Getting exception: Insufficient memory to continue the execution of the program

With the current version (22.3.0) of the Aspose.3D .NET library (running under .NET 6.0 on Windows, with NVIDIA card), we’re getting this exception below.

I have 64GB of RAM (and 20 cores), and 32GB+ of RAM free, so it’s not literally running out of memory.

Any ideas what could be causing this, or what a workaround may be?



I’ve gotten this exception on a variety of scenes, which I believe used to work fine.

Insufficient memory to continue the execution of the program.

With this code, where scene.Render is throwing this exception:

            var bbox = scene.RootNode.GetBoundingBox();

            var cam = new Camera(ProjectionType.Perspective)
                NearPlane = 0.1,
                FarPlane = 1000,

            scene.RootNode.CreateChildNode(cam).Transform.Translation = bbox.Maximum * 4;

            var center = (bbox.Maximum + bbox.Minimum) / 2;

            cam.Target = scene.RootNode;
            cam.LookAt = center;

            scene.RootNode.CreateChildNode(new Light()
                LightType = LightType.Point,
                ConstantAttenuation = 0.3,
                Color = new Vector3(Color.White)
            }).Transform.Translation = new Vector3(30, 10, 10);
            scene.RootNode.CreateChildNode(new Light()
                LightType = LightType.Directional,
                ConstantAttenuation = 0.3,
                Direction = new Vector3(-0.3, -0.4, 0.3),
                Color = new Vector3(Color.White)

            scene.RootNode.CreateChildNode(new Light()
                LightType = LightType.Spot,
                CastShadows = true,
                LookAt = new Vector3(28, 10, -30),
                Color = new Vector3(Color.White)
            }).Transform.Translation = new Vector3(40, 10, 50);

            var opt = new ImageRenderOptions
                BackgroundColor = Color.AliceBlue,
                // Tells renderer where the it can find textures
                //opt.AssetDirectories.Add(RunExamples.GetDataDir() + "textures");
                // Turn on shadow
                EnableShadows = true

            scene.Render(cam, filePath, new Size(width, height), format, opt);


Would you please also share the sample Scene file with us so that we can test the scenario in our environment and address it accordingly.

Hi Asad, I was seeing this happen across a variety of formats (.fbx, .obj, etc).

Here’s a zip of an FBX file which was one with the issue.
