Technically, yes, but given the entirety of the level would be wobbling wildly, it's entirely possible you wouldn't notice this oversight.

My long term plans are to allow specifying custom screen-space shaders via GLDEFS and allow you to specify additional texture sources such as flats or certain gbuffers like depth or face normals. Getting access to the timer uniform is part of this plan too, of course. :D

It's a bit delayed at the moment because I need to make sure the basic system running all this is running reliable on all the hardware gzdoom supports. Really hoping I can get that sorted soon so I can back to more fun stuff!

You can do vertex shaders if you make a file called shaders/glsl/main.vp and put it in your pk3. Base it on shaders/glsl/main.vp from current gzdoom.pk3.

I can't get this to work at all
Any ideas what could be wrong?

This mod was made at a time when it was possible for mods to overwrite core scripts and shaders that exist inside gzdoom.pk3. This "leak" has since been fixed so mods such as this one do not work anymore.

A longer explanation I wrote in another thread for the PSX retro jiggle shader:

GZDoom was fixed to not allow mods to overwrite core (gzdoom.pk3) lumps. This mod was made back when it was possible to exploit this "leak" but it has since been plugged... which is why this mod no longer works.

There are 2 things that could happen for this mod to be functional again (both were stated by dpJudas way back in the last page):

1) Someone integrates this shader properly into the engine and sends a PR for it (has a good chance of happening, if someone steps up).
2) GLDEFS is extended to allow user post process shaders. This has been in discussion for +/- probably a year now, across both forums (here and DRD), so we can probably not expect this to happen anytime soon...

In the mean time, you'll have to use an older version of GZDoom (I can't even remember which one it last worked on).

This mod is a clear reminder of why playing Doom, while strongly under the influence of LSD, is not a good idea! :D :mrgreen:

Maybe rename to mod from "Wobbly Shader" to"Acid Doom", hell add some psychedelic colors into the mix and you have a party!

This worked, thanks!

I never got to try this (or the Retro Shader) before they lost support but the videos looked cool! I tried to fix it but the lens distortion zooms in on one pixel at a time, though the rest mostly works:
Wobbly.pk3

Drunken Doom, minus the Cirrhosis of the Liver, and loss of Brain Cells. :D

That's a winner for me! :mrgreen:

Just pick up your brain cells when you're done... or the zombies will smell them :twisted:

Ahhh, I misread that as "Drunken Doom - Cirrhosis of the Liver + loss of Brain Cells = :mrgreen: "

I need sleep, everything's turning into code :shock:
