+## **FAQ**
 
-We continue to improve our 3D Engine, and these features are the subject of further implementation.
+**Will 3D effects be preserved when exporting a presentation to images/PDF/HTML?**
 
- 
+Yes. The Slides 3D engine renders 3D effects when exporting to supported formats ([images](/slides/cpp/convert-powerpoint-to-png/), [PDF](/slides/cpp/convert-powerpoint-to-pdf/), [HTML](/slides/cpp/convert-powerpoint-to-html/), etc.).
 
+**Can I retrieve the "effective" (final) 3D parameter values that account for themes, inheritance, etc.?**
+
+Yes. Slides provides APIs to [read effective values](/slides/cpp/shape-effective-properties/) (including for 3D—lighting, bevels, etc.) so you can see the final applied settings.
+
+**Do 3D effects work when converting a presentation to video?**
+
+Yes. When [generating frames for the video](/slides/cpp/convert-powerpoint-to-video/), 3D effects are rendered just as they are for [exported images](/slides/cpp/convert-powerpoint-to-png/).

+## **FAQ**
+
+**Do I need to install Microsoft PowerPoint or LibreOffice to convert ODP to PPTX?**
+
+No. Aspose.Slides works standalone and does not require third-party applications to read or write ODP/PPTX.
+
+**Are master slides, layouts, and themes preserved during conversion?**
+
+Yes. The library uses a full presentation object model and retains structure, including master slides and layouts, so the design remains correct after conversion.
+
+**Can I convert password-protected ODP files?**
+
+Yes. Aspose.Slides supports detecting protection, opening and working with [protected presentations](/slides/cpp/password-protected-presentation/) (including ODP) when you provide the password, as well as configuring encryption and access to document properties.
+
+**Is Aspose.Slides suitable for cloud or REST-based conversion services?**
+
+Yes. You can use the local library in your own backend or [Aspose.Slides Cloud](https://products.aspose.cloud/slides/family/) (REST API); both options support ODP → PPTX conversion.

 Aspose.Slides provides the ability to convert presentations into various formats, including creating handouts for printing in Handout mode. This mode allows you to configure how multiple slides appear on a single page, making it useful for conferences, seminars, and other events. You can enable this mode by setting the `set_SlidesLayoutOptions` method in the [IPdfOptions](https://reference.aspose.com/slides/cpp/aspose.slides.export/ipdfoptions/), [IRenderingOptions](https://reference.aspose.com/slides/cpp/aspose.slides.export/irenderingoptions/), [IHtmlOptions](https://reference.aspose.com/slides/cpp/aspose.slides.export/ihtmloptions/), and [ITiffOptions](https://reference.aspose.com/slides/cpp/aspose.slides.export/itiffoptions/) interfaces.

+## **FAQ**
+
+**What is the maximum number of slide thumbnails per page in Handout mode?**
+
+Aspose.Slides supports [presets](https://reference.aspose.com/slides/cpp/aspose.slides.export/handouttype/) up to 9 thumbnails per page with horizontal or vertical ordering: 1, 2, 3, 4 (horizontal/vertical), 6 (horizontal/vertical), and 9 (horizontal/vertical).
+
+**Can I define a custom grid, such as 5 or 8 slides per page?**
+
+No. The number and ordering of thumbnails are controlled strictly by the [HandoutType](https://reference.aspose.com/slides/cpp/aspose.slides.export/handouttype/) enumeration; arbitrary layouts are not supported.
+
+**Can I include hidden slides in the Handout output?**
+
+Yes. Use the `set_ShowHiddenSlides` method in the export settings for the target format, such as [PdfOptions](https://reference.aspose.com/slides/cpp/aspose.slides.export/pdfoptions/), [HtmlOptions](https://reference.aspose.com/slides/cpp/aspose.slides.export/htmloptions/), or [TiffOptions](https://reference.aspose.com/slides/cpp/aspose.slides.export/tiffoptions/).

+## **FAQ**
+
+**What is the performance of Aspose.Slides when converting multiple presentations to HTML?**
+
+Performance depends on the size and complexity of presentations. Aspose.Slides is highly efficient and scalable for batch operations. To achieve optimal performance when converting many presentations, it’s recommended to use multithreading or parallel processing whenever possible.
+
+**Does Aspose.Slides support exporting hyperlinks to HTML?**
+
+Yes, Aspose.Slides fully supports exporting embedded hyperlinks to HTML. When you convert presentations to HTML format, hyperlinks are preserved automatically and remain clickable.
+
+**Is there any limit on the number of slides when converting presentations to HTML?**
+
+There is no limit on the number of slides when using Aspose.Slides. You can convert presentations of any size. However, for presentations containing a very large number of slides, performance may depend on the available resources of your server or system.

+
+**Do hyperlinks survive the export to Markdown?**
+
+Yes. Text [hyperlinks](/slides/cpp/manage-hyperlinks/) are preserved as standard Markdown links. Slide [transitions](/slides/cpp/slide-transition/) and [animations](/slides/cpp/powerpoint-animation/) are not converted.
+
+**Can I speed up conversion by running it in multiple threads?**
+
+You can parallelize across files, but [don’t share](/slides/cpp/multithreading/) the same [Presentation](https://reference.aspose.com/slides/cpp/aspose.slides/presentation/) instance across threads. Use separate instances/processes per file to avoid contention.
+
+**What happens to images—where are they saved, and are the paths relative?**
+
+[Images](/slides/cpp/image/) are exported to a dedicated folder, and the Markdown file references them with relative paths by default. You can configure the base output path and asset folder name to keep a predictable repository structure.
