I’m trying Sketchup Pro 2017 but I have a problem. First I was working in sketchup 2018 and made a house in it. But Sketchup 2018 was also a trial and when this trial was over, I continued working at the same project in skecthup pro 2017. Everything in 2018 was fine untill I began to work in 2017. It looks the same in 2017 as it was in 2018 but when I want to render my model, my materials does not appear in the viewport. I’ve tries everything but I don’t know what to do anymore 'cause everything looks the same accept that when I open the vray asset editor, my material list is empty.
Please can anyone help me?
