[Unexpected Behavior] ActorFrameTexture's zbuffer/vertex normals behavior is incorrect.

[MrThatKid]

What you're using

I'm working with models in ActorFrameTextures, and I noticed that the way it displays is inconsistent with how it would display outside of an ActorFrameTexture. (I remember hearing something about vertex normals being inverted in AFTs)

This is replicatable in SM5.0.12, so it's an upstream bug, too.

For example, I'm going to use an audio tape model found in Puurokulho's "Private Caller" file. cassette.zip

Here's the code one would put into a layer (with the model parts in the same folder):

Def.ActorFrameTexture{
    InitCommand= function(self)
        self:SetWidth(SCREEN_WIDTH):SetHeight(SCREEN_HEIGHT)
        :EnableDepthBuffer(true):EnableAlphaBuffer(true):Create()
        help = self
    end,
    Def.ActorFrame{
        OnCommand= function(self) self:fov(60) end,
        Def.Model{
            OnCommand= function(self)
                self:zoom(1):Center():zbuffer(true):wag():addx(-160)
                :effectmagnitude(10,20,0)
                :effectclock('bgm')
                :effectperiod(10)
            end,
            Meshes= "cass_inside.txt",
            Materials= "cass_inside.txt",
            Bones= "cass_inside.txt",
        },
    }
},
Def.ActorFrame{
    OnCommand= function(self) self:fov(60) end,
    Def.Model{
        OnCommand= function(self)
            self:zoom(1):Center():zbuffer(true):wag():addx(160)
            :effectmagnitude(10,20,0)
            :effectclock('bgm')
            :effectperiod(10)
        end,
        Meshes= "cass_inside.txt",
        Materials= "cass_inside.txt",
        Bones= "cass_inside.txt",
    },
},
Def.Sprite{
    OnCommand= function(self)
        self:SetTexture(help:GetTexture()):Center()
    end,
},

Here's what it looks like: (left = AFT sprite, right = model outside of AFT)

Expected behavior

I'd expect both to look pretty similar instead of zfighting.
