==Import the materia-templates.material==
-
// see http://www.ogre3d.org/docs/manual/manual_28.html#SEC145
+
Open a file and rename it to the name of the material in your mesh file. For example "basefloortile.material" for the "respective basefloortile.mesh".
-
// can be used by
+
-
// import * from "material-templates.material"
+
-
// --------------- THESE ARE THE ATLAS STANDARD MATERIALS ----------------------
+
Begin the file with the following file without the slashes. The slashes are normally for comments.
-
// MESH BASE MATERIAL TEMPLATE
+
-
material atlas_base

// MESH BASE ALPHA MATERIAL TEMPLATE
 
-
material atlas_base_alpha : atlas_base
 
-
{
 
-

-
{
 
-
pass Decal
 
-
{
 
-

-
ambient vertexcolour
+
This will import the templates and the artist does not have to type very much.
-
diffuse vertexcolour
+
-
alpha_rejection greater_equal 128
+
==Defining the Template and Texture==
-
alpha_to_coverage on
+
 
-
}
+
Then type this and replace the "diffuse_template" with your chosen template and "tex_basefloortile.png" with the texture which you want to use.

}

material basefloortile : diffuse_template

  set_texture_alias diffuse_tex tex_basefloortile.png

Diffuse is the texture for normal light and ambient is what happens if there is no light.

// MESH BASE ALPHA MATERIAL TEMPLATE

For normal Tiles without transparency but still having their own shadow.
-
material diffuse_template_alpha : diffuse_template
+
-
{

-

+
-

+
==diffuse_template_alpha==
-
diffuse vertexcolour
+
-
alpha_rejection greater_equal 128
+
This is good for tiles with transparent textures but still having shadows.
-

-
}
+
-
}
+
-
material diffuse_template_foliage : diffuse_template
+
:Advantage: Does not need a lot of performance
-
{
+
:Disadvantage Not so nice frames and is good for everything with transparency
-

-

-

-
{
+
-
lighting on
+
-
ambient vertexcolour
+
==diffuse_template_sceneblend==
-
diffuse vertexcolour
+
-
cull_hardware none
+
You can take that if the object should not have shadows but still is alpha transparent.
-
cull_software none
+
-
+
-
alpha_rejection greater_equal 128
+
-
alpha_to_coverage on
+
-
texture_unit
+
: Advantage: It has very nice frames. Good for grasses.
-
{
+
: Disadvantage: No real "Tiefensortierung". It is only apparent if you look at it and another mesh also having sceneblend.
-
filtering anisotropic
+
-
max_anisotropy 8
+
-
texture checker.png
+
-
texture_alias diffuse_tex
+
-
tex_address_mode wrap
+
-

material diffuse_template_sceneblend : diffuse_template

==diffuse_template_foliage==
-

+
-
technique default
+
-
{
+
-
pass Decal
+
-
{
+
-

+
-
ambient vertexcolour
+
For objects having models and is alpha transparent.
-
diffuse vertexcolour
+
-
cull_hardware none
+
: Advantage: Object has shadows
-
cull_software none
+
: Disadvantage: Object unfortunately does not have nice frames. Good for flowers and trees.Objekt hat nicht so schöne Ränder (geeignet für Blumen oder Bäume)
-
scene_blend alpha_blend
+
=Beware=
-
depth_write off
+
 
-
depth_check on
+
To test the meshes, material and texture by taking a look on it with the help of [http://www.ogre3d.org/tikiwiki/Ogre+Meshy Ogre Meshy]. You have to copy the "material-templates.material" in the same folder.
