Testers and reviewers wanted: BFG-style vertex cache

[Baal]

I am currently testing the latest SVN build (7702) on an Intel Celeron notebook running Archlinux and the latest Mesa drivers. Lighting does not work at all, only ambient. Should this work or is that just the current state?

Any errors in console? Could be GLSL compiler issues.

with this settings

 

r_testARBPrograms 1
r_shadows 2
r_softShadowsQuality 32
r_softShadowsRadius 5 // this controls shadow blurriness and at 11 like i add before it can cause shadows to almost disappear.
r_shadowMapSize 1024

 

Shadow maps look good enough to me and performance is much better, where i add 26fps before now i got 55+fps.

 

Btw I forgot to test this right now but i think you guys need to debug changing shadows at run time, on my last test when changing from stencil to shadow maps, some shadows vanished, perhaps caused by the high r_softShadowsRadius, but when returning to stencil, r_shadows 1, those shadows didn't return?! Perhaps it didn't changed to stencil like it was supposed to and i thought it did? But if so that would mean r_shadows 1 didn't worked.

That would be great of course. Right now you need to quick save/load after shadow switch. A known issue.

Ok

[peter_spy]

Btw. by shadow maps you mean this? https://cloud.githubusercontent.com/assets/1278614/2939606/1b1f033a-d951-11e3-9ceb-d6e9849b9f7d.png

 

I can make a fence material with alphatest and the light behind it will cast proper shadow?

Yes, even though it wouldn't work with stencil.

[peter_spy]

What must I enable to test shadow maps? I made an alphatest fence, similar to what's in the picture, but when I use r_shadows 2, all shadows disappear.

Do lights render if you set r_useGLSL 0 and r_softShadowsQuality 0 ?

[Baal]

Yes, but not correctly.

 

Do you use OpenGL's debug output feature (the KHR_DEBUG extension)?

Quick save/load

 

Yes, but not correctly.

Not ATM.

Try deleting your darkmod.cfg.

 

 

Yes, but not correctly.

Did 2.06 work on your system?

[Baal]

Did 2.06 work on your system?

Yes. But soft shadows do not.

Quick save/load

 

 

Didn't work on my system. Are there any mandatory cvars or GPU drivers I need to use? (nvidia GTX 1060 here, driver version 398.36, win 7).

Does the volumetric build also fail to show shadow maps? If so, try clearing your darkmod.cfg

[peter_spy]

Using the volumetric build:

 

1) I deleted the darkmod.cfg, ran the game, set the resolution to 1440p / windowed, restarted the game

2) I launched the volumetric test map, entered r_shadows 2 in the console

3) Pressed Quicksave (F4) and Quickload (F9)

 

All shadows are gone, only the projection texture works.

[duzenko]

This is what I get.

It could easily be an nvidia compatibility issue, even though it was supposed to be fixed before the last alpha build.

The volumetric build could be based on an earlier svn version, so you can also try the same recreated darkmod.cfg with the last build @nbohr1more posted - that should work (even if it won't).

 

EDIT. I can confirm that the volumetric build seems like to be incompatible with nvidia implementation of GL_TEXTURE_COMPARE_MODE. The nbohr1more's build is supposed to work.

[peter_spy]

Okay, I used the update 11 build instead of volumetric and deleted volumetric keyword from light materials to make them work. I see the pixelated shadows in the first example, but that alcove window on the right (alphatest plane) doesn't show any shadows.

 

Edit: that said, the shadow mapping works nice with higher values. I set the soft shadows quality to high, radius to 5 and map size to 2048, and it looks good.

Then it must be something in your old .cfg that prevents the shadow maps to show?

[peter_spy]

No idea, I only have this in my autocommands.cfg:

 

com_allowConsole "1"
con_noprint "0"
set g_fov "85"

r_postprocess_bloomIntensity "1"
r_postprocess_bloomKernelSize ".5"

 

Also, maybe I'm misunderstanding something, does having shadow maps equals having transparency shadow maps?

Yes, it should work like on the right picture.

I'm talking about darkmod.cfg, not the autocommands.cfg

[peter_spy]

Here it is: https://we.tl/t-S0p31RXHj7

[peter_spy]

A quick comparison. Both shadow modes have quality set to very high and radius to 5.

 

Soft stencil shadows:

 

Shadowmaps with shadowmap size 1024:

 

Shadow maps fare better, because they get more blurred with the distance, although maybe they could have some better filtering. 1024 px shadow maps can look quite pixelated, 2048 px looks better. Still can't get the transparency shadow maps to work though.

Oh, the hard-contact (in the second picture)
