Hello. Please tell me how to fix the problem. There is an array of ground modeled by the tool Terrain and assigned to it the construction material of the ground with a low numerical priority. https://www.bigbootyporn.tv/ If we stick for example a concrete column in this ground and apply to it the building material concrete with a higher priority than that of the ground, and make a 3D section along the axis of the column, it is clear that the model relief does not work priority of building material and extra ground volume is not subtracted from the volume of concrete. Does anyone know why construction material priorities do not work with the Terrain tool ? Thanks.
