Hello !
By advance, sorry for my bad english ^^
I export meshs from blender to ogre and I would like to know how to use a specular map (png) in a ogre material. Some one could help me please ?

Thanks

Regular materials don't support specular maps. You'll need to use a shader. There are some shaders that come with Ogre that you might want to learn about.

C'mon, don't be so extrem!

The good the solution is shaders.

The bad solution that works is to simply use 2 passes. And that's all folks !

Best,

I guess that kind of works.
It's just unusual to use a specular map without also using a normal map.

Code: Select all

pass
{
    diffuse 1 1 1 1
    specular 1 1 1 1
    texture_unit
    {
           texture diffuseMap.png
    }
}
pass specularPass
{
    diffuse 0 0 0 0
    emissive 0 0 0 0
    specular 1 1 1 1 64
    ambiant 0 0 0 0
    texture_unit
    {
           texture mySpecularmap.png
    }
    scene_blend add
}

And that's all folks !

This doesn't work, cause specular is applied on top of the texture, disregarding fully the actual texture.
This SHOULD work:
texture_unit
{
colour_op_ex modulate src_specular src_texture
texture crystal-shard_spec.png
}
but not here (Ogre 1.6)
