Ac3d knife1/28/2024 It is possible to export SketchUp models with single faces by using a new version of the exporter (adapted by VicMar & i4dnf). This affects fps (frames per second) and is particularly noticeable when entering an area which is heavily inhabited with buildings/models. Though there is nothing wrong with double sided faces, there is a considerable saving in FG processing if single faces can be used. SketchUp models which are completed using the existing SketchUp to AC3D exporter are rendered in FlightGear with double sided faces. Conversion of latitude and longitude locations.SketchUp has very limited material controls, so manual editing may be required. Material properties are guessed, so may appear different from Blender defaults.Texture scaling on the model may appear wrong, further testing required.The current progress as of 12 September 2008 is: The script is still in development at the moment. Failure to use a unique texture in these cases will result in your object not showing in FlightGear. xml file animates it (as with some lighting effects) - in that case you MUST use a unique texture. An exception to this method exists where you want your object to be invisible until the. When you are modelling in SketchUp and you want to ensure that you can identify one part of it later in the AC file, simply give it a unique color or texture that is not used anywhere else in the AC file. (Or, of course, you can refer to the object "blah", if this is the only object with that name in the AC file.) Only after renaming the object you will be able to address it from the XML file. The object name is the important thing for reference from XML. The name of the material does not matter at all, it could be anything. The SketchUp to AC3D exporter will give you this: Yet you will still have to rename the object. The name and the texture filename will appear in the AC file. Imagine that we use the texture roof1.png and that we name the texture Roof. Note: When you define a new texture in SketchUp, you can give it a name. So now that we have named it Roof we can refer to it from the XML file. Let's imagine that we know that it is a roof. It is this one:Īs you can see, mat 2 is used in this object. Now we will look for the object further below in the AC file that uses mat 2. Every material is given a number, starting from the first material after material "default": This means that you only have to know which material an object uses to find it in the body of the AC file. Here is how you can find an object you are looking for: Every part of the model with a unique material is defined as a new OBJECT poly. Unfortunately, when using SketchUp, the SketchUp to AC3D exporter will name every object the same: See also AC files: Textures and SketchUp: Correct display of texture colors in the AC file. One free program capable of this conversion is ImageMagick. So if you have a texture in a format other than PNG, you'll have to transform it into PNG. That means that for FlightGear to be able to display your model correctly, you will have to provide your textures in the. The AC3D exporter is set to export textures to the PNG format by standard. dae files, meaning no conversions are necessary if texturing in AC3D. Note In Sketchup 8, users are able to export as a. Then restart SketchUp and the script should be visible through the via Plugins → Export to AC3D, or Extensions → Export to AC3D in SketchUp 2015 or later. Then, follow the extension installation instuctions here. Rotate the model or switch to 'walking mode' for Quake-style control.You can download the script from this link.
