Broken Engineer Brundle Bundle

[Malevolence.]

The models for each part of the Brundle Bundle have something wrong with them. For the Buzz Killer (head), only the eyes appear. With the Legend of Bugfoot (feet) and the Frontier Flyboy (wings), they have broken cubemaps. I tried to search on the internet, but I couldn't find any help. The Engineer model is the HWM version. Can you help me fix this please? I want to make a new Chrome start tab image.

Try a different map.

That didn't work. I guess this is Valve's fault. :(
EDIT: Restarting my project file fixed it partly. The feet are fixed, and so is the head, but the wings are still broken.

Have you manually updated your sfm's tf2 files?

[Malevolence.]

Yeah

Actually, I opened up the console, and it spammed "***** Trying to set a pixel shader that failed loading!"

It's probably using a shader sfm doesn't like. Can you post the vmt?

[Malevolence.]

Sure. Though you might not need all the files, I have all of the Brundle Bundle model and texture files here: https://drive.google.com/open?id=1QUafuqi9oXvik-FI4p6YO8SXo-m0e8Kx

You can try messing with the hats vmt--- you can open it in any notepad program. Just keep a copy, in case you mess it up. I'll look at it more later, but I gtg for a few. In the meantime, try this in the hat vmt:

"VertexlitGeneric"
{
	"$baseTexture" "models/player/items/engineer/hwn_engineer_hat"
	"$detail" "effects/tiledfire/fireLayeredSlowTiled512.vtf"	
	"$detailscale" "5"
	"$detailblendfactor" .01
	"$detailblendmode" 6
	"$yellow" "0"

	"$phong" "1"
	"$phongexponent" "4"
	"$phongboost" ".5"
	"$lightwarptexture" "models/player/demo/hwn_demo_lightwarp"	
	"$phongfresnelranges" "[.25 .5 1]"
	"$phongwarptexture" "models/player/items/engineer/hwn_engineer_warp"
	"$basemapalphaphongmask" "1"


	// Rim lighting parameters
	"$rimlight" "1"												// To enable rim lighting (requires phong)
	"$rimlightexponent" ".5"										// Exponent for phong component of rim lighting	
	"$rimlightboost" ".5"										// Boost for ambient cube component of rim lighting
	
	}

The texture is still wrong, but at least it's not glowing anymore.

Just checked mine, and they loaded just fine, without any visual error. I used a custom map-- try loading them on stage.bsp.
