Play in option shows nothing. Impossible to start any wad

Linzino — Tue, 27 Jan 2026 00:20:28 +0000

I get select a folder with wads (master levels from Steam, doom1+doom2 from Steam, etc.).
I see a partial list (20 items) with wads.
If I click on a wad I see "Play in". Clicking on Play in has no effect.
My user/password cannot be used to report a bug. So I am stuck.

The Future Of Doomsday Engine

wyland — Thu, 11 Aug 2022 11:11:58 +0000

since the last Doomsday build released in August 2021, it seems that not much has happened concerning a new build.
I would really appreciate a statement telling us the status quo of the Doomsday Engine.
Thank you very much!

How to Jump

Pretty much what it says. Where's the key I use to jump? Or, how do I assign a key to Jump, preferably up...

How to Fix FOV and Weapons Cut Off

laxdragon — Thu, 26 Apr 2018 03:11:24 +0000

This took me a bit to track down, but I use an ultrawide monitor with a 21:9 aspect ratio, and the FOV is wrong at 95. It needs to be wider to look correct. Not only that, but using weapon models the weapons are cut off on the bottom on the screen. To fix, change your configs at:

C:\Users\\AppData\Local\Deng Team\Doomsday Engine\runtime\configs\\game.cfg

Find and change the following:

# Field of view.
rend-camera-fov 137

# When FOV > 90 player weapon is shifted downward.
rend-hud-fov-shift 0

Hope this helps anyone else with this issue. I think this could be fixed in engine, by adding options in the GUI for these two options, or better yet, automatically change the FOV for different aspect ratios.

Blasphemer and Zauberer support

M_S — Sat, 21 Jun 2025 15:56:57 +0000

Hello, I know that the main developers of DE aren't working on it for now, but once they come back I'd like to see support for these two games on the launcher.
They are basically the Libre equivalents of Heretic and Hexen, I tried to rename their files to see if I could make the engine think they are the original ones, but it doesn't work.

Fix for crash when no gamepads are connected

thesourcehim — Sat, 27 Apr 2024 09:44:50 +0000

I recently upgraded to Fedora 40 and 2.3.2-build3869 started to crash when trying to start any game.
For anyone who experience this here's the fix (you'll have to build from source):
Open file doomsday/apps/client/src/unix/joystick.cpp
At the line 236 you'll see: return SDL_JoystickName(joy);
Replace this line with these:
if(joy)
return SDL_JoystickName(joy);
return "";
Then rebuild.

Grayscale Spectres (partially invisible pinky demons)

Makaki — Sat, 25 Jan 2020 06:37:38 +0000

Have you ever tried applying a grayscale filter to the Spectres, before the alpha channel change?

As I understand it, right now you use the same texture as the pinky Demons and adjust the alpha channel. But I think removing the color saturation entirely and going grayscale would make them harder to see and more in line with the original look and feel. This could be a game option (or just console variable).

As for coding the grayscale funcion in C, no idea. I was thinking of making a fork to try it out, but I think it's above my programming pay grade. I did find that there are various algorithms to convert to grayscale, with different "visual" results:

http://www.tannerhelland.com/3643/grayscale-image-algorithm-vb6/

So would be interesting to see which one fits the Spectre better. (ignore the vb6 tho)

This would apply to any other partially invisible enemies in Heretic/Hexen? but idk, I don't play those. I guess it would apply to Marines in multiplayer if they pick the power-up.

Changing Computers

fizixx — Sun, 09 Jun 2024 15:23:08 +0000

May be going from Win 10 to Win 11.

Is there a way to port my existing (2.3.1 Build 3685) setup (DOOM, Plutonia, Nostalgia, etc) to the new computer, or does this all have to be redone from scratch?

What is Snowberry?

Mighty_Lu_Bu — Mon, 19 Aug 2024 19:43:12 +0000

Isn't this part of the Doomsday launcher? The reason I ask is because some Doomsday engine mods say to add to the Snowberry folder, but I do not have one.

