@@Novastar.SaberCombat NO WAY.....You're not going to believe this but just in the last two weeks I was thinking about Darkhell, it was one of the very first custom WADS I ever played in '95/'96and it left an impression on me. I was 15 at the time and going by memory I fondly remember the level with the wide upwards spiral, the HUGE wide open 3rd level and the tower level that was an actual tower. I remember the huge open circular level making my 486sx25 struggle even with 8 megs of RAM. Blakhell doesn't sound familiar but I'm going to see if I recognize it. Thank you for creating something that became a happy memory for me. To this day I still play DOOM/DOOM2 on a CRT. DOOM shaped who I am today.

The original Doom could possibly be considered the high point of gaming and artwork, considering how much it's still played and referenced and modded.

Just to point out, Voxel Doom will also work with any WADs that only use sprites from Doom 1. So for example SIGIL will work with this perfectly as it only uses Doom 1 assets.

[@metalvideos1961]

you can run it wih doom 2 mods as well. its just that not all Doom 2 monsters are modeled yet. so if you see a revenant for example you will see it as standard 2D. but if you see a shotgun guy you will see it as the Voxel. just a mix from both.

[@johnclark926]

@@thiagovidal6137 that’s cool to hear. I’ve been fearing that combining Voxel Doom + path tracing would result in the voxels being shaded instead of flat/no shading, which would imbalance the 3D and 2D aspects and result in the voxel models looking like Minecraft constructions, but hearing that the mid developers in communication with one another makes me hopeful that they can find a compromise.

[@SimonBuchanNz]

It's a weird case, as you need to throw out all the self shadowing and lighting information, any simulation of shine, etc, and just flat shade everything perfectly lit, and then add other layers of material info, normally roughness and metalicity. The extra quirk is that you also need normals, and that's not free when you're using voxels: it's possible it's easier to recreate the models traditionally then voxelize the information!

[@CreateConsumeRepeat]

Amazing job. Voxel Doom looks insane. I would kill to see this with ray tracing.

[@KillahMate]

Actually part of why the voxel models look so 'correct' is because there is no lighting applied so they fully match the original sprites. Doom is too old for ray tracing - it was basically a 2D game with some rendering tricks and art direction to make it look 3D. Quake 1 is at least fully 3D and was built with a _sort of_ realistic light propagation so maybe diffuse ray tracing would make sense, but Doom would need to be completely rebuilt and in the end it wouldn't look very much like Doom anymore.

[@cannonaire]

@@KillahMate Digital Foundry made a video on a ray traced version of Doom. I think that if that version used these sprites it would take it to another level.

[@Wobbothe3rd]

Yes, it's unfortunate that the RT Doom is in PrBoom, a different sourceport, so there's no easy way to combine the two... yet.

[@MikkoRantalainen]

As a software programmer, the 3D rendering and voxel rendering in this port is nice but the true hero is Daniel re-drawing original graphics in voxel format. That's insanely hard task and he even made sure that the original 8 directions look correct for the whole animation loop! That probably required lots of artistic freedom because the original sprites were not 3D rendered but human drawn sprites. You cannot perfectly blend those into a 3d model directly.

[@KingSigy]

I love voxels anyway, but what really sold me on this mod is how the animations are handled. At times, I thought I wasn't even playing a mod. It captures the essence of Doom's art style so perfectly.

[@BlueMaxxW]

This is the best graphics mod for Doom I have seen since the source code released. I have wanted something like this for decades and they nailed it.... NAILED IT!

[@VincentFischer]

The vertical aim is not "an assumption". The engine is unable to have two "things" in the vertical plane. There will always only be one thing vertically you can hit, so no need to assume anything.

[@SmogginMog]

Yeah his surface level knowledge of Doom is slightly painful.

[@bauul.]

I'm not sure what you mean by "vertical plane", but you can have multiple targets all within the the same vertical slice of the screen. Imagine standing at the bottom of a flight of stairs and each step has a monster on. All of them are valid vertical targets. Doom's auto-aim is pretty basic though: it targets the enemy physically closest to the player. However, because the horizontal spread of the auto-aim is quite wide (~6 degrees) you can be aiming directly at a more distant monster and have the auto-aim lock onto an enemy closer to you that's a little off to the side. That's what DF meant about it being less than helpful sometimes.

[@VincentFischer]

@@bauul. Because I was unsure of dooms coordinate system (is the Up vector on Y or Z) I tried to circumvent that distinction by saying vertical plane. You can't have multiple entities in the same place "on the ground" just with height differences. What you are describing are entities with completely different coordinates (not just the height) so this is not the situation we are talking about. In your case it will always shoot the entity more close to you. The engine has no concept of up/down, everything is in a 2d coordinate system. the height differences are just an "optical trick" (that's why the doom engine is sometimes referred to as 2.5D engine)

[@Wobbothe3rd]

@@VincentFischer That's not exactly correct, but close. Carmack recently clarified exactly this point in his recent interview. Y values are stored in Doom's engine (ie a Cacodemon coming down, or the position of floors like a staircase), and like Bauul said above Doom's auto-aim essentially just chooses the closest target, which is sometimes a faulty assumption.

