Bravo Sergio ! I can not stop driving the track, The terrain, the road, the vegetation, presented objects, physical mesh everything is really good. You are really going for this track, I'm definitelly going to buy full package, because it is just simply awesome !
I really like how you managed the colors, and fixed wrong trees ilumination, which was there in the past.
What can I give you for feedback ? At this moment there is nothing big to care about, and I think you can just carry on. Though some little stuff could be tweaked IMO
1. Sandy hills has these grass patches, but they looks like dots, not really natural, make a bit more natural patches, IDK if it was growing in nice circles. But overall terrain is beautiful.
2. Tires skid marks and groove texture looks a bit messy to me. Not sure about the groove, but skidmarks looks a bit blurred out, while they should have sharper edges.
3. Tarmac texture and shading is beautiful, but I think it has a bit too much shining, tarmac can be so shiny when it is wet, or even blinding shiny of course, IDK, I'd tone down the shine just by very little.
4. Move hotlap spawning point further back, so it would be possible to start first lap full speed.
Impressive stuff !
