Hello!
I recently played/streamed Doom II thru k8vavoom and had a great time! I think this port does the lighting the best. Properly clips the lights, does the overall lighting job fairly tastefully. And thankfully it doesn't make it so every surface looks wet and reflect lights =) So, thank you, past, present and future devs of (k8)vavoom!
Now, to the bugs/feature requests, ordered by importance (descending). I apologize if some of this is already known, or if I missed a setting to do what I wanted.
- Trying to start a level with Doom3 style lighting enabled crashes the game for me. First time I got some error code, next time I got a generic "k8vavoom.exe has stopped working" error. Windows 7 32-bit (Core2 Duo E7500), GeForce 9500GT (OpenGL3.3 I think, latest available nVidia drives). Windows 10 64-bit with Intel Core i5 5200U (integrated gpu) works fine.
- Turning "Infinitely tall monsters" to "on" makes it so the pick-ups are also infinitely tall. You can fly over a rad-suit to pick it up. In vanilla, you have to actually drop to the item's height first AFAIK.
- Movement physics got me completely stuck inside level geometry at least twice: first inside an alcove with radsuit in MAP15 in the first yellow-door area (to the right right after you enter that area), and second was in some secret area in MAP26. I believe running fast enough into a small gap comprised of two corners is what makes you stuck (==> you <==)
- LightAmp Colormap = Fixed Light Amplification is not working at all when the lights are completely black in the map. For example, in MAP27 after you activate the first IMP "trap" and lights go black, even with LightAmp the area is completely black, while with other Colormaps it is lit up. I think it uses multiplication, and we all know what happens when you multiply zero by anything.
- I think it is impossible to enable any kind of anti-aliasing to level geometry, or at least I failed to. In PrBoom/GlBoom (for example) setting AA in nVidia control panel actually works.
- Icon of sin now requires hitting it 9 times instead of 3. That's quite a difficulty bump...
- The skybox now warps around like a sphere to accomodate for full mouselook i presume, but the City Levels bg looks way too warped, and many people play without vertical mouselook, so it would be nice to be able to switch the skyboxes to original rendering.
- Rockets now completely disappear when fired into moving lift floor. That's especially visible in MAP30 when rockets auto-aim at enemies, the lift moves, the rocket hits the floor and just disappears. It hits the floor and explodes in the vanilla.
- Sometimes the audio stutters (both music & sfx, while the picture is perfectly fine). This might be specific to my setup tho.
- It would be very nice to have a vanilla status bar (full-width), preferably scaled to vanilla ratio (the empty sides could be filled like it's done in DOOM Retro; and would be nice to have interpolation options for the status bar, eg. integer/nearest/*linear/whatever).
- It would be nice to have the sky not affected by Invuln pickup.
- In the OG vavoom the static lights from light fixtures were not smoothed (red lights on MAP05 looked more like a cone), while in the current k8vavoom such lights are always smoothed out. Is it possible to give us some control over how much to smooth them lights? Or just a switch whether to smooth them or not?

