Prop with texture that has alpha channel (In this case we'll be using a fence model)įirst of all, go into notepad and copy this Orangebox /Source 2009 Engine Game (Half-Life 2 Episode 2 or Left 4 Dead) These shadows are lightmap shadows, so they cannot be moved and thus, are static.īut if you're using a static prop you shouldn't care anyways.Īnyways, you may be wondering "Alright, this sounds cool, how do I accomplish this?". This is better than before, but there are still some flaws. This command, combined with -StaticPropPolys, can allow your alpha channels to create shadows. Skip forward to now, where we have learned that the light compiler (vrad) now has an option to allow the alpha channel to allow light through. Yes, they were dynamic (And partially better than what i'm about to teach you about), but they are really bad looking. Then came the Orangebox engine, and at first, we could use projectedtextures to create our dynamic lights, but then nVidia complained about the shadows from these entities and resulted in nVidia users getting these nasty grainy-edged shadows. Nobody ever wanted to do this because it was pointless and very time consuming (And the shadows looked blocky) In the days of the HL2 Source engine and the HL2:EP1 engine you had to make a grating yourself, by taking a blocklight texture and cutting it out. This would be okay, but it looks really unrealistic when a light is near it. This is great for visual looks like looking through it, but source has no idea what to do about lighting for the alpha channel for props, and it simply uses the collision model as a shadow reference. The fence's grating has an alpha channel that allows you to see through it. For example, glass textures have an alpha channel that makes them transparent. You may be wondering "What does alpha mean?" Alpha - or more specifically the alpha channel, is what defines transparency in an image.
