== How to create a Terrain ==
<blockquote>
New regions have a default terrain that look like a small island in the middle of a 256 x 256 meters region. 
You can use the '''Build''' tool to terraform the terrain (''caterpillar icon'')
|[[Image:Q-Sims 1st screen 2.jpg|thumb|300px|center|Default terrain]]

There are possibilities to quickly and easily define the shape of your terrain using an image.

|}

The greylevel correspond to the Height field. Once in an '''OpenSim console''', type: <pre> terrain load <filename></pre>
where <''filename''> correspond to the picture (''BMP, TIF, JPG, PNG'').
</blockquote>
NOTE: Up to now, I have not succeeded this way. 

== How to generate a terrain using L3DT ==

I use another method to generate terrain thanks to the very valuable L3DT software.
<blockquote>
*'''Brush your land''' in your favorite paint tool and save it as a PNG or JPG image (''JPEG image introduces some block artifacts due to the DCT compression method'') - For information ''North'' is up and ''South'' is down.
*'''Download''' the L3DT Standart Edition [[http://www.bundysoft.com/L3DT/downloads/ L3DT ]]
 '''in L3DT''':
*'''File''' / '''New project''' / ''Designable map'' (1/5)
*in ''Heightfield (2/5)'' set ''Horiz. scale'' to "1" and set the width/height to your terrain size (''256x256 per region'', with 4 regions you shall enter 512x512)
*in "''Design map size (3/5)''" leave 64
*in "''Design map parameters''" leave as is (4/5)
*in "''Design map''" (5/5) lease as is and click "OK"
*'''File''' / '''Import''' / ''Heighfield''
*in "''Import height map (1/2)''" browse your to your image file
*in "''Heightfile import options (2/2)''" set "Horizontal scale" (1 pix = x meters, in our case =1) and choose the Min (''-20 deep sea'') /Max altitude
 
*Do any tuning if you want (''I did no tuning in this example'')
 
*'''File''' / '''Export''' / '''Export map''' / Heightfield
*Choose R32 and check Options / InvertY = false
 '''In Opensim''' : in the console type : <pre>terrain load-tile <filename> x1 y1 posX posY</pre>
''where x1 and y1 are the numbers of H/V tiles (''one tile is 256x256'') and posX/posY correspond to the region at the left-bottom of the terrain.'' 

*eg. a jpeg 512x512 pix image save into bin/../backup/my_reg.r32 to cover 4 regions (1000-1000,1001-1000,1000-1001,1001-1001) will require the following command:
<pre>terrain load-tile ../backup/my_reg.r32 2 2 1000 1000</pre>
NOTE:

*In OpenSim the sea level is 20, therefore you may have to do "'''terrain elevate 20'''"
*You may also apply "'''terrain rescale <min> <max>'''" to fit you expectations.
