I also don't see shadow maps for alpha materials, but i assume that is caused by material keywords like noshadow, backSided, DECAL_MACRO and twosided that disables shadow casting.

 

Also that shadow mapping softness at the distance is because duzenko implemented "Contact Hardening" shadows, the closer to the object, the shadow is, the harder it gets! :D sounds dirty ;p

As part of my work on a VR port, I have been spending some time looking at the Doom3 BFG edition code for opportunities to improve performance. A core concept in BFG is a vastly different vertex cache

Nothing significant. I cleaned up a few things in code, but apart from that the latest executable is still state-of-the-art   Far as I can tell, it runs pretty stable now, so from my side it could be

Can you try using a core profile GL context? It allows a more recent GLSL version on Intel (on my system).

Regret not in TDM 2.07.

Try forcing r_useGLSL 1 in game console.

Update 12 is here:

 

https://www.moddb.com/mods/the-dark-mod/downloads/tdm-206-vertex-buffer-beta

 

* A new texture atlas system for Shadow Maps significantly improves resolution management and LOD

* Improved Softening for Shadow Maps

* Almost all shadow acne has been solved and the remaining artifacts are very minimal.

 

 

Note: The softening has improved to the point that you can lower r_softShadowsQuality to 14 or lower and still

have very smooth shadow transitions in most cases.

VideoRAM increased and CPU usage too.

But a nice jump of 7-8 FPS in that scene! (15%)

Old "contact" issue with the shadowed object (there's NO contact with radius 1 too :P)

2.06 has hybrid vanilla and BFG code, with mostly vanilla code and dhewm changes.

 

2.07 will move closer to BFG.

 

We are picking and choosing the features we like from various Doom 3 (and BFG) branches and integrating them

along with our own code design changes.

Some major upheaval and improvement took place since the last update.

 

Soft Shadows now use a substantially improved PCSS calculation courtesy of stgatilov

 

Also, there is always a minimum amount of softening as a way to obscure aliasing artifacts

at the low resolution bounds of the shadow map.

 

In short, shadows are more physically correct, better looking, and almost all aliasing artifacts are

hidden.

 

Also, tentative work has been done to setup per light-entity light center size attributes so different lights can have different amounts of softening.

 

For the shadow map softness, the slider will no longer work as the override is now a negative number.

 

Recommended settings:

 

r_shadows = 2

r_testARBProgram = 1

r_softShadowsRadius = -0.65 or 1

r_shadowMapSize = 1024 or 1440

r_softShadowsQuality = 24 or greater

 

Note: You can even go lower on the Shadow Map size due to the new minimum shadow softening feature. Give it a try.

Awesome final result! NOW there are no more contact artifacts!

 

 

 

Beautiful tomb-shadowed relic projecting its own shadow on the tomb @the end :D

 

(Do shadows are clustered-calculated or per-object/mesh?)

One omni-directional shadow cubemap per light, all lights in one shadow texture - assuming you're on r_shadows 2

The ones you posted above.

 

r_shadows = 2

r_testARBProgram = 1

r_softShadowsRadius = -0.65

r_shadowMapSize = 1024

r_softShadowsQuality = 24

 

 

r_softShadowsRadius is a negative number?

 

Btw i installed duzenko latest volumetric test shaders and exe and shadow maps started working...

I don't know how to do that. Do i just delete the shaders folder?

 

C:\Users\%userprofile%\AppData\Local\AMD\DxCache

is where cache data is supposed to reside, from a little googling. Similar path for nvidia

but it's under AppData\local\Temp\Nvidia...

Not only!

 

There's AppData\local\Nvidia\GLCACHE too

      I just uploaded a new version of the Visible Player Hands mod. It's been updated for TDM 2.13 and has new animations. Check out the post if you're interested!

      I moved from Manjaro Linux (rolling release) to Linux Mint (LTS). One of the reasons was that I found the updates a bit too often and long. But now on Mint I get updates every day, although they're usually small updates.

