Hi Sai,

I have observed the missing shapes in the rendered image as shared by you and its a deficiency in Aspose.Slides. The requested feature for rendering of 3-D shapes is not yet implemented in Aspose.Slides for Java. Please share your source presentation, so that we ma reproduce the issue on our end and add it in our issue tracking system for further investigation and resolution. We appreciate your cooperation in advance.

Thanks and Regards,
