$envmapsphere 1 breaks projectedtexture lights

[Vuthakral]

Details

Anything with $envmapshere 1 does not react to projected texture lighting, such as the player's flashlight.

Here is an example on a Half-Life 1 Gordon model I am currently working on, the grey metal regions are the only ones being altered. I have left the material for the orange bits of the suit to $envmapsphere 1 to demonstrate the consistency of all three instances.

My VMT:

"VertexLitGeneric"
{
	$basetexture	"models\vuthakral\hl1\characters\gordon_promo\gordon_promo"

	$envmap		"models\vuthakral\hl1\characters\gordon_promo\sphere_grey"
	$envmapsphere	1
}

Steps to reproduce

1. Point a projected texture light source at an object with the $envmapsphere parameter set to 1.
