Releasing a patch

How to create a distributable patch

After the developer has produced and tested the patches using both the Node patching and/or the Logic patching techniques, the developer creates a distributable .pak file.

1. Open the project in XR Studio.

2. On the Run menu, select Make Patch.

This creates a folder named _patch outside the project folder containing a file name patch.pak. The .pak file is encrypted with the same encryption used when building the project distribution with Make Release or Make Installer .

Note: Observe that as the patch is based on fixed files (patch.xml and patch_logic.xml) sequential patches are not supported. If a second patch is going to be redistributed, it has to extend and override the previous.

How to install the patch

To implement a patch on a delivery machine, follow these instructions.

3. Place the patch.pak file inside the application folder.

4. Modify all the Application Configuration Files included in the application folder by adding patch.pak to the Scene.pak configuration parameter list.
