PolyCam scan to VAM. Texture looks very low quality. How to make it good?

[EMPIR]

My room texture looks good on Polycam but whenever i import it on VAM texture looks way worse and low quality. I followed this guide. https://hub.virtamate.com/threads/ipad-lidar-scanning-your-room-and-import-into-vam.6345/

Is there anyway to make it better quality texture?
