Hi whinter,
Thank you for your question! Currently, Cyberix3D does not support exporting games in windowed mode; the default export option is full-screen.
We understand this might be a desired feature for some users, and we’re always looking for ways to improve the platform.
We will take this into consideration for future updates.
If you have any other questions or need further assistance, feel free to ask!
Best regards,
Cyberix3D Team
