Hi,

I am trying to create a Xenko.Rendering.Material programmatically. I need to load am image file too as DiffuseTexture.

How can I build it?

Thanks in advance.

i think a material is only an object tree, so start with the top level class and fill all properties and options. it should be a 1 to 1 translation from the material properties in game studio…

For the next person who stumbles upon this forum post looking for an answer…

https://doc.xenko.com/latest/en/manual/scripts/create-a-model-from-code.html

And here is a project sample that runtime loads a wavefront OBJ file, including textures.

github.com

jeske/LoadObjTest/blob/master/LoadObjectTest/LoadAsset.cs#L156


using (var originalImage = Image.Load(inStream))
{
    using (var textureImage = Image.Load(tempStream))
    {
        TestImage.CompareImage(originalImage, textureImage, false, 0, fileName);
    }
}        
 */




// load a texture from a file


var diffuseTextureFilename = System.IO.Path.Combine(assetBase,wfData.materials[0].mtl.diffuseTextureResourceName);
var diffTexStream = System.IO.File.Open(diffuseTextureFilename,System.IO.FileMode.Open,System.IO.FileAccess.Read);
var diffuseTexture = Texture.Load(GraphicsDevice,diffTexStream);




var cc = new ComputeColor();


// Create a material (eg with red diffuse color).
var materialDescription = new Stride.Rendering.Materials.MaterialDescriptor
