I did delete the ugly trees from the track (Circuit d'Ajaccio) completly by adding this line to the ext_config.ini:ditto - felt the same way upon testing it... the track layout is of good quality though, just like other works produced thus far. there's definitely room for further improvements to come.
MESHES = terrain_?_SUB?
LIT_MULT = 1
That way the trees will be identified as spectators and can be turned on/off via track adjustments in CSP:
The track looks very empty now but IMHO still better than with these "Picasso-trees"
