- The @'Stride.Rendering.Material' class is the runtime material shader generated from the @'Stride.Rendering.Materials.MaterialDescriptor'

|
|
+The file @'Stride.Rendering.Materials.MaterialKeys' contains most material keys you might need to use, have a look through it to figure out which one you might need to get to modify the parameter you are interested in.

|
|
|
+Let's say you have this fairly simple material
|
|
|
+
|
|
|
+
|
|
|
+And you want to clone that material, but change its color to red at runtime.
|
|
|
+Searching through the different keys contained in @'Stride.Rendering.Materials.MaterialKeys' you would find `MaterialKeys.DiffuseValue` and use it as the key to set the new color value you want:
|
|
|
+```csharp
|
|
|
+var clone = SerializerExtensions.Clone(MyMaterial);
|
|
|
+clone.Passes[0].Parameters.Set(MaterialKeys.DiffuseValue, new Color4(1, 0, 0));
|
|
|
+```
|
|
|
+
|
|
|
+If you aren't too sure which parameter keys your material uses, the best way to figure it out would be to inspect the material's variables with a debugger.
|
|
|
+Here's an example of that through Rider's *Threads & Variables* window:
