Trimmed material not the same as facade material

[Anonymous]

Hello!
How do I get the same material on this section part of the wall, as it is on the facades?
I got this shape of the house by 'Trimming elements to roof' tool.
In both roof and walls properties I checked symbols for 'Override surfaces', and chose the stone material, but this linear part still stays different afterwards.

Thank you!

You must assign a material with a slightly higher priority for the roof to match the original surfaces
Otherwise you can constrain slices of walls and roofs with the desired surface
