True, it could also be from playing an old mod. 

The .paks are from my CD. Someone else told me about the .pak thing today elsewhere. The weird thing is the same using the same .paks in MarkV doesn't give me this problem. 

MarkV can add "previous weapon" (impulse 12) even if the mod doesn't have it / you are not running the latest patch version of the pak0.pak/pak1.pak. 

Replace pak0.pak (the one that's the same in shareware and regular Quake) in your Quake directory with the latest version (1.06, available here) and you should be good.

Pak1.pak shouldn't need to be updated to the best of my knowledge. 

It was indeed the pak0.pak. Man, my CD must be old. 

Collectible! :-) 

0.93 "has stopped working" when trying to load death32c.bsp 

reproduced it. 

64-bit builds (tested on windows, probably linux/mac also) have a bug where the player gets stuck on buttons that move at an angle:
https://sourceforge.net/p/quakespasm/bugs/26/

I don't have a fix yet, but it's 99% likely the same as past 64-bit bugs (code assuming x87 math with 80-bit temporaries for floats) and should be quick to fix.

We'll do a 0.93.1 bugfix release sometime soon with this, a fog bug fix - https://sourceforge.net/p/quakespasm/bugs/24/ , and the death32c.bsp crash (vis data overflow). 

 

Do you know if any engines with fence textures implement it?
I'm assuming it would just need to use (0.666 * entity_alpha) as the alpha mask cutoff, instead of always using 0.666? 

Currently you can have a func_illusionary using a fence texture and set the alpha to any value between 0.666 and 1.0, but below that it just dissappears.

I think it is just an arbitrary hardcoded threshhold. If it is necessary to have a threshhold, having it at 0.09 would be preferable. I haven't done an engine comparison for it.

Could be the thresshold has something to do with support for alpha channels (e.g. on png) instead of just the pink palette value 255, but not really sure on that point. 

My understanding is, the 0.666 threshold only comes into play when you use texture filtering - the actual pixels of the fence texture only have alpha of 0 or 1, the texture filtering interpolates between these, and then the fragment shader converts the interpolated value back to 0 or 1, depending on whether it's less than the threshold or not. So the specific threshold will control how big the fringe is around spites / fences.

The "(0.666 * entity_alpha)" sounds right to me, it's just something that should have a test map + screenshots, maybe with 0.25, 0.5, 0.75, 1.0 entity alpha on a fence texture. 

Lower alpha values will cause edges of fences to become faded, blurry or hazy, which is a very undesirable artefact. If you want to achieve a specific effect it's better to open a discussion about it, rather than trying to overload an existing effect in unintended ways. 

I am trying QuakeSpasm with a Dualshock 4v2 connected to Steam Link (so it appears as an xinput device to the game, afaik). The controller works, but there is a very odd problem: there is seeminly no way to "enter" any menu. I can enter/exit the main menu, navigate it, but not actually enter any of the menu options with any gamepad buttons.

And a feature request if I may: would it be possible to add an in-game mod and map browser/launcher?

Suggestion:implement Quakeworld style HUD option from this branch. 

I enthusiastically second this idea. Even if it's just a console cmd and not in the menu I prefer this HUD to NQ version. 

Please see this: http://www.quaketastic.com/files/misc/testing/test_trans.jpeg

I had the idea one day to mix alpha and {fence to make ground fog. It looks neat in the editor, but it doesn't work in-game. It would be really cool to mix this type of effect with some non-solid func_train's, func_bob's, etc.

I still don't understand why it doesn't work below 0.666.

Cross Engine Testing:
FTE: Does not support alpha on {fence textured faces. Side note: fence rendering has weird ugly black edges.
Mark V: Same as QS. Side note: the Pixelated/Rough mode looks best for fence edges (not related to the alpha). Not sure if this is just disabling mipmapping or what.
DarkPlaces: The old version I have doesn't support either {fence or alpha.
All other engine versions are the most current. 

I can enter/exit the main menu, navigate it, but not actually enter any of the menu options with any gamepad buttons.

The A and B buttons are hardcoded to select menu items / go back a screen. If A/B are not working, it means something failed at a lower level than Quakespasm (probably SDL2's controller mapping).

Does it help if you download this file and put it in your quake directory?
https://github.com/gabomdq/SDL_GameControllerDB/raw/master/gamecontrollerdb.txt
It should enable more controllers.

re: mod menu and bangstk's changes, both things I have been meaning to get to 

I still don't understand why it doesn't work below 0.666.

Because GLQuake sets this at startup:

<p>glAlphaFunc(GL_GREATER, 0.666);</p>

Meaning that when the alpha test stage is enabled, anything with an alpha of less than 0.666 is discarded.

Fences are drawn with alpha test enabled, so that's why it doesn't work. 

Is there still use for the SDL1 version? Just curious about why that variant is still included in the package. 

Not much significant - audio CD support, win 9x support. 

Hey Eric. I periodically update through your nightly builds page found here:

(http://quakespasm.ericwa.com/job/quakespasm-sdl2/)

but the page has been giving a 502 error. Just thought I'd let you know in case you were unaware. :)
