I'm currently learning to use Ogre and I juts got a little problem with it. I'm sure the solution is quite simple, but I can't find it by myself.
Edit : I'm using Ogre 1.6.2
So I'm using Ogre with SDL, as this tutorial explains, and it seems to work great. I loaded a mesh and placed a camera, and it's ok. Now, I want my mesh (in fact, a sphere) to be red. So I used a material script such as this one :
Code: Select all
material Material
{
receive_shadows on
technique
{
pass
{
ambient(0.5,0.0,0.0,1.0)
diffuse(0.640000,0.016345,0.000000,1.000000)
specular(0.500000,0.500000,0.500000,1.000000,12.500000)
emissive(0.000000,0.000000,0.000000,1.000000)
}
}
}Code: Select all
Parsing scripts for resource group General
Parsing script Sphere.material
Finished parsing scripts for resource group GeneralCode: Select all
Mesh: Loading Sphere.mesh.
Can't assign material Material to SubEntity of Ball because this Material does not exist. Have you forgotten to define it in a .material script?Here is the source code of my Renderer class. All of my calls to Ogre are in this file :
Code: Select all

Thanks very much for any help.
. Let's wait and see.