This is sooo cool! Imagine doing this with Daggerfall Unity! The 'paper cut out' feel to NPCs feels increasingly out of place as the rest of the world gets upgraded.

[@the1ucidone]

This is phenomenal! What an absolutely amazing modification. Kudos to the modder for his unbelievable creation and talent.

1:53 The reason it shoots below or above you, is because Doom technically is a 2D game -- height/elevation is just trickery. It's the same reason why you cannot have rooms/corridors stacked vertically over one another. Or why you cannot stand on top of or jump over the head of enemies below you. If you open the minimap in Doom, what you're seeing is something more truthful to how the Doom game engine actually operates -- in 2D.

[@bauul.]

There are always a few people who pop up on Doom videos spouting stuff like "Doom is really 2D" with absolute confidence, when it's objectively not true (mostly because they watched an ill-informed Game Theory video from years ago). Yes, Doom has limitations on the height axis, but no, this doesn't mean it's a 2D game. Those things you mentioned are not "the reason" why Doom is 2D, they're the small number of limitations on the Z height axis which stop it being (arguably) "full" 3D. But that's not the same as it suddenly being entirely 2D. All the ways in which it is properly 3D (full 3D positions for all entities, full 3D movement within the game space, proper gravity implementation, independent height values for all surfaces, full 3D line-of-sight checks, etc. etc.) don't suddenly stop applying just because there's a couple of places in the code where the Z axis is ignored.

@@bauul. Then make me a WAD with vertically stacked rooms, and also please add perspective correct rendering while looking up and down. I'll wait. PS. I don't know Game Theory, but the "Make Your Own Raycaster" series by 3DSage is my preferred demonstration of raycaster engine limitations.

[@bauul.]

@@FM-kl7oc The lack of vertically stacked rooms is one of the specific limitations of the Z-axis I talked about. The other is solid Thing collisions. These two things alone do not make Doom a 2D game. The incorrect perspective rendering (Y-shearing) is also not a limitation of the engine's third axis, that's simply an issue with any software rendering. The Build engine had the same problem. However, the fact you seem to think the Doom engine is a raycasting engine might explain your confusion. It's not, you're thinking of the Wolfenstein 3D engine. The Doom engine (aka idtech1) is a BSP engine, which allows for much greater 3D geometry than a basic raycaster.

[@Wobbothe3rd]

Doom engine does keep track of a Y-axis for certain things. Just because you can't build a room over a room doesn't mean there's no y-axis AT ALL or the game would be much less interesting, like Wolfenstein3D.

[@RealBadGaming52]

@@bauul.u may be right, in GZDoom u can jump over gaps , im assuming that would be impossible in 2D

[@mptest7461]

I also love how animation is improved while preserving the original look and feel. Looks better than some attempts of making 3d models in Doom. Great job!

[@AfterBurnerTeirusu]

Having an option to look up and down in DooM is pretty cursed. Not as bad as jumping, but it's extra work for an already smooth experience.

[@Wobbothe3rd]

You can choose not to, that's already a feature of GZdoom, but you can turn it off. Obviously you wamt that feature to show that the mod actually works in this case, but you can play without 6dof mouselook just fine.

[@AfterBurnerTeirusu]

@@Wobbothe3rd True

[@CodingWithUnity]

Never had 3d graphics explained in such detail. I fully understand the difference between 2D and 3D now

[@RQUKOfficial]

Just need some enterprising modders to make this work with Brutal Doom. I imagine that'll be a lot of work though.

[@guillermo9171]

I thought the same but BD has too huge an amount of new sprites and animations. To the point that it would probably take more work to just voxelize BD assets than the entirety of vanilla Doom

[@luigimaster111]

I'd love for the view models of the weapons to be modeled as well, and an option to alter the view model positioning. I want to see what Doom would look like with the weapons placed on the left side like in contemporary fps titles, and I wanna see how that weapon bobbing looks in 3d.

[@Somewhere_sometime_somehow]

Yeah, this is greqt, but the weapons look seriously flat now

[@karloz2722]

I subscribed to Cheello's channel long time ago because I really appreciate the work and effort he puts on this. I think he nailed the balance between updating Doom and keeping what made Doom special in the first place.

[@zipobob1]

Is it possible to combine this with Doom ray tracing upgrade?

[@skullthrower8904]

Imagine a nuts map with this lmao Thx for shining light on this project and the creator he really deserves it

[@RyanCoomer]

at a buffet, i personally sneak corndogs into the buffet so others can enjoy them. I hide 6 corndogs in my jacket pockets. it then, is a joy for me to see other patrons of the establishment eat my corndogs thinking they were part of the buffet.

[@RGSPro]

This mod is super incredible. When you're looking at the moving enemies you can't really tell a difference when you're using the voxels until they are dead and you can examine them. They are that accurate to the original sprites. I really love how accurate these voxels are to the original sprites. The biggest change is seeing the flat item sprites rotating in 3D like the guns, ammo, and health crates. Can't wait to use it on Doom Retro, my favorite source port.

[@KoeiNL]

The weird thing about Doom is that I mainly remember all the sound effects and not really anything gameplay related :D

[@proesterchen]

This is awesome! Thanks for covering this mod, Alex! 👍

[@fmsyntheses]

The idea that people play Doom with mouselook is highly disturbing to me.
