Thanks for buying the polygon office building. Light baking : - Set all to static expect moving objects, door & elevator or any you want to move. - To get good performance and it is really required that you light baking all. It takes a while and depends on you computer performance and which quality you want to get at the end. Performance : - occlusion culling you scene which really saves you much performance. Building : The doors & elevator are already programmed. To fix the elevator flip, you need to programm a fix by you self. If you stand with you Player in it -> Transform the height equal as the evelator current moves. If you jump, turn the holding off until you grounding with you player. Setting up the Player: - Import the standard assets from unity and drag the FPS controller into the scene of the office building <- Or use you player and involve the script "DoorAction" in it. - drag the " Action cube Prefab " into the camera of the FPS controller, so that the "Action cube Prefab" aim forward(The blue arrow) <- you can also only using the script, clear it with you self, how you use it. - Also tag you player as "Player" "e" is the button to performance a action to open the door or to click a button in the elvator for askes feel free to contact me tmg@fn.de.
