I'm not sure what you are referring to by "losing quality". Do you have comparison screenshots or did you mean the performance (fps) degrades?
Please provide more detailed information.
The image with the purple numbers is what appears when I start the game in Construct. However, over time, the 3D objects start to show more visible pixels. I don't know if it's an operational problem with my computer or something with the plugin. If it's related to the plugin, I'd like to know how to solve it. Thank you for your quick response.
