Shadow Mapping in Source

[Gamerman12]

Could you inquire a little bit more on that? I've tried some solutions, mostly relating to the renderparam's in popgbuffer, popcomposite, etc. but this is what happened...

[joe_dirt976]

so is there anyway to make this into an additive shader to lightmapping? (IE projected texture style)The shadows and lighting are great, but the ambient lighting has no occlusion. I simply ask because i know very little of how this works and am still trying to figure it out. Also, wouldn't it be cheaper budget wise to use the 2 methods of lighting interchangeably? I mean using env_light for pure ambient lighting and light_spots where a deferred light would simply be unnecessary.

Gamerman12, did you also replicate the stuff in pushgbuffer for the gbuffer, because it apparently draws the gbuffer output to your backbuffer.

joe_dirt976, you would rather add the lightmapping back to the composite pass (like mentioned some pages earlier), it doesn't really make sense the other way around I guess. The highest additional performance cost is simply the re-rendering of the scene, but that can't be omitted because that's just how deferred lighting works.

The viewmodel stuff should be working now:



I didn't update the build yet, but you merely have to get my new viewrender_deferred.cpp for your own mod.

Oh man, those view model shadows. You sly dog, you.

EDIT: Oh okay, nevermind. It didn't copy over the file the first time it seems. Everything is fine and dandy now

Whenever I compile maps with the new light entities I get this in the compile log (VRAD spews it).

Code: Select all

unsupported light entity: "light_deferred_global"
unsupported light entity: "light_deferred"
unsupported light entity: "light_deferred"
unsupported light entity: "light_deferred"

What glaringly obvious thing did I miss?

Nothing, VRAD is just dumb and goes like:

'If entity name begins with light_ try to do light stuff and complain for no reason if entity is actually unknown after all'

So how involved would it be to implement this into a Source 2007 mod, assuming the person handling the code is by no stretch of the imagination a coder? Myself, to be precise, though I don't ask from the position of complete ignorance (ie I have 2007 Base code, the compiler, as well as knowing how to distribute coded changes with the mod). Thus far I've just implemented a lot of community code fixes from the VDC wiki and the like, and I've no qualms with asking for pointers and numerous stupid questions. In any case, my mod is sufficiently a ways off to accommodate a lot of broken eggs in the process (doubtful anything of it will be seen before year's end, and that's being optimistic). I realize I'm hypothesizing on a Frankenstein's baby here, but no harm in asking!

Yeah, for a non-coder, this wouldn't be easy to port. Though, I don't know how easy it would be for a good coder... Since I'm in between the two skill levels.

[-=Biohazard=-]

I know about a few people who tried it and gave up really fast, maybe because they have been spammed with errors after copy and pasting it...

Like Gary said, non-coders would probably have trouble with this - you need to understand the compiler errors you'd get if you want to fix them.

But anyway, this should be super simple to port imho. Especially considering that the materialsystem is based on the 2007 one. If that wasn't the case, there'd be a high potential for a lot of shader work to do...

Regarding the shader stuff, take the vanilla shaderlib.lib from 2007 and the keep the rest. Any compile errors should be simple to fix. For the client/server you can keep all the files and simply fix any occuring errors except for viewrender_deferred.cpp. That file is entirely different and it would make more sense to take the 2007 viewrender file and re-implement the deferred stuff, diff viewrender_deferred with the swarm viewrender file to do so efficiently.

I'm getting some really odd effects using this. The shadows are terrible.






Especially the fog acts up.

Care to give some more information? Because something is apparently broken.

It would especially be interesting to know if my build works on your hardware or not, make sure to grab the newest one...

Hey,Face Animation is crashed the game.
Models with face animation just need recompiled?

Which model have you been using? Does it work with the normal renderer?

The morph stuff is taken from 2007, it might just not be compatible like that. Run in debug mode to figure out where it crashes.

[ScarT]

Turns out I forgot to merge over some stuff in the materialsystem folder, and that caused that bug. Your build was fine, but your test map in my build was having the bug too. All fixed now

It works just fine on my hardware. I'm putting together a benchmark sometime soon to see how well it runs on various hardware.
