Shadow Mapping in Source

[Gary]

I still can't seem to go any higher then 1024....

[Bites]

Absolutely no idea, then. 1/4 Life is currently working on a fixed up clientshadowmgr.cpp with a ton of fixes like attenuation and stuff, + the ability to change the shadowmap resolution. I'll ask him if he's alright with me sharing, but I can't promise anything! We might have to save it for when a little mod me and MaxOfS2D are working on with some of his buddies as well.

Uh, that would be really nice just for a community release. All mods could benefit from good env_projectedtexture stuff...

[Bites]

Yeah I know, I'll ask him if I can release it. But again, that's his decision, not mine!

[Gary]

Well, we can always hope. The community would be greatly thankful.

[Dabu]

Well, Portal 2'll have significantly improved projectedtextures. I don't know if it's worth working right now.

[Gary]

I will only wait till then if I know for a fact that they will release it's code with it.

[Gary]

Really, it's not of high quality by any standard, but Smurf wanted to test it out so I uploaded. Since it's already uploaded, you guys can try it out. Not really that exciting, just some stuff I was messing around with. Really, this is missing a few fixes from the VDC, so it's not going to run the best.

Just type "map" in console to see the maps I complied for this.

r_flashlightdepthres is the shadow map resolution, it doesn't appear able to go over the view point's resolution.
You must set r_flashlightscissor to 0 to prevent clipping! This will be hardcoded in future versions!


Here are some pictures of one of the HL2 levels I recompiled for fun, it has a few graphical glitches, but the last few lights look quite awesome. There is about 6 or 7 in the level. Far more optimization needs to be done.









It's about 8MB, 48MB uncompressed.

That doesn't look awful, I might try it when I head home...

Is it just the client and server dlls or does it include the code?

[Gary]

I suppose I could release the code, but I have step by step instructions on the front page.


Also, that download is the testbed I am working on. It includes a few maps and the client and server dlls. I hope to release a far more optimized and better looking version within the next couple weeks. This was just what I had at the moment Smurf wanted to try it out.

[Gary]

Misread VDC, to fix clipping, set r_flashlightscissor to 0. This will be hard coded in future versions.

1: Will this code be usable in mods with your permission?

2: Does it work with static_prop_polys?

3: Can you make it look less sketchy? i.e. pic 2

Why do you need permission? I figured this stuff out by scouring the wiki and found the env_projectedtextures/fixes page. The least you need to do is just thank gary for solving the grain issue, though Mr2 had a helping hand in solving it too.

it's incredibly simple fixes tbh, just a few lines a code change.
Except the r_flashlightscissors 0 command isnt hard coded in yet, which means you need to enter it into the console every time you run the mod if you want overlapping dynamic lights

Of course you can use it, I did this for the community.

2: Does it work with static_prop_polys?

The command line option for VRAD? I don't see why it would interfere with it.

3: Can you make it look less sketchy? i.e. pic 2

Lower the jitter I suppose, but lowering it too much with make the edges blocky.

[Gary]

Also, I plan on redoing the first part of the first level of HL2. Designing it a bit to show of dynamic lighting.

I will release that in a few days.
