Mainly I use box mapping. And at the end is Tiling adjustments.      </td></tr>
<tr valign="top"> <td><img border="0" src="http://www.evermotion.org/tutorials_old/texturing/hause/04.jpg" /><br />
</td><td>      Next, to apply brick material to this box object that represent support for entrance roof. Now we have to adjust that material so the bricks must be the same size as those on the wall.      </td></tr>
<tr valign="top"> <td><img border="0" src="http://www.evermotion.org/tutorials_old/texturing/hause/05.jpg" /><br />
</td><td>      This is done. See how the bricks are the same size on both object (wall and box). There are two same box objects in scene. We are not going to do again same adjustments on that other box. But yes he has to look almost the same.<br />
       </td></tr>
<tr valign="top"> <td><img border="0" src="http://www.evermotion.org/tutorials_old/texturing/hause/06.jpg" /><br />
</td><td>      What we are going to do is open Edit Modifier Stack and copy UVW Mapping modifier from first box and paste it to second box Modifier Stack. So the work is done faster and easier.      </td></tr>
<tr valign="top"> <td><img border="0" src="http://www.evermotion.org/tutorials_old/texturing/hause/08.jpg" /><br />
</td><td>      Lets see the whole picture. You can see how that brick map is repeating on that front wall. Lets hope that with light and shadows we will cover that up. You can always take front picture of that wall, take it to photoshop and there paint a brick map and get rid of repeating parts. But we are not going to do that this time.<br />
       </td></tr>
<tr valign="top"> <td><img border="0" src="http://www.evermotion.org/tutorials_old/texturing/hause/09.jpg" /><br />
