defining material

[LordGarth]

Hello,

What does defining a material actually do?

Thx,

Each 3d model file in Grimrock (.model) makes reference to one or more materials for the parts that make it up (segments). When the game loads the model, the model only has a reference to the names of the materials it expects and then the engine links the model to a given material so the it can render its texture on screen.

I guess there are 2 major implications:

1. It might be possible to redefine a material to reskin all instances of one type of bad guy / item in the game. I have not tested this, so don't know it's possible - but the theory is if you can redefine 'long_sword' to link to a different texture, all long swords in the game would look different.

2. Unless I'm missing something, Re-skinning a model then becomes a case of cloning that model and modifying the file slightly so that it links to a diffent named material. That would then allow you to make variants of assets - such as a red sword for instance.

Hope this explanation makes some sense!

Yep, you can use defineMaterial() to redefine existing materials and create new ones.

That is what I was hoping for and I have tried it but it does not work.

I am not sure what part of the puzzle i am missing.

cloneObject{

name = "redgoromorg",

baseObject = "goromorg",

meshName = "redgoromorg_mesh",

}
defineMaterial{
name = "redgoromorg_mesh",
diffuseMap = "mod_assets/textures/redgoromorg_dif.tga",
specularMap = "mod_assets/textures/redgoromorg_spec.tga",
normalMap = "mod_assets/textures/redgoromorg_normal.tga",
doubleSided = false,
lighting = true,
alphaTest = false,
blendMode = "Opaque",
textureAddressMode = "Clamp",
glossiness = 20,
depthBias = 0,
}

When I place the monster I get this error and I have the cloneobject above and definematerial aswell.

As far as I can tell the mesh name is not in the model file itself so it wont work.
