Last week version v0.6 was released, but a small patch was needed to fix some bugs. Get the full 0.6.0.1 or patch here. Note: You need to register at Bob's Track Builder's website to download the demo. Known Issues: No SObjects appearing in existing projects. You need to copy the XPack from the BobsTrackBuilder\XPacks folder to the project under the BobsTrackBuilder\MyProjects\[YOURPROJECT]XPacks\ folder. XPacks are not automatically updated in case a non-BTB created XPack breaks compatability. Some Objects only appearring from certain angles in rFactor. The addition of Single-sided materials means an improvement in speed and reduced flickering on textures such as billboards. However, you will need to update your Materials for an existing project. Fistly copy any of the BTB-created XPacks into your project. Secondly, flag any further materials as double-sided where required.