      I'd like to track my level design progress a bit more often now, so I'm using the feed in my profile here.
      I've been working intensively on Springheel's YouTube course over the past few days. I'm currently up to lesson 8. There is so much information that needs to be processed and practiced. 
      I have started to create my own house. As I don't have the imagination to create a good floor plan, I grabbed a floor plan generator from Watabou and experimented with it. I chose a floor plan that I will modify slightly, but at least I now have an initial idea. 
      I used two guards as a measuring tape: The rooms are two guards high. It turned out that I can simply double the number of boxes in DarkRadiant in grid size 8 that are drawn in the floor plan. 
      I practiced the simplest things on the floor plan first. Drawing walls, cutting walls, inserting doors, cutting out frames, creating VisPortals, furnishing rooms.
      I have had my first success in creating a book. Creating a book was easier than I thought. I have a few ideas with books. The level I'm creating will be more or less a chill level, just for me, where I'll try out a few things. I don't have an idea for my own mission yet. I want to start small first.
      For the cellar, I wanted to have a second entrance, which should be on the outside. I'm fascinated by these basement doors from the USA, I think they're called Bilco basement doors. They are very unusual in Germany, but this type of access is sometimes used for deliveries to restaurants etc., where barrels can be rolled or lifted into the cellar. 
      I used two Hatch Doors, but they got completely disoriented after turning. I have since got them reasonably tamed. It's not perfect, but it's acceptable. 
      In the cellar today I experimented with a trap door that leads to a shaft system. The rooms aren't practically finished yet, but I want to continue working on the floor plan for now. I'll be starting on the upper floor very soon.

      Ich möchte nun mal öfters ein bisschen meinen Werdegang beim Leveldesign tracken, dazu nutze ich hier den Feed in meinem Profil.
      Ich habe mich in den vergangenen Tagen intensiv mit dem Youtube-Kurs von Springheel beschäftigt. Aktuell bin ich bis zu Lektion 8 gekommen. Das sind so viele Informationen, die erstmal verarbeitet werden wollen und trainiert werden wollen. 

      Ich habe mich daran gemacht, ein eigenes Haus zu erstellen. Da mir die Fantasie fehlt, einen guten Raumplan zu erstellen, habe ich mir einen Grundrissgenerator von Watabou geschnappt und damit experimentiert. Ich habe mich für einen Grundriss entschieden, den ich noch leicht abwandeln werde, aber zumindest habe ich nun eine erste Idee. 

      Als Maßband habe ich zwei Wächter genommen: Die Räume sind zwei Wächter hoch. Es hat sich herausgestellt, dass ich in DarkRadiant in Gittergröße 8 einfach die doppelte Anzahl an Kästchen übernehmen kann, die im Grundriss eingezeichnet sind. 

      Ich habe bei dem Grundriss erstmal die einfachsten Sachen geübt. Wände ziehen, Wände zerschneiden, Türen einsetzen, Zargen herausschneiden, VisPortals erstellen, Räume einrichten.

      Ich habe erste Erfolge mit einem Buch gehabt. Das Erstellen eines Buchs ging leichter als gedacht. Ich habe ein paar Ideen mit Bücher. Das Level, das ich gerade erstelle, wird mehr oder weniger ein Chill-Level, einfach nur für mich, bei dem ich ein paar Sachen ausprobieren werde. Ich habe noch keine Idee für eine eigene Mission. Ich möchte erst einmal klein anfangen.

      Beim Keller wollte ich gerne einen zweiten Zugang haben, der sich außen befinden soll. Mich faszinieren diese Kellertüren aus den USA, Bilco basement doors heißen die, glaube ich. Diese sind in Deutschland sehr unüblich, diese Art von Zugängen gibt es aber manchmal zur Anlieferung bei Restaurants etc., wo Fässer dann in den Keller gerollt oder gehoben werden können. 
      Ich habe zwei Hatch Doors verwendet, die allerdings nach dem Drehen vollkommen aus dem Ruder liefen. Inzwischen habe ich sie einigermaßen gebändigt bekommen. Es ist nicht perfekt, aber annehmbar. 
      Im Keller habe ich heute mit einer Falltür experimentiert, die zu einem Schachtsystem führt. Die Räume sind noch quasi nicht eingerichtet, aber ich möchte erstmal am Grundriss weiterarbeiten. In Kürze fange ich das Obergeschoss an.

      On a lighter note, thanks to my cat-like reflexes, my superior puzzle skills and my perfect memory, I was able to beat the remastered version of "Tomb Raider: The Last Revelation" in a new superhuman record time of 23 h : 35 m, worship me!
