Hi Arno, I am trying to add props to the default hovercraft, both static and rotating. The textures are there, but the props are not included in the model. I am not too sure where to start here. It is strange that they did the textures but not the animations in the mdl file. The prop textures are not in the mdl file either. The Boat is SimObjects/Boats/VEH_water_hovercraft01_sm. I have done the spray effects and sound, just need the props now. Thank you, Charlie.
