How to make breakable glass?

So Iv been fiddling around with vtf edit and GCFscape to find out how how to make a custom glass texture that works with Func_breakable_surf. When im in vtf edit iv seen a few options when i click the auto vmt. The options consist of Base texture 1, Bump map 1, Base texture 2, Bump map 2, Environment, Environment mask, Detail texture, Tool texture, Normal map, Dudv map. If anyone knows how I can create a custom texture that works with Func_breakable_surf it will be greatly appreciated.

reading https://developer.valvesoftware.com/wiki/Func_breakable_surf and then looking at the .vmt of glass/glasswindowbreak070a


 "LightmappedGeneric"
{
	"$basetexture" "Glass/glasswindowbreak070a"
	"$envmap" "env_cubemap"
	"$surfaceprop" "glass"
	"%keywords" "c17industrial,bms"
	"$envmapmask" "glass/glasswindowbreak070a_mask"
	"$envmaptint" "[1 1 1]"
//	"$envmapsphere" 1
	"$translucent" 1
	"$nocull" 1
	"$crackmaterial" "glass/glasswindowbreak070b"
} 

you should beable to make a custom one :slight_smile:

Thank you so much and it worked like a gem
