+
+\section1 Compressed Textures
+
+Qt 3D Studio supports the Khronos texture container file format \e ktx. You can apply \e ktx files
+as texture maps just as any other file format. However, if your system does not support the \e ktx
+format, the textures will not be visible in Qt 3D Studio.
+
+If you enable the \uicontrol {Use ktx textures if available} feature, you can use \e png
+images in Studio, and then use \e ktx images in their place in the Viewer.
+
+\list 1
+  \li In the Studio menu, click \uicontrol{Edit > Presentation Settings}
+  \li Check the \uicontrol {Use ktx textures if available} check box.
+\endlist
+
+\section1 Optimizing Images
+
+Optimizing the images in your presentation can substantially improve both the startup and runtime
+performance of your application, as well as the visual quality in certain situations. Read more
+about \l{Optimizing Images}.
+
+\section1 Image-Based Lighting
+
+HDR images can be used as light probes for environment lighting in Studio. Read more about
+\l{Image-Based Lighting}.
