They look awful when working at Medium quality, at high or ultra they look better.
Hi,
Thank you for reaching out, this will be an effect of simplifying the polygons in the lower quality settings. This will be consistent across previous and current Twinmotion versions and allows for better performance when working in the viewport. Please know this will only effect the way the models are displayed in the viewport - when exported in media, they will render in Ultra quality and appear as expected.
For more information on Twinmotion's Quality Settings, please see our documentation here: Twinmotion Preferences
Best Regards,
Morgan
