Just skybox support.

None of the FitzQuake/Quakespasm family of engines loads actual replacements for the 256x128 scrolling sky textures. DarkPlaces is the only engine I know offering the ability to replace the scrolling sky with a hi-res version.

[FitzQuake/Quakespasm don't + won't support PNG, just like Q3 doesn't support PNG.] 

Extra info: PNG serves no purpose for replacement textures because when the set is compressed into a .zip file, it gets compressed. The only thing PNG does is require the engine to increase map load times by decompressing the textures every single time. 

TGA already have alpha channel, so screw PNG :)
Your skybox works neat, just tested it. So, screw iD's moving PCX. 

I checked the vs2008 build in the 20141010 package again and noticed that liquids look fine again on my nvidia card if you use r_oldwater "1".

Dunno if that helps with solving the problem - still waiting and hoping for a fixed release. 

Interesting, thanks for info. Could be involved in this somehow. 

Anyone with sky issue (NVidia only) will still have sky issue. Still working on that as I do not have a Nvidia card available. And does not yet have the DX improvements.

This is a much nicer release than the previous one, but more to go.

The WinQuake version should work and these are proper builds. The glow textures should work.

New feature: Select text using SHIFT in the console and copy, cut and paste with CTRL+X, CTRL+V, CTRL+C, SHIFT+INS, SHIFT+DEL

More versions will follow as I eliminate the known issues. Next one might not be until Monday or Tuesday. 

How does the sky look with r_oldwater 0 and r_oldwater 1?

Does the sky look correct with r_oldwater 1?
Does the sky look wrong with r_oldwater 0? 

also do you get any issues with "r_oldwater 0" with Fiitzquake 0.85 or Quakespasm? 

@ericw -- any oldwater problems in Mark V wouldn't be inherited from Fitz, but something I introduced.

r_oldwater 0 as you no doubt know requires a bit of hand-holding (in the code) because it is ingenious evil render-to-texture trick. Likely, video mode change isn't updating it or I'm clearing (or not clearing) a buffer at the wrong time or not updating the texture at the right time.

Probably a simple oversight on my part.

Source for Beta 2 which is easy to build (compiles out of the box with a key press) for Visual Studio 2008 or CodeBlocks (or Visual Studio 6 with service packs). The WinQuake build does use assembly language for speed and the project files compile those easy.

(The structure of the source is a bit more complex than I prefer, partially due to Nehahra support and Direct3D support.)

With the new build (using mark_v.exe), behavior is exactly the same as with the previous version.

Using r_oldwater "1" only fixes liquids and teleporters, but NOT skies. Setting the variable to 0 breaks liquids, too (white surfaces).

Nothing has changed about my hardware setup since post #514, just using newer nvidia driver (v347.52). I have another system with an older nvidia card running on Windows 7 x64 (4GB RAM) which doesn't have show any issues at all, btw. 

If it helps, here is my current config.cfg. Maybe there is another variable in it which I might try changing.

Config.cfg (3KB) 

I'd bet the farm on this being the graphics driver.

And since you provided the version #, maybe I have a shot in addressing it.

(I've seen DarkPlaces users mention certain driver #s being bad several times. I didn't expect this kind of thing to enter my world of "classic Quake appearance engines" but if this driver # can cause the problem, maybe I can target it. Nvidia used to have the reputation of providing stability and ATI was the shoddy/incompatible vendor. I don't claim to know much about graphics card drivers but things I have read makes it sound like they traded places.) 

In the gl version, type gl_clear 1

Does this fix the sky issue?

[The r_oldwater 0 issue is separate deal, I have plan to fix.] 

Setting this through console unfortunately doesn't have any visible effect, sky on start map still looks like in post #533.

My driver settings in nvidia control panel:

My monitor refresh rate is at 120 Hz, if that matters at all. 

Mark V Beta 3

r_oldwater 0 issue gone. Was trying to resize warp image buffer before valid screen width/height determined. 

Fix confirmed, works. ^^ Now all that's left to do is looking up to the sky!

Btw, before you release the final version, is there any chance to add a menu toggle between gl_nearest_mipmap_linear ("classic") and gl_linear_mipmap_linear ("smooth") texture filtering? Currently, you still need to put this into autoexec.cfg if you prefer the "pixel look". 

My pc is saying it's a virus. :D 

I just turned off the virus protection to download it. When I turned the virus protection on again the files were deleted.

Windows 8 doesn't like your program there Baker! 

I think that's rather an issue with your AV. :P I am using Panda Free AV on Win 8.1 here without issues.

The DX8 version (but not the GL version and not the WinQuake version)) somehow triggers Microsoft (and only Microsoft's) malware detection as some old Trojan from 2006.

61 other virus scanners say the dx8 version is not malware.

Go figure ...

No silly virus warnings.

Looks like the skybox problem (drawing the sky in front of geometry) and the external mp3's not playing bugs are both still not fixed.

Also, had to start from a clean install as something in my config is crashing the program back to desktop... 

Water is working now with "r_oldwater 0". I still can't reproduce any problem with the sky. Also tried the config.cfg NightFright posted.

Here is my gl_info:
GL_VENDOR: NVIDIA Corporation
GL_RENDERER: GeForce GT 650M/PCIe/SSE2
GL_VERSION: 4.5.0 NVIDIA 347.52

We have the same driver version, so it could be a 6xx series card vs 7xx issue. 

external mp3s not playing ... please provide more information.

Note: Mark V doesn't support mp3s playing from inside a pak. 

@ericw I see the driver # is same as NightFright's --- so isn't the driver. Hmmm. GeForce 7 series.
