I am trying to make a game environment which is going to be a trench system. I have created the texture i would like to tile across the landscape that unreal engine generated. What i would like to do is use the spline tool to try and create an alpha map with zero opacity. The reason for this is so that i can model my trench system within MAYA and then just adjust the rest of the environment within the game engine. Is this possible?
Thanks for any help.
