According to official IBL Standard Shader definition, there is a "Receive Shadows" option (under General Configuration) in material editor which can be Enable or Disable: https://docs.studio-397.com/develop...a-guide-in-rfactor2/pbr-using-standard-shader But this option is not presented in current version of material editor. I'd like to know if there is a way to set this option to disable. So far I have found a few json files that contains "RECEIVESHADOWS":"@Null", line, tried to add it to json but does not work. It would be great help if it can be done. Thanks!