thank you for playing k8vavoom, and especially for bug reports! i LOVE bug reports! ;-)
1. dunno, sorry. i have nVidia GT720 on GNU/Linux, and it works. i mean, this is as much testing as i can do. there may be bugs in shaders or in other code, but unless it starts crashing on my PC, it is mostly impossible to debug. sorry. anyway, shadowmaps look better, sprites can cast shadows with them, and they are much faster than D3-style shadow volume lighting. the only reason i am keeping shadow volumes is because they give a non-blurred light edges, which may be something some people prefer over shadowmap smoothing.
2. yay. thank you, will fix that! i never actually played with this option turned on. ;-)
3. this is That Fuckin' Bug. i hit it ONCE, some of my friends are able to hit it very often, and i added several workarounds to prevent it… but it is still there. and i haven't the slightest idea how it could happen. it CANNOT happen at all… but it happens. ;-) i'm still looking for the solution. the problem is that i cannot properly reproduce it, and when it happened, it is too late to analyze anything.
4. yay. yep, i believe it is multiplication. thank you, i'll take a look!
5. this is, again, something i have no idea of. the engine has its own anisotropy filter settings, but that's all. i mostly brute-forced it until it worked on my PC, and called it a day. sorry.
6. oops. tbh, i never properly finished Doom2 (i consider reaching Icon as "i win!" sutuation), and i don't even know how much one should hit it. will take a look, thank you! this is definitely some bug on my side.
7. this is something i am leaving as is as a homage to the original Vavoom. (honest answer: i am too lazy to write new sky rendering code. ;-)
8. hm. it definitely shouldn't happen. thank you, i'll take a look!
9. i have the exact opposite situation: the video stutters sometimes, but the audio don't. ;-) i am using OpenAL to play audio, so it is prolly something with OpenAL. sorry.
10. if you try to shrink the screen with "-", you'll have a status bar. i removed side fillers, tho, because i believe they look ugly. i'm not playing with status bar, though, so this code needs some love.
11. sorry, but this is not possible. pickup effects are done in post-processing shader, when everything is rendered, and applied to the whole screen area. and i cannot use stencil buffer to mask the skies, because stencil buffer is already used for decals.
12. i believe they are. every light has a falloff, and i didn't changed the falloff formula. can you post a screenshot, please?
and thank you again for your reports! i really appreciate that you registered here to give me your feedback. even if i may reject some reports, i still value all of them, and i am happy that you liked k8vavoom!
p.s.: please, note that i don't even have Windows installed. Windows binary is cross-compiled from GNU/Linux, and i usually run it with Wine to check if it starts at all, but this is as much Windows testing as i can do. it is really a miracle that it works on the real Windows OS. ;-)

(honest answer: i am too lazy to write new sky rendering code. ;-) Well there's still another way for me, which is drawing my own better skyboxes 12. i believe they are. every light has a falloff, and i didn't changed the falloff formula. can you post a screenshot, please? I'm not talking about the falloff but rather about how sharp the sides of the cones are. --- Regarding the crash on level startup.. I'll probably install Mint and try using D3 lighting again. Something's telling me it's not my hardware but Windows' fault. p.s. I probably should get at least GT720 too ha-ha

that's what you get for lightmapped mode. sorry, i haven't realised that proper lighting isn't working for you. when you wrote about "D3-style", i immediately thought about shadow volumes, and forgot that it means both shadow volumes, and shadowmaps. switch Vavoom to lightmapped mode, and you'll get exactly the same picture.
too bad that you aren't able to run k8vavoom as it intended to be run — with shadowmaps. you will not only have something like the first screenshot, but monsters will cast shadows from light sources too! and you don't need 3D models for that, sprites can cast shadows.

that's how it SHOULD look: note the shadow from Zombie! ;-)

I'm fairly certain i'll be able to reproduce that in MAP15. What can I do to be of help? sadly, not much. i need to be able to reliably rerpo it myself, so i could compile a debug build and see what's going wrong. that's what makes this bug so nasty: no way to make a stable repro case. :-((

Yeah I already saw those beautiful shadows on a newer laptop. Thanks for the screenshot, checked it on my newer machine - it indeed has sharper lights. I assumed that "D3 renderer" still used the same code for simple lightmaps but now I can see that it doesn't.
But even in "legacy" mode it is still better then most, if not all other ports IMO. Mainly because of proper light clipping. It's just that I have a pre-built PC for older mid-2000 stuff and wanted to use it for Doom as well, but alas.
Regarding that 'getting stuck' bug.. I suppose k8vavoom doesn't have any kind of DEMO support? Would be a nice way of reproducing a bug like this.
I might look into it myself but i'm kinda scared to dive into someone's source code when the project is this big

Кстати, есть ли какой свежий билд под "Шиндовс" этого года?

nope. i am working on Strife fixes yet.
p.s.: english, please. show some respect to other readers, don't force them to use google translate. even "engrish" (like mine ;-) is better than other languages.

