2. Load your project > go to “Edit” from the top menus > Plugins > Activate the VaRest plugin for your project and restart UE4

3. Download the two UE4 functions that you’ll need – https://svr.li/producer/ue4/functions and extract them under the Source folder of your project. Optionally, you can create new cpp files through UE4 and paste the code.

4. Create a new Blueprint:

5. Select the first option (Actor) and then select the “Blueprints” category and give it a name.

6. Edit the newly created Blueprint and switch to the “Event Graph” view.

7. Copy the default Blueprint settings ( for UE4 version before 4.24: http://svr.li/producer/ue4/blueprint  ;  for 4.24 or newer: http://svr.li/producer/ue4/blueprint4.25 ) and paste (ctrl+v) under Event Graph. The Blueprint will look like this:

and set the Value Name to:

10. Locate your “BeginPlay” event and assign the “Synthesis Verification” functionality

You are ready to compile the Blueprint.

12. Upload the build on SynthesisVR CDN (link)
