Is there a simple and high rendering quality archviz program?

Hello, folks.
I want to ask some problems about the archviz program.
Is there an architectural visualization program that is simple enough to open and render an FBX file, but guarantees the high quality of rendering?
if there is, is it open source?
I hope your help.
Thank you in advance.

Hey @garry0905, I’d recommend checking out Twinmotion here: https://www.twinmotion.com/en-US, which is part of the Epic Ecosystem. Awesome quality renders with minimal effort. You can also export your Twinmotion scenes over to Unreal Engine.

Kind regards,

Simon
