Dont have the code rn since i deleted but i remember it.
local function convert(chunk)
local instances = chunk.instances
for i,v in pairs(instances) do
if v.Name == "Wedge" then
workspace.Terrain:FillBlock(v.CFrame,v.Size,Enum.Material.Grass)
v:Destroy()
table.remove(instances,i)
end
end
end
Idk if the table.remove thing worked but whatever
You don’t need table.remove for this
original code didn’t have it, it still didn’t work sadly 
Are you sure instances is an array of part already?
Yeah, instances are an array of parts, also i checked if its named “Wedges” since trees are also stored there.
The string you specified is “Wedge” though
I didnt rename the Wedges, idk why i put it in quotation
Its still named “Wedge”
Can you try print(instances) before the for loop and screenshot the output table expanded?
Studio crashed but whatever
Also ill show u what it looks like
It literally just makes no parts at all when i remove “table.remove”
I printed v.CFrame and v.Size
--CFrame \/--
772.5, -16.9695091, 765, -0.17906189, 0.684085429, 0.707081199, 0.969490528, 0.244981378, 0.00850054342, -0.167406663, 0.687030613, -0.707081199
--Size \/--
0.0010000000474974513, 10.939990997314453, 10.629768371582031
It is a possibility that the thickness of these are a bit too small for an actual terrain to be made
Try set the X axis size to 1 to see if it works
OOH I’VE DONE THIS BEFORE lemme see if I can find the code…
I mean yeah prob, should i add to size? Like 10 every axis?
Alr
Try just 1 on the slim axis, the X
It worked but like:
You see the dots or is it just me?
snippet from some code of mine, where w1 and w2 are wedges, hopefully you can adapt it
if TERRAIN then
local success, err = pcall(function()
if value.water then
Terrain:FillWedge(w1.CFrame,w1.Size+Vector3.new(5,4,4),Enum.Material.Water)
Terrain:FillWedge(w2.CFrame,w2.Size+Vector3.new(5,4,4),Enum.Material.Water)
elseif value.coast then
Terrain:FillWedge(w1.CFrame,w1.Size+Vector3.new(5,4,4),Enum.Material.Sand)
Terrain:FillWedge(w2.CFrame,w2.Size+Vector3.new(5,4,4),Enum.Material.Sand)
else
Terrain:FillWedge(w1.CFrame,w1.Size+Vector3.new(5,4,4),Enum.Material.Grass)
Terrain:FillWedge(w2.CFrame,w2.Size+Vector3.new(5,4,4),Enum.Material.Grass)
end
end)
end
the reason i added extra values to the size vectors was to reduce dots/holes like you’ve seen already, assuming those holes arise by the same reason
Oops, perhaps the triangles are simply too small or something? I’m really not sure what’d cause that 
Maybe ill try changing some values… Im gonna test if it works normally without convert underwater too, maybe its just the code
Works good without the convert function
Yep changed values worked perfectly!
v.Size+Vector3.new(20,20,20)
Hi do you know if there’s a script I can put in the command bar to turn parts that are named a certain thing to terrain? Like “Grass Block” and turn it into roblox terrain grass?
