problem intersection walls

[bagiolino]

hello to all, I can't understand how you manage the priority of the union of two orthogonal walls among them.
In practice, I have designed 2 identical walls but which differ only and exclusively from the type of external coating.
sometimes the union between the 2 walls does it correctly while sometimes not.
I attach an image to make you understand better.
I would like wood (brown sheet) to have priority on stone (grey sheet). in practice should be like the crossroads of the left!
Thank you all!

generally because one layer has the highest priority of another you can:

1- put one inside the nucleus and one outside. the layers outside the nucleus have lower priority.

2-if both are within the nucleus you can assign to a function with lower priority (a lower value of the numerals next to the function name).

try to post an image with the structure(understood as functions and layers) of the wall maybe someone can give you a more specific advice.

Hi.

the walls are exactly the same, what changes is the outer coating that is out of the nucleus and type "finish 5".
Obviously it does not merge them because they are different materials, but at least I would like to know if it is possible to decide which one must "prevalence" on the other!
