64-bit support Scene Composer
Since CGI3.13, Scene Composer has become a 64-bit support application. As a result, the following benefits are expected when compared to the 32-bit Scene Composer
- Enables creation of complex, large-scale HMI solutions that exceed 32-bit memory limitations
- Ability to import and memory process large, complex assets via the Smart Importer
On the other hand, the C++ SCHost.dll used for launching Scene Composer has to be built as well in 64-bit mode. For this reason, CGI 3.14 or later has a function to automatically check if SCHost.dll is properly built when starting Scene Composer. If you are using SCHost.dll built in 32-bit, the following error dialog will be displayed.

| [ OK ] button | Closes the Scene Composer. |
| [ Open... ] button | Opens the Scene Composer log file with any editor. |
For information on building SCHost.dll for 64-bit support, please refer to Build System Setup document.
The 32/64bit compatibility table for each version of CGI Studio is shown below.
| CGI Version | Scene Composer and SCHost.dll | CGI Player |
| Up to CGI3.3 | 32bit required | 32bit required |
| From CGI3.4 to CGI3.12 | 32bit required | 32bit or 64bit required |
| CGI3.13 and later | 64bit required | 32bit or 64bit required |
