This mod adds various street trash like in GTA 4. All trash appears randomly in places where pedestrians walk. There is a slight division into areas, for example, in business areas there will often be various leaflets and newspapers, and in the ghetto there will often be alcohol bottles and cigarette butts. In the .ini file you can configure the garbage intensity, radius and spawn frequency.
Thanks for the advice and test vladvo, InsertNamere, Mouhamme_Taher.
