Anyway... I think I will reinstal it later when I will wake up, now I will go to sleep.And for the future I will know to back-up all the files for every update.
But if you still want to investigate, I'm not rushing and I can keep it like this a bit more. I will check the replies here if you need any other files to check out.And I still ow a video that I made and I need to link in the "importer" topic, that is about the spinning wheels animation and physics, they spin on all axis depending on the geometrical shape and position of the tire objects.I have no idea what is happening there, if anyone can share some insight about any "tricks" why are the tire objects from the imported object behaving differently depending on coordinates of the objects within the imported object.
And what key is it again to start record and stop recording the videos?(Or I'l look for the page with some basic guiding, I think I saw a topic about video recording in Outerra). Anyway I used Camtasia cause I heard that I need to convert the video and other things to get it for a proper format on YouYTube, but the problem was after I made the video... it looked very lagged and low fps, even if when I was recording nothing seemed to be going wrong.
