There have been a few threads asking how to change driving-line (aid) texture. Here is a method (workaround) for customizing driving-line texture. The idea is to create a new DrivingLine_Alba.dds texture file and packaged into track layout mas file. Since track layout mas file has higher assets loading priority, new driving-line texture will override built-in texture from game. Example texture ZIP file is attached at the end of post. Steps: 1. Create a new texture, size 512x512 or 1024x1024 should be enough. 2. Create a new empty layer with alpha channel. 3. Draw a new shape that represent driving-line, and fill it with pure white. 4. (Optional)Apply slightly "Gaussian Blur" to the shape so the edges won't be too sharp. It will look like following: 5. Export image as TGA format and name it DrivingLine_Alba, and use MapConverter tool (in rFactor 2\Support\Tools\MapConverter folder) to convert texture to DDS format. See dev guide for how to use MapConverter. 6. Place new DrivingLine_Alba.dds inside the track's layout folder (as unpacked from mas file). 7. Use MAS2 tool to either create a new track package, or a track update package. Then install and play in normal game. For how to create track update package, see guide here. Arrow style: Line style:
