I tried using "BLD_Humans_StonePlatform_4x4_B_Dynamic" but that didn't allow the character to walk onto it unless the character started on it. I tried using "1m_CastleHouse_A_Floorwood_4m_Used" instead that seems to work fine. So i guess it has something to do with "dynamic" the seeder comes up purple not sure what that means. Im new to this xD.
