CreateMaterial() won't work with PNG's

[OneCoolDude]

I am trying to create materials with CreateMaterial.

Here is my code: https://pastebin.com/cC38kPQ2

For some reason, it just returns a material that is completely white.

Can anyone tell me what I'm doing wrong?

I can create the materials with the passed path completely fine with Material(). Just not CreateMaterial for some reason.

local function createKitMaterial(path, name)
    local mat = Material(path)

    return CreateMaterial(name, "UnlitGeneric", {
        ["$basetexture"] = mat:GetTexture("$basetexture"),
    })
end
This should work. If you try to make a material from a .png you need to call it with Material first.

[OneCoolDude]

The Material is already called first, that's the only reason that :GetTexture() is able to be attached to it in the first place.
But just in case, I tried it your way, didn't work.

It probably is a problem with transparency or whatever, basically you might need to set additional .vmt parameters based on what image your are loading.

[OneCoolDude]

It doesn't seem to be. I had another image that worked normal for Sneaky, but not for me. It was also a white square. But I did have another PNG which did work.

It seems random.

Nothing I can do or tell without the image files (one that works, one that doesn't) and the code, including both loading and drawing the image on screen.

[OneCoolDude]

Here are the images. I put them in a zip file because I'm not sure if image hosts change the file when it's uploaded.

Layer1 works, assaultkit doesn't.

This is the code.

[Lua] local proxy = { local _mat = Material("assaultkit.png") ..

[SneakySquid]

That code would just error, can you post what you actually used?

[OneCoolDude]

Oh lol, I messed it up. The code I had was actually correct, I just had to retype it in pastebin to show what I had.

There you go :-)

Please read my post in its entirety. Also your file doesn't work.

shouldn't it be something like this:
local function createKitMaterial(path, name)
    local mat = Material(path)

    return CreateMaterial(name, "UnlitGeneric", {
        ["$basetexture"] = "!" .. mat:GetName(),
    })
end

since the wiki says "To retrieve a Lua material created with CreateMaterial, just prepend a "!" to the material name."
Material

[OneCoolDude]

That's not how it works....

[cptn.sheep]

fair, i just saw that in the wiki but wasnt sure if you actually needed it

[Rubat]

First of all, what is wrong with using Material() function itself? Why do you need to use CreateMaterial()?

Secondly, as I have said, you will need extra parameters just to get transparency and equal functionality to Material()

local function createKitMaterial(path, name)

local params = {
["$basetexture"] = Material( path ):GetTexture( "$basetexture" ):GetName(),
["$vertexalpha"] = 1,
["$vertexcolor"] = 1,
}

local mat = CreateMaterial( name, "UnlitGeneric", params )
return mat
end

local mat = createKitMaterial( "assaultkit.png", "pointless_shit" )
local mat2 = Material( "assaultkit.png" )

hook.Add( "HUDPaint", "HUDPaint_DrawABox", function()
surface.SetMaterial( mat )
surface.SetDrawColor( 255, 255, 255, 255 )
surface.DrawTexturedRect( 50, 50, 128, 128 )
end )
Thirdly, you need to set $basetexture to a string as shown on the example for CreateMaterial() on the wiki.

[OneCoolDude]

Using GetName just makes it go purple and black, you think I haven't tried that?

I need to make the image glow, and I need VertexLitGeneric to do that.

[Rubat]

The code I posted works just by copy pasting. You cannot use vertexlitgeneric for HUD elements, its for models.
