The thread title says it all. Does anyone know how to use propper to make glass. The vmt still had the (keyvalue [Is that what its called]) alpha 0.5 but the surface was now opaque. For now I just have the glass part as brushes but its kinda annoying me. Does anyone know how to remedy this? Also I don't know why it optimized the model so strangely but I'm just rolling with it. Also rolling with the fact it says the model is 64.5 units when its actually 64 units.
