Hi larsbertram1 Were have problems in our current game with Unity terrain system taking to much loading time in frames for the grass details. Look at you ATG plugin it could be the solution for fixing our problem. But after reading the first post on this thread I have some questions over the following points: - Billboarded grass is not supported. Thus this means that there is no support for rotating meshes to the camera or/and no support for panel like grass meshes? - ATG currently does not support to reset the world’s origin and move terrains around to handle floating point issues. Thus this mean dat once the ATG grass is loaded at a terrains location that it won't move when the terrain is moved? Looking forward to your answers.
