PointShop Trails Help

I am not the best at lua, but I can’t seem to figure out what the problem here is.

I tried adding new trails to my PointShop. In this case I used “nature/inftreec” for the material for my trail. When I bought it, it crashed my game. No error messages. Nothing, then every time I tried to join back, it would crash my game again as soon as I got on the server.
The only sort of error is from the console which says:

This is my current code for the trail, if it helps.

ITEM.Name = 'Tree Trail'
ITEM.Price = 200
ITEM.Material = 'nature/inftreec'

function ITEM:OnEquip(ply, modifications)
	ply.TreeTrail = util.SpriteTrail(ply, 0, modifications.color, false, 15, 1, 4, 0.125, self.Material)

function ITEM:OnHolster(ply)

function ITEM:Modify(modifications)
	PS:ShowColorChooser(self, modifications)

function ITEM:OnModify(ply, modifications)
	self:OnEquip(ply, modifications)

Thanks. Any help will help me out, as I am not the best at lua. But I try :stuck_out_tongue:

Your first fault is that you don’t have an extension on the material name. Put nature/inftreec.vmt, also are you sure that this is an actual trail you can use.

Is this a trail you’ve made yourself or an already existing gmod material?
