Hello, @SupportiveEntity
First of all, thank you very much for your helpful guidance and for sharing that great video which really helped me address the issue. I truly appreciate your support. 
I was wondering if you happen to know anyone who could assist me in better understanding the rendering, materials, and post-process sections? I’m looking for someone with experience who can help clarify these topics.
Also, regarding 3D Imposters, I have read about them in the Unreal Engine documentation before, but I haven’t been able to find any tutorials or practical guides on how to effectively use this feature. If you know of any good resources or tutorials that explain how to properly utilize 3D Imposters, I would be very grateful if you could share them with me.
Thanks again for your time and help!
