How can you make a lua trigger a mesh change?

How do you make a lua trigger that when entered, changes a mesh dae, and when exited it stays like that?

 

I don't know how to do that, but you can try setting transparency (alpha) to 0 for one mesh and to 1 for another. Here's code (assuming you already set transparency of the second mesh to 0):

Code:

local function meshAlpha(data)
   if data.event == 'enter' then
      for i=1, #core_vehicle_manager.getPlayerVehicleData().vdata.flexbodies do

         local name = core_vehicle_manager.getPlayerVehicleData().vdata.flexbodies[i]["mesh"]

         if string.find(name, "meshName1") then
            be:getPlayerVehicle(0):setMeshAlpha(0, name, false)
         end
     
         if string.find(name, "meshName2") then
            be:getPlayerVehicle(0):setMeshAlpha(1, name, false)
         end
      end
   end
end

meshAlpha

Instead of "meshName1" and "meshName2" use your flexbody names
