Zandronum has shaders, just the old ones, the custom ones for specific textures only.

GZDoom introduced post-process shaders in the 3.x series, long after going GPL. Zandronum's base is ancient by comparison.

No probs, glad it's of use :)
Is it about Zandronum 3.0?

There was no post-processing shaders support in GZDoom 1.8.6 for sure.
So it appears Zandronum doesn't support shaders then :|

Thanks a ton again, Pixel Eater! You have done great work!

Maintain zoom is in case someone needs to keep the same zoom level that GZDoom has when mouselooking. It's for compatibility with modern ports as DooM didn't originally have mouse look.
A little suggestion: could you please add an option for all the screen scaling (autochthonic+force aspect ratio) to affect the weapon graphic? (see chaingun above)
Unfortunately that is out of my control- the only way to achieve that is to either turn off Bloom and suffer the warping or use Bloom and load a weapon-widening mod. Directly under ScreeM's download link is a file BigButts.wad which has widening information for all of DooM's vanilla weapons.

OK, I got the latest GZDoom and achieved the effect I need for Brutal Doom (scaling the view but not the weapon and status bar) by setting autochthonic widescreen to On and no other aspect ratio correction, so that the view is stretched by the factor of (16:10)/(4:3)=1.2. Thank you so much! BTW, what is the Maintain Zoom option for autochthonic widescreen?

Also, ScreeM description says I should enable bloom. But I don't need it as I play Brutal Doom. Can ScreeM be used without bloom?
It can indeed work without bloom, it will just warp the HUD weapon as you mouselook.
Could you please make a Zandronum version or just tell me how to fix that?

Thanks a lot! Surprisingly no one has done it before in 25-year history of Doom engine.
I prefer Zandronum and encounter the following error on launch:

Code: Select all

Execution could not continue.

Script error, "ScreeM3.5.pk3:gldefs.txt" line 1:
Expected '{' but got identifier 'beforebloom' instead.
Could you please make a Zandronum version or just tell me how to fix that?

It's objectively not. It may seem so if that's what you've grown used to (or convinced yourself is true), but comparisons show the aspect ratio correction makes the face more proportional.
You are right for the status bar face, I admit, but have you seen the powerups, cacodemons and the chaingun?

Yes please. A Gameinfo-block default would be welcome as well in case of custom IWADs (that way any user-submitted maps don't have to remember to add the magic value to their own MAPINFO to work).

No, it won't ;) Doomguy's status bar face seems more proportional to me without ARC, chaingun barrels and barrel bunch as a whole are more circular and not elliptical-cylindric,
also Cacodemons and Pain Elementals are more spherical.

With ARC

And the chaingun:
Without ARC the barrels and barrel bunch as a whole are more circular-cylindric (as a proof, find some cylinder of 3-4 cm diameter, like a C or D size battery, and hold it in front of you about 30 cm lower than the eyes)

while with ARC they're elliptical-cylindric, stretched up-down
