I tried to build a oval track with the demo to see if I could even attempt at building anything worthwhile. I'm usually pretty good at anything graphic related since I've done a lot of sketchup and photoshop work. I found some tasks very easy and others impossible. I wasn't able to import any x-packs or add on textures or materials. And editing the track surface seemed like it was limited. I was hoping someone here could tell me if the demo was limited like this or am I too retarded to figure it out? Just trying to decide whether or not to buy the full program.
