Vector4 variable

package custom;

public class MaterisalParams implements Serializable {
    public  Vector4  diffuse;

    public Vector4   ambient;
    public boolean   backfaceShadows;

    public Vector4   specular;
    public float     shininess;
    
 //name Shininess type Float
 //   Specular specular;
  // Shininess shininess;
}

Compile with errors.

i get material parameters.

Collection<MatParam> listMap =  material.getParams();
        
       for(MatParam param : listMap){
       
           System.out.println(" name " + param.getName() + " type " + param.getVarType());

       }

And add to custom class:

package custom;

//import static com.jme3.shader.VarType.Texture2D;
import com.jme3.shader.VarType.Vector4;
import com.jme3.texture.Texture2D;
import java.io.Serializable;

/**

public class MaterisalParams implements Serializable {
    public  Vector4  diffuse;
    public boolean   useMaterialColors;
    public float     parallaxHeight;
    
    public Vector4   ambient;
    public boolean   backfaceShadows;
    public Texture2D diffuseMap;
    public Vector4   specular;
    public float     shininess;
    
 //name Shininess type Float
 //   Specular specular;
  // Shininess shininess;
}

When i run application compiler not search type: Vectro4.
import com.jme3.shader.VarType.Vector4;

(cannot find symbol Vector4)

And Texture2D have 2 class:
import com.jme3.texture.Texture2D;
//import static com.jme3.shader.VarType.Texture2D;

which used in material parameters?

It’s just “Texture” from the java point of view - so it would be com.jme3.texture.Texture.

Example:

import com.jme3.texture.Texture
// ...
Texture texture = assetManager.loadTexture("Textures/Earth/grass_diffuse.jpg");

Than’ks
And import Vector4 not work:
import com.jme3.shader.VarType.Vector4;

You want a Vector4f :stuck_out_tongue: com.jme3.math.Vector4f

Okay thanks.

how you think: uv map save in material parameters?

This does not apply to the material, it’s vertex data.

Okay. Where stored (saved) uv map coordinates?

Logically in the mesh.

If I understand, you want to get a material from a model. I can’t really write it any better than paul already did in an example.

I have:
1 blender model
2 materials
2 uv maps
2 textures

In blender i can assign one material (of two).

Logic:

  1. I assign material

  2. I get material in jmonkey

  3. I save material to string (and restore when it need)

  4. I set needed material

       Node node         = (Node) assetManager.loadModel(modelPath);
    Geometry myGeo    = (Geometry)node.getChild("base.obj1");
    Material material = myGeo.getMaterial();
     
     
    Collection<MatParam> listMap =  material.getParams();
     
    for(MatParam param : listMap){
    
        System.out.println(" name " + param.getName() + " type " + param.getVarType());

    }
    MaterisalParams matParams = new MaterisalParams();

//next i assigned parameters. save all materials to string. and restore need material when need.

I dont understand. Why do you need to save the state of a material? A material is a representation of a state. It displays the state, it is not a state itself.

In blender:
material have uv map…

I need switch between two textures (between two uv map two material two textures)

But it’s not possible with jmonkey standart methods.

Sure it is, but i think you maybe confuse yourself over-thinking. Just use a method or a class to do it.

private Material material;

public SomeClass() {
    this.material = myModel.getMaterial();
    setState1();
}

public void setState1() {
    material.setTexture("Diffuse", someTexture);
    // and everything else...
}

public void setState2() {
    material.setTexture("Diffuse", anotherTexture);
    // and everything else
}

Then call setState1() or setState2() whenever you want to change the material state.
Sorry for any typing errors, i am on my phone.

Note that the variable you have with the material, you can create the variable Army and Spec. And apply them as needed.

Just use individual variables. Dont base64 encode it. It wont help anything. I see no sense in it.

Material mat = geom.getMaterial();

Do not be stupid, mat this is already a variable.
