Ogre3D materials take the full power out of your 3D hardware. realXtend 0.4 supports materials. Find out how to take them into use!
It is possible to use complex materials in Realxtend, with for
instance specular map, normal maps, alpha maps etc
To accomplish that it's required to use an Ogre's material
script. The easiest way is to choose one from the examples included
in the Rex viewer. They can be found in the installation folders of
Realxtend viewer : RealXtend\media\materials\scripts.
This is a step by step tutorial for utilize a material with
diffuse, normal and specular maps.
The diffuse map is an rgb file with the colors of the object (the
base texture). The normal map give relief informations and it's
another rgb file. The specular map, that sets the shine values it'
s a grayscale file (what is white shines, what is black doesn't)
.
1/ Launch Realxtend viewer and log into a server where you have
the right to build (rexpioneers for example!)
2/ Go into the menu « File » then
« Upload Material Script »
3/ Search into the folder
« RealXtend\media\materials\scripts » of your
Rex viewer and choose a material script called
« SSDiffSpecmapNormal.material ». A pop-up
window opens, click on « Upload ».
4/ Go into the menu « File » then
« Bulk Upload » (it allows to upload several
files together). Select your 3 textures (a base map, a normal map
and a specular map) and upload them.
5/ Open your inventory.
You must have a material script there called SSDiffSpecmapNormal.
Right-click on it, then choose « Edit
Parameters ».
6/ In the Material Script Editor, double-clic on "baseMap". A
"baseMap" field appears at the bottom of the window. Drag and drop
the diffuse map from your inventory to the base map field. Do the
same for the normalMap and specularMap.
7/ At the top of the Material Script Editor, change the name of
the material and click enter (if you don't you won't be able to
save the material).
8/ Clic on "Save As".
9/ Select an object, right-clic on it and choose "Edit". Go to
the "reX" tab then to the "Material" tab inside it. Drag and drop
your new material from your inventory in the first field (if you
want to apply the material to the first UV set of the object).
10/ You now should see your object with the combined textures
you have uploaded. See the example below :
