I'm making a house from a floor plan.
Each room has its own plane to be unwrapped and assigned the same tiles material.
Whenever I unwrap a floor plane and assign its material, the material scale is different for each room and I have to eyeball the scale to make the tile seams align.
Is there a more efficient way of unwrapping all planes so the tile seams align properly, or do I just have to give in and make all floor planes into one object?
EDIT: Added picture
In the picture below you can see the floors were unwrapped but each floor scaled differently. On floor has small tiles and one has large tiles. I'd like to unwrap each floor so they have exactly the same scale.
