Exception"The type initializer for ‘Aspose.ThreeD.Render.Vulkan.Vk" on rendering 3D file using Aspose.3D for .NET


I am trying to render (123.1 KB) file on 64 bit system (Window Server 2016) and I am getting “The type initializer for ‘Aspose.ThreeD.Render.Vulkan.Vk’ threw an exception.” error message. I am using below code snippet

// Initialize a Scene class object
ThreeD.Scene scene = new ThreeD.Scene();

					// Load an existing 3D document

					Camera camera = new Camera();
					scene.RootNode.CreateChildNode("camera", camera);
					camera.ParentNode.Transform.Translation = new ThreeD.Utilities.Vector3(10, 10, 10);
					camera.LookAt = ThreeD.Utilities.Vector3.Origin;

					// Specify the image render option
					ThreeD.ImageRenderOptions opt = new ThreeD.ImageRenderOptions();
					// Set the background color
					opt.BackgroundColor = System.Drawing.Color.AliceBlue;
					// Tells renderer where the it can find textures

					if (!Directory.Exists(AppSettings.OutputDirectory + folderName + "/textures"))
						Directory.CreateDirectory(AppSettings.OutputDirectory + folderName + "/textures");

					opt.AssetDirectories.Add(AppSettings.OutputDirectory + folderName + "/textures");

					// Turn on shadow
					opt.EnableShadows = true;

					// Render the scene in given camera's perspective into specified png file with size 1024x1024
					scene.Render(camera, imagePath, new Size(1024, 1024), ImageFormat.Png, opt);

Looking forward to hear from you.



I have worked with source file shared by you and unable to observe any exception. Can you please share which version of Aspose.3D you are using on your end. Also please share complete environment details with us.


I ran the Aspose.3D Github Examples, I got this error too. Please see this image for more help.

The error is thrown on this line as shown in the screenshot.

        var renderer = Aspose.ThreeD.Render.Renderer.CreateRenderer();


We are looking into it and will get back to you shortly.

I am trying to render (300.3 KB)

This is the error.

Thank you.


Can you please your sample code so that we may further investigate this issue on our end along with environment details so that we may further investigate to help you out.

Thank you for reply.

This is the sample code I tried.

public class RenderToFile extends RenderBase {
public static void run() throws IOException {

    Scene scene = new Scene();
    Camera camera = setupScene(scene);
    String output = RunExamples.getOutputFilePath("render-to-file.png");
    //Scene.render uses ImageIO internally, what output format is supported depends on your JRE.
    scene.render(camera, output, new Dimension(1024, 1024), "png");
