The WithMips method is a member of the Texture3DBuilder class in the Sandbox namespace. This method allows you to specify the number of mipmap levels for a 3D texture being constructed. Mipmaps are pre-calculated, optimized sequences of images that accompany a main texture, intended to increase rendering speed and reduce artifacts.
To use the WithMips method, you need to have an instance of Texture3DBuilder. Call this method on the instance, passing the desired number of mipmap levels as an integer parameter. This method returns the same Texture3DBuilder instance, allowing for method chaining.
// Create a new Texture3DBuilder instance
Texture3DBuilder builder = new Texture3DBuilder();
// Set the number of mipmap levels to 4
builder.WithMips(4);
// Continue configuring the texture
builder.WithSize(256, 256, 256)
.WithFormat(ImageFormat.RGBA8)
.Finish();
