A model that will appear after a certain amount of time?

I'm making a model so the model will appear like after 15 sec ur in a game This is my script

Wait (20)
Local game.workspace.transparency (1)
Local game.workspace.CanCollide = false
wait (30)
Local game.workspace.transparency (0)
Local game.workspace.Cancollide = true

you are making the whole workspace transparent try like this

	Wait (20)
	Local game.workspace.ModelName.transparency (1)
	Local game.workspace.ModelName.CanCollide = false
	wait (30)
	Local game.workspace.ModelName.transparency (0)
	Local game.workspace.ModelName.Cancollide = true

and probably you can't set a model transparency/CanCollide so, modify the part, like that

	Wait (20)
	Local game.workspace.ModelName.PartName.transparency (1)
	Local game.workspace.ModelName.PartName.CanCollide = false
	wait (30)
	Local game.workspace.ModelName.PartName.transparency (0)
	Local game.workspace.ModelName.PartName.Cancollide = true

also if you have many parts and it take you too long, try to make it into mesh, build your thing in blender, import the FBX into roblox as a mesh then put the mesh in the model

	Wait (20)
	Local game.workspace.ModelName.Mesh.transparency (1)
	Local game.workspace.ModelName.Mesh.CanCollide = false
	wait (30)
	Local game.workspace.ModelName.Mesh.transparency (0)
	Local game.workspace.ModelName.Mesh.Cancollide = true

anyway, if you want, you don't need to put the mesh in model, if is like that, just remove "ModelName"

	Wait (20)
	Local game.workspace.Mesh.transparency (1)
	Local game.workspace.Mesh.CanCollide = false
	wait (30)
	Local game.workspace.Mesh.transparency (0)
	Local game.workspace.Mesh.Cancollide = true
