So, I finally decided to change to 3DS Max, and it was like a new beginning for me, so I don't really know how to do things there yet.
I can say that 3DS Max is so much better than blender. Quality is much better, cars don't look plastic, rendering time is like 7min, but blender use to take ~20h.
I was just trying to make one render, to see how it looks. I hate the chrome rims though and I didn't know how to fix them...
BTW, if I want to take or change some parts of the car, I have to select the part by vertices or something? Because the FXO was like one piece all together and I couldn't select just rims, it would select the whole car. Or maybe I was doing something wrong...
