My answer was for the simple question of setting fog values via an external(.cfg) file, now I see your problem! 

i have a map with a worldspawn settings something like
fog_density x
fog_colour x y z

and after loading this map in AD the fog appears correctly, then i put the very same map in the id1/maps folder and run it from the vanilla game
there's no fog at all
until i manually set the fog numbers in the console, what gives? 

those are AD-specific fog keys.
Try: "fog" "density r g b" 

"fog" "Density R G B"

All on one line for stock id? 

Try: "fog" "density r g b"

i put this line fog 0.015 0.35 0 0
into an *cfg file without the quotes, but no avail. 

Sorry, put it in worldspawn, not a cfg file :) i.e. the worldpawn key is "fog" and the value is "0.015 0.35 0 0" 

yay, it's working this way. silly me. Thank you Eric and damage_inc 

Hey, I require help
Whenever I try to launch any of those 2 executables using:
./mark_v_linux or ./mark_v_winquake_linux
I get following error:
bash: ./mark_v_winquake_linux: Permission denied
Double-clicking doesn't work either

On manjaro, hope anyone can help 

chmod +x mark_v_winquake_linux
Has done the trick for me, it works now! 

I was playing back some demos of Spy's work-in-progress map in 1.36 and the final frames of the imp fireball (the impact only) show up as non-transparent. If this is not a known issue, or repeatable I can try a screencap to make this a bit more clear. Works fine in other engines. Notably Quakespasm-admod 

I've ran into this.

Which sprites are you using?

Kinn original: uses black for transparency requires enfine with support for .png override textures (e.g. Darkplaces) and additive mode.
AD: Not sure.
Keep: I converted all mine to use pink transparency for full support on all engines. 

It's actually an older map of Spy's that he's working on getting ready to release pretty soon. Not sure what assets he was using.

@Spy are you using the same assets from the original Bastion/Marcher maps? 

Mark_V enables external textures by default, so set external_extures to 0 and reload the map

or just delete all of *.tga files from the sprites folder, they are absolete now 

Mark V's adaptive FOV calculation method seems to be quite different from QuakeSpasm and original FitzQuake. I need to increase FOV by about 6 to get the same field of view as in QS (using a 16:9 display). Of note, QS just does vert- when you set scr_sbaralpha 1, while Mark V does hor+. Not sure which method is preferable, however, it's possible that Baker based his adaptive FOV calculation on specific scr_sbaralpha and viewsize values. In particular, setting scr_sbaralpha 1 and viewsize 100 gives about the same FOV as in QS with full screen view point (that is scr_sbaralpha 0). But nowadays most people are probably playing with the transparent HUD, so this just results in smaller FOV. 

I have finally come across a solution to my problem. It turns out that I actually didn't have pak1 and pak0.pak. I thought I did, but I didn't check my ID1 folder. Long story short, I found something which contained both pak files and copied them over.

I love it. It runs like a charm:

I'm so sorry for wasting your time over such a dumb mistake of mine.

Missing PAK files was the problem?

How does that happen? If I remove my PAK files and try to run Mark V, I immediately get a popup error message saying it can't find the pak files.....

Maybe corrupt pak files? 

@killpixel
My laptop is 10 years old, I'd rather not...
Also, it's my first time using this sourceport, so I haven't tweaked all of the settings yet. Though, I'd love that to change. :)

@Gunter
Funny thing is, there were no .pak files at all in my ID1 folder.
The .pak files' contents were actually extracted to my ID1 folder, but the .paks themselves weren't there. Interesting. 

Interesting! You may have found "an issue."

I tested with unpacked pak files, and Mark V does indeed just crash without any meaningful error message.

These alternate engines I tested work just fine with unpacked pak files:

fitzquake 0.85
DirectQ
fteqw

Unpacked pak files should be an acceptable setup... so... Mark V should be able to handle that.




Anyway, if you're interested in tweaking Mark V with all kinds of setting which make it look better (in my view), I have a page with downloads and settings to alter: http://www.fvfonline.com/fitzquake.php

Then come play FvF :D

Any interest in bumping Mark V's limits to make it Sepulcher-capable? cf. comments 1661/1662 above.

Also, can anyone say "sepulcher-capable" five times fast? 

@Johnny - Some day ... whenever I do the next version of Mark V, which doesn't feel soon. 

And just when I finished compiling a nice list of bug reports and suggestions. Disappointing.
