floor is reflected to ceiling, looks totally unrealistic

Hi. When I use path tracer in most of my renders the colour of the floor is almost 100% reflected in the ceiling. Its looks utterly ridiculous. For instance if the floor is wood parquet then the ceiling which should be white is brown.

How can I stop this behaviour. I need the floor to be wood but the ceiling to be white, can I not tell twinmotion to not reflect the floor or something?

Hi Gareth and thank you for posting in our community. I'm sure you tried already but if not, try raising the roughness of the ceiling material.

Otherwise, maybe this video could help: https://www.youtube.com/watch?v=XlFQ2HbiGvY
