Amazing work and thank you so much! you make the circuits look so much more alive! And I know this is not going to be the last version.
But are the 3D trees also meant for the new GT version from Nuvolari? It is just an other layout, not a different mod. The trees look good but some trees take too long to appear (noticed a big one at the hairpin and a couple smaller further away) and I also get some weird shadows about 2-3 metres from the ground after the Spoon towards the 130R.
Just go to the assettocorsa-rootfolder: content --> tracks --> rt_suzuka --> extension and open "ext_config.ini".
There you find [TREES] as the 2nd section directly under [MODEL REPLACEMENT]. Just rename "trees.txt" behind "LIST_0 =" into "trees_ReworkedOak.txt" or "trees_Birches.txt". Especially the last one should give you some FPS back, but it doesn't have the variety of trees. Maybe in the summer I'll have another look into it for more and different performance packs.
