Tips, Tricks, Errors

    • “If you choose to 'Download and Import' rather than just 'Download' it will place a copy in your project folder. Otherwise, the files are not tied to any particular project, so they are placed int he shared data folder on your local machine”.
    • Just some examples of the download path for complete projects:
      • “C:\Users\<username>\AppData\Roaming\Unity\AssetStore\”.
        • “C:\Users\<username>\AppData\Roaming\Unity\AssetStore\Unity Technologies\Complete ProjectsTutorials”.
        • “C:\Users\<username>\AppData\Roaming\Unity\AssetStore\Allegorithmic\Complete ProjectsUnity Tech Demos”.
        • “C:\Users\<username>\AppData\Roaming\Unity\AssetStore\bisaniyehocam\Complete ProjectPacks”.
        • “C:\Users\<username>\AppData\Roaming\Unity\AssetStore\Exit Games\Complete Projects”.
        • “C:\Users\<username>\AppData\Roaming\Unity\AssetStore\Exit Games\Complete ProjectsTemplates”.
  • On Win8, during software installation, Unity stores a demo project at “C:\Users\Public\Documents\Unity Projects”.

Hardware and Software Requirements

Graphics Requirements

  • In case of an unsupported graphics card, or forcing unsupported graphics option ( in my case by calling Unity with command line parameter ”-force-opengl” ), Unity displays the message “Unsupported graphics card. Unity Editor requires DX9 level graphics card (shader model 2.0). All graphics cards made since 2004 should be ok” and “Your graphics card is: GDI Generic”.

Legacy Hardware

  • On my legacy Win7 computer with “Athlon XP2400” CPU, 3 GB RAM, “NVIDIA GeForce 6800 GS/XT” graphics card with 512 MBytes RAM:
    • Unity 3D version 2.6.1f3 works fine.
      • After installation, Unity shows the snag screen “Unity v2.x. This version of Unity requires authorisation for use of it. Please press the 'Register' button to begin the authorization process. A one time 30-days free trial is available for everyone</del>”.
      • Indeed, free operation of Unity is offered by registration anyhow ( ”[x] Activate the free version of Unity” ).
    • Unity 3D versions 4.2, 4.15,..3.0 install, but the Unity editor crashes immediately when called, by an “APPCRASH” error message.

  • The shareware version of 3D GameStudio does not make use of models ( .mdl files ), but the current 3D GameStudio version does, indeed !
