you can only mask's and content enums
but what you can do is filter out props using filter in the trace structure
https://wiki.garrysmod.com/page/Structures/Trace
what you can do is just check the model name using https://wiki.garrysmod.com/page/Entity/GetModel
then filter it out
or some shitCode:local los = {} -- other shit los.filter = function( ent ) if ( ent:GetModel() == "modelorsomething" ) then return false else return true end