Voxels - how feasible?

HiPhish — Thu, 12 Dec 2013 01:57:00 +0000

Hello guys

I have been playing Doom and its related games for the first time recently and I have enjoyed Doomsday Engine enormously, and if there is one feature I would love to see added it would be voxels. I have to say I can't stand the look of modern lighting and 3D models in Doom, but I think that the voxel project captures the aesthetic of the 2D sprites perfectly.

I took a look at the issue and from what I have gathered the engine would need to turn the voxel information into a mesh to display with OpenGL. I know that the Polymost renderer by Ken Silverman for Duke Nukem 3D is OpenGL accelerated and supports voxels (there is a voxel pack for Duke 3D as well), so it is possible to display voxels, the question is "how". From what I understand the voxel information needs to be used to build a 3D mesh that can then be used like any other 3D model mesh, and since Doomsday already supports 3D models the meshing itself is the tricky part.

I have found two articles on that topic:
http://0fps.wordpress.com/2012/06/30/me ... raft-game/
http://0fps.wordpress.com/2012/07/07/me ... ft-part-2/

The article discusses four algorithms. The first one is pure brute force, each voxel becomes a cube (six quads) and the second one uses occlusion to hide voxels on the inside, both algorithms are not very good.
The third one is no more than factor 8 times worse than the best possible mesh, it uses a greedy sweepline algorithm to find the smallest mesh in each dimension, reducing the one 3D problem to three 2D problems. The results are pretty good and it still uses quads. The fourth algorithm (second article) uses polygon triangulation, so there are no quads. If that's a good thing or a bad one I can't say. There is also a web demo to compare algorithms:
http://mikolalysenko.github.io/MinecraftMeshes2/

The next problem is the texture. The way it's solved in the article is to simply treat each colour as its own voxel model, but then the mesh will have more faces than it would if everything had the same colour. The voxels from the voxel pack make heavy use of dithering, just like the sprites did, so this would yield results similar to the brute force algorithm. A better idea would be to treat the voxel model as one shape and then use the result to somehow construct a texture that's then applied to the mesh.

What do you guys think?

Does anyone know where and how to get and play Heretic 2?

Thank you

Sigil very poor FPS on E5M6

redlid — Sat, 01 Jun 2019 10:21:55 +0000

On this level and on this cyberdemon maze my FPS got single digits and it's unplayable. What's going on?

2.1.1 stable
core i7 3.7ghz lynnfield
r9 fury

Should not be PC being shitty as it's plenty of enough for Doom, 3D-accelerated or not.

No anti-aliasing/trilingual filtering possible?

Tormentor667 — Sun, 09 Oct 2022 15:51:30 +0000

Dear members and developers,

is there a way to deactivate any kind of trill linear/bilinear filtering and anti-aliasing for graphics, textures and sprites? I really like the pixelated look of Doom but I can’t find a way to activate this in Doomsday.

Doomsday for Android?

mikegonzalez2k — Sun, 03 Apr 2022 02:39:41 +0000

Is there plans for or a current WIP for Doomsday on Android?
I would love to play Doom on my tablet when traveling.

I was on 3685 and tried to update and it said I was on the newest update. I updated manually to 3862 no problem. Now it says i'm on the newest update but 3864 is out there.

How do I set Doomsday to render classic, non-smooth depth shadows?

Searinox — Wed, 23 Jun 2021 14:27:35 +0000

By default Doomsday appears to be doing a smooth gradient of shading. For example if looking down a dark corridor, the progressive darkness is entirely smooth. Originally Doom's shading was choppy, with fewer gradients and noticeable boundaries on the walls, floor, and ceiling. Is it possible to set this mode back in Doomsday?

So, what comes next?

wyland — Wed, 07 Apr 2021 10:33:20 +0000

Any news concerning the next generation of Doomsday?
What is planned and what will it be like?
Or is the whole project on hold because of corona?
A short overview would be much appreciated.
Thank you very much!