Would be a nice way of reproducing a bug like this. k8v has demo support. but it won't be of much help: it is just a recording of network packets. and Vavoom is proper client/server system. so demo record is just a set of snapshots with entity positions, it is missing all other relevant info. so it would be "now you see me — and now i am in the wall". which i know already. ;-) that's why i need to reproduce this myself, so i can log everything and more. and i don't even know what to log yet. the biggest problem is that IT CANNOT HAPPEN. i added explicit checks to player movement code, and if the player ends up stuck, the whole move is aborted. there is no way you can go into the wall, program logic doesn't allow it. that's why i am so confused.

But even in "legacy" mode it is still better then most, if not all other ports IMO. Mainly because of proper light clipping. even in lightmapped mode the lights are dynamic (i.e. the engine recalcs lightmaps if necessary). there are also shadows from transparent textures. it is hard to notice, but you can see it in the end of E1M1. there is how it looks with shadowmaps: and this is lightmaps: you might notice that there is the same shadow from the texture, only very-very blured. ;-) also, i had converted Cheello monsters voxel pack. it looks amazing. but i don't have authors' permission to distribute it (it is heavily repacked and somewhat modified, so i don't know if i am allowed to upload it). and the feature i am most proud of (and which nobody'll notice, but it was designed this way): dead bodies will not stay suspended in the air, because hitbox corner touched some floor above. they will slide away. i.e. no mode cacodemons hanging from pillars! ;-) you may notice the effect by seeing bodies slowly sliding down the stairs. and not only bodies: pickups will slide down too. i think it is more fun this way. ;-)

From Cheello's moddb page: You may use my voxels in your own projects, as long as you give me, "Cheello" credit.
I think Cheello even stopped answering requests to reuse the work precisely because it is already stated in the "readme" that "YES YOU CAN"

the credits are there, of course. k8v even explicitly prints in the log that it is "Cheello Voxel Pack" loaded. ;-)
Init: checking digital signature... Init: PUBLIC KEY: mHYS^gckt0?f&7663u!Zz=zcNkFZPtFxEl*7Dh(4>?N^> Init: SIGNED BY: Ketmar Dark (genuine; fingerprint: 460d:0892:323a:fc41) Init: AUTHOR(S): Cheello (Daniel Peterson); Ketmar Dark (k8vavoom adaptation) Init: TITLE: Cheello's Voxel Doom v2.0, 01/08/2023; k8vavoom version 0.96
;-)
p.s.: don't be scared by "digital signatures" — there is no restriction of what you can load! ;-) they are used only to check if the package is "authentic" — i.e. created by the respective author, and not modified later. if signature check failed, k8v will still load the package.

don't force them to use google translate lol, this is exactly what I do all the time when I post on international forums "but there is a nuance..."

I've tried to load up "HFE" with "HFEG" today. Was really surprised that all worked w/o any problems. Might get some videos of "K8Vavoom" recorded in nearby future.
P.S.: If all possible problems with Cheello were settled up - where I can find this voxel pack for "K8Vavoom"?

Was really surprised that all worked w/o any problems. this is definitely a bug! there should be some problems. a lot of problems! ;-) as for Cheello… they aren't "settled" per se… but i think i can publish the pack. so i'll create the topic for it now.

so, here it is. i hope Cheello won't have anything against it. ;-)

Does K8Vavoom have a way for ACS to call VavoomC functions, as is the case for ZScript static methods with ScriptCall?
|

Post by ketmar on Apr 4, 2024 17:14:23 GMT -5
tdrr, no. the idea is that if you need to call VC code, then you'd better write your script in VC — because you had written some VC code anyway, otherwise what is there to call? ;-)

I'm gonna use ScriptCall to more or less map the ZScript API to the Zandronum ACS equivalent, so the duplicate code could be minimized. Ah well, I'll take a look at writing a VavoomC version of that at some point after release. Thanks for the info!

sorry. prolly the only thing i can do for you is add "LOADVACS" k8v-specific lump, so you could use some IFDEFs to compile two versions of ACS code. then it would be possible to use VC and k8v-specific ACS for k8vavoom.

At that point it doesn't really matter, I can use that light function you mentioned a while ago to check for K8Vavoom at runtime. Still thank you.
