I’m not sure if this is intentional or not, but prior this, a union’s material direction would be based on whichever part you had selected first, which this no longer seems to be the case.
It now always takes on the direction of one of the parts, no matter the selection order.
Selecting either one first will result always in this direction
Without the beta enabled though, if I select the lefthand (horizontal) part first, it’ll go in that direction.
