FWsim allows you to create your own 3D worlds, with 3D models that you find on the internet. You can launch the world editor via the “Tools” menu in the FWsim main window.
Here, you can import and arrange your 3D models.
To find your own 3D models, we recommend you start your search at 3D warehouse. If you work on commercial projects with FWsim, good news: 3D Warehouse has a very generous license, so you might be able to use those 3D models in your commercial projects free of charge. (Please make sure you check the license yourself before using any models).
To import a 3D model, click “Add” and then “Import”. FWsim supports a wide variety of file formats. You can use model files directly, or import ZIP archives containing your model. If your 3D model does not work, please send it to us and we will help you out.
Here, you can change the settings for your show.
You can enable or disable the display of lines. Many 3D models on the internet contain both solid objects and lines. Sometimes these lines are an important part of the model (for example, they might represent power lines, ropes or cables). But often, these lines are a visual distraction and the object looks better without. Starting in FWsim 3.1.1, the display of lines is disabled by default.
You also have the option of changing the ground texture. If you want to add your own ground textures, please open your FWsim installation directory (normally at c:\program files (x86)\fwsim). Look for the folder “Resources” and then “ground_textures”. You can add your own ground textures here. Make sure your texture is quadratic and no bigger than 4096x4096 pixels. You can use JPG, PNG or DDS files - but the file ending must always be “.dds”. So, for example you might want to use your own file called “my_ground_texture.jpg”. Simply rename it to “my_ground_texture.dds”, and put it into that folder. Then, re-start FWsim, and you can now select your texture from the list.
The ground texture is stored per 3D world, however, the sky background is stored as part of the show file and can be changed by clicking Show → Scenery in the main window.