How I change the game data file of each game profile?

aor000 — Fri, 12 Mar 2021 09:58:34 +0000

Hello:
I don't know if this is the board for this question so admins please move it if it is not.
Anyway, I've done some map edits in doom2.wad using Doom Builder 2 and also deleted some sound clips from doom2.wad, plutonia.wad and tnt.wad using Slade.
Despite this, Doomsday preferring the original unedited IWAD file, even if it have a different name like DOOM2 original.wad, and that the modified IWAD have the official name like DOOM2.wad.
How I change the IWAD in the profiles of Doomsday Engine, so that it would be the edited IWAD?

Changing the setting of server-game-mod-gravity

Nagilum — Tue, 09 Mar 2021 20:47:46 +0000

Hi there,

is it normal or intended that I can change the value of "server-game-mod-gravity" within a multiplayer game? When I do join a multiplayer game (i.e. "Reborn, Ultimate Doom / vandalfsen.me") I can change this value for myself.

So if I change the value of this variable to let us say "1" I almost fly through the maps or if I run downstairs. Why is it possible to change this value as it might be used for cheating? Or is there is a switch or parameter to disable this behavior when I host my own multiplayer game?

Doomsdays is so amazing it's hard to go back to GZDoom

Magmarock — Thu, 11 Feb 2021 17:19:12 +0000

I'm finding it hard to go back to GZDoom despite all the mod support. It's just that Doomsday is so much more polished and vanilla friendly. Also I can't explain why but DD seems to have a better lighting system than GZD. I tried to replicate it but I just can't get anything to GZD to look as good as DD

is there a list of compatabile mods that work under doomsday?

Doommarine117 — Thu, 18 Feb 2021 00:57:22 +0000

will mods like alien eradication trilogy, castlevania simon destiny, wolfenstein 3d afadoomer, alien vendetta, duke nukem weapons an monsters mod, halo operation lone wolf an etc will work?

i see when adding the mods folder it crashes. so im guessing one of the mods is unavailable for doomsday.

How do I map for this engine?

blueinferno776 — Mon, 15 Feb 2021 20:56:35 +0000

Gzdoom already has all the modding love it can ask for. I really have no idea how to build maps exclusively for DE at all, I somewhat can write ded's for mapinfo. I know next to nothing how to map for this port, I need help to get started

The elephant in the room. Doomsday's biggest issue. [Mods]

ThermalLance — Wed, 22 Jan 2020 03:00:43 +0000

While this is my favourite port for vanilla... There is one huge issue that should be addressed at some point. Mods compatibility.

Even VANILLA compatible mods don't even work properly. For example REKKR wich seems to work but the main menu and sound effects are completely bonkers. Even older wolfendoom mods struggles at time with glitched enemies. Some mods refuses to even run...

So here is some throwaway suggestions:

- Work on mod compatibility so it can, at the very least, run mods that are known to be vanilla compatible.

- Curate mods and have a list of mods that works available from your website. Users could be the one doing it so your input would be minimal.

This engine looks very nice out of the box and I love it. I used jDoom way back in the early 2000s even before Snowberry was a thing. I must say that I am disapointed that so little has been done in regard to mods compatibility over the years.

Feature request walk run toggle rebind

Magmarock — Mon, 08 Feb 2021 13:39:13 +0000

Perhaps I missed it, but I can't find any way to rebind the walk run key (caps lock) Normally I like to use shift for that.

Feature request on jumping

Magmarock — Sat, 06 Feb 2021 02:09:04 +0000

I think Doomsday really is the best source port for playing Doom engine games vanilla.

Sometimes I forget which games you are supposed to be able to jump in, so I would like to request a feature.

A warning text that appears next to the setting “Allow jumping” to remind players that this can break the games puzzles.

That’s it. A clear notice so you know what games you’re supposed to be able to jump in.
